I'm trying to use Lombok in my project that I'm developing using IntelliJ IDEA 11.
I've installed 3rd-party plugin for IDEA and it seems working fine because IDEA sees all autogenerated methods/fields.
So I have a class that uses Slf4j. I annotated it like this
import lombok.extern.slf4j.Slf4j;
#Slf4j
public class TestClass
{
public TestClass()
{
log.info("Hello!");
}
}
But when I build my project compiler spits: cannot find symbol variable log.
Could you please tell me what I'm missing here?
Update: It turned out it's RequestFactory annotation process that fails.
input files: {com.zasutki.courierApp.server.TestServlet, com.mine.courierApp.server.model.DatastoreObject}
annotations: [javax.inject.Singleton, javax.inject.Inject, lombok.Getter, lombok.Setter, com.googlecode.objectify.annotation.Id, com.googlecode.objectify.annotation.OnSave]
Processor com.google.web.bindery.requestfactory.apt.RfValidator matches [lombok.Getter, com.googlecode.objectify.annotation.Id, javax.inject.Inject, lombok.Setter, com.googlecode.objectify.annotation.OnSave, javax.inject.Singleton] and returns false.
cannot find symbol variable log
Any ideas on workarounds?
Update2: Perhaps it's not something readers want to hear but I ended up switching to Scala.
I have fixed it in IDEA 12 by setting check box Enable annotation processing in:
Settings -> Compiler -> Annotation Processors
For IDEA 2016.2:
Preferences... > Build, Execution, Deployment > Compiler > Annotation Processors
After enabling, run Build -> Rebuild Project to have annotations recognized and eliminate errors.
For IDEA 2019.2.1, depending on how the project is configured, installing the Project Lombok plugin may not be sufficient. Here is another way to use Project Lombok with IntelliJ IDEA:
Visit https://projectlombok.org/download
Download the JAR file into the project lib directory (e.g., $HOME/dev/java/project/libs).
Start the IDE.
Click File 🠖 Settings.
Expand Build, Execution, Deployment 🠖 Compiler 🠖 Annotation Processors.
Ensure Enable annotation processing is checked.
Ensure Store generates sources relative to is selected based on the project's module settings (if Module output directory doesn't work, come back and try the other setting).
Click Apply.
Click Plugins.
Click Marketplace.
Set search field to: lombok
Install Lombok.
Click OK.
Restart the IDE if prompted.
Click File 🠖 Project Structure.
Select Libraries.
Click the + symbol to add a new project library (or press Alt+Insert).
Select Java.
Set the path to: $HOME/dev/java/project/libs/lombok.jar
Click OK.
Select the modules to apply.
Click OK.
Optionally, rename lombok to Project Lombok 1.18.8.
Click OK.
The project can now import from the lombok package and use Project Lombok annotations (e.g., lombok.Setter and lombok.Getter).
Picture representation of resolving this issue.
First enable annotation processors and try. This may or may not work.
Post that, you can install the lombok plugin from intellij, (After installation Intellij will restart to enable the plugin, so make sure you save your work.(Intellij does save all the changes before restart, just to be on the safe side.)) screenshot below:
Enabling annotation processing will make it work
But if you are on a Mac, make sure you enable annotation processing(tick the checkbox) from both the places available.
1.) Intellij Idea -> Preferences -> Compiler -> Annotation Processors
2.) File -> Other Settings -> Default Settings -> Compiler -> Annotation Processors
Make sure it's added correctly to your project.
example for Gradle:
dependencies {
compileOnly 'org.projectlombok:lombok:1.18.8'
annotationProcessor 'org.projectlombok:lombok:1.18.8'
...
}
Install Lombok plugin for your IDE
Check "Enable annotation processing" checkbox in IDE (IntellijIdea), have no idea if there is anything like this for other IDEs like Eclipse.
in the latest Gradle version you should use annotationProcessor:
compileOnly 'org.projectlombok:lombok'
annotationProcessor 'org.projectlombok:lombok:1.18.8'
I'm using IntelliJ IDEA 2020.3 (Community Edition)
Here, besides install the Lombok plugin and enable annotations (explained by other answers). I also needed to set the flag -Djps.track.ap.dependencies=false to the Build Process Option¹.
I didn't need to use the -javaagent approach, neither setup the classpath.
¹. Go to: File | Settings | Build, Execution, Deployment | Compiler | "Shared build process VM options" field

Just for reference using IntelliJ 2018.3, I solved this issue (using #Data annotation to insert getter/setter) following the three steps:
File -> Settings -> Build, Execution, Deployment -> Annotation Processors -> Enable Annotation Processing;
Do remember to Apply the change.
Install plugin lombok in the same setting dialog;
It seems good enough for now, it requires to restart IntelliJ and then rebuild your project.
Best wishes :)
If you have checked both these steps as follows
Enable annotations : this is a check done in IntelliJ
preferences.
Importing lombok into IntelliJ classPath
(Preferences -> Plugins)
and still getting errors then please check the compiler - if it is JAVAC or ECLIPSE.
You can check the compiler in Preferences -> Build,Execution,Deployment -> Compiler -> Java Compiler.
Change the Use compiler to Javac (if it is Eclipse). This is what worked for me.
Including the following in the pom.xml is what worked for me:
<build>
<defaultGoal>spring-boot:run</defaultGoal>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>${java.version}</source>
<target>${java.version}</target>
<annotationProcessorPaths>
...
<path>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>${lombok.version}</version>
</path>
</annotationProcessorPaths>
</configuration>
</plugin>
</build>
As noted here, quote: "You should activate external compiler option and enable annotation processors or disable external compiler and disable all of annotation compilers to work with lombok". This fixed my problem. Note that I added the Scala plugin prior to receiving this error, so I suspect the plugin changed some of the above settings.
there is a plugin for intellij. see here: https://projectlombok.org/download.html
Do you have lombok as dependency of your project? lombok.jar must be on the classpath during compiling of the project, which is using any of lombok-annotations.
For those of you who are still having trouble:
In addition to the above steps of enabling annotation processors and installing the IntelliJ Lombok plugin, I also had to Build -> Rebuild Project.
1、install lombok plugin for IDEA
Intellij Idea -> Preferences -> Plugins -> type in lombok -> Search in Repositories -> install -> restart IDEA
2、 config lombok plugin
Enabling annotation processing will make it work
But if you are on a Mac, make sure you enable annotation processing in the following two places:
Intellij Idea -> Preferences -> Build, Execution, Deployment -> Compiler -> Annotation Processors, check the checkbox of "Enable annotation processing".
File -> Other Settings -> Default Settings -> Build, Execution, Deployment -> Compiler -> Annotation Processors, check the checkbox of "Enable annotation processing".
I was on Mac
This is my IntelliJ IDEA and Mac Version - IntelliJ IDEA 2017.1.5 Build #IU-171.4694.70 --- Mac OS X 10.12
In addition to enabling annotation processing (tick the checkbox) at these 2 places.
1.) Intellij IDEA -> Preferences -> Compiler -> Annotation Processors
.
2.) File -> Other Settings -> Default Settings -> Compiler -> Annotation Processors
I had to install Lombok plugin too to make it work.
3.) Intellij IDEA -> Preferences -> Plugins ->Browse Repositories-> Search for "Lombok"-> install plugin -> Apply and restart IDEA
It didn#t work for me with any of the above solutions. I added <scope>provided</scope> to the dependency in pom.xml and it worked.
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>1.16.20</version>
<scope>provided</scope>
</dependency>
If you already installed it, then for refresh just deselect and select Enable annotation in Intellij Settings.
I have faced this problem after updating the IDEA to 2018.3. I had to update all the existing plugin
After trying all the suggestions here, I have also find another kind of solution. It seems that sometimes IDEA can not obtain processors from project classpath.
So, on the Annotation Processors settings tab, you have to manually specify Processor path.
Apart from mentioned in all answers I have to add the below code in pom.xml configuration to makes mvn clean install work. Before adding this code I was getting cannot found symbol for getters and setters.
<annotationProcessorPath>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>1.18.8</version>
</annotationProcessorPath>
For me what worked:
I uninstalled the installed the Lombok plugin freshly
I ticked "Enable Annotation Plugin"
I selected "Obtain processor from the project classpath" in the same page
For IntelliJ IDEA 2020.1.1 enabling Kotlin plugin fixed this issue.
If you did everything mentioned in this question and It's still failing, don't forget to remove /target folder under your projects. And If it's still failing, restart your IDE.
And If it's still failing restart your computer.
The Jetbrains IntelliJ IDEA editor is compatible with lombok without a plugin as of version 2020.3.
I was using 2020.2 version, i updated to 2020.3 it worked just like that.
I don't think I read my final step in the answers yet. (Mac + IntelliJ Ultimate 2020.1)
Its just a silly cause in my case, but those are the ones that can take up most time because the error doesnt directly refer to it.
The same lombok error appeared to me after deleting and recloning the project.
After doing the steps mentioned earlier in this thread I still had the error, I then discovered my SKD was defaulted to version 11. I changed this back to 1.8 and everything worked again.
File --> Project Settings --> Project
I changed the Project SDK and the Project language level to 1.8
PS the location for the default settings on the mac is different in this IntelliJ version than mentioned before :
File --> New Project Settings --> Preferences for new Projects --> Build, Execution, Deployment --> Compiler --> Annotation Processors --> 'check' Enable annotation processing
Hope this helps anybody
If none of the above did'nt work , then try to change File->Project Structure->Project->Project Language Level > 8 Lambda,type annotations (Not SDK Default 8)
This worked for me .
I tried enabling lambok, restarted intellij, etc but below worked for me.
Intellij Preferences ->Compiler -> Shared Build process VM Options and set it to
-Djps.track.ap.dependencies=false
than run
mvn clean install
It may happen that even if you have it configured properly and it is visible among the libraries and in Gradle dependencies list, IntelliJ still does not have it in class path. Or it is there, but configured with different scope (ex: test instead of compile.)
First, make sure you have plugin installed and annotation processing enabled, as stated in other answers.
If you still have annotation not recognized, place cursor on it, hit ALT+ENTER (or OPTION+ENTER) and see if you have a menu option Add library: Gradle: org.projectlombok:lombok:VERSION to class path. If you can see it, choose this one and it may solve your problem.
You may check the library and it's scope in:
Project settings / Modules / Dependencies tab (search for lombok in there)
I had a similar issue when building with JDK8, set the project back to JDK7 and it worked fine. Could be an older version of Lombok that won't compile under JDK8.
If you tried all solutions presented here and still can't compile sources, also look here: Static import of builder class breaks bytecode generation in Maven - look at your sources if it has such static imports. This affects maven plugin, so compilation will fail on other build systems outside IntelliJ IDEA.
I have a project (in Java 11) consisting of multiple modules. And one module is exluded from the build, so it is commented out in the list of modules in the <modules> tag in pom.xml. The reason is, that it is kindof broken and does not (yet) compile. It is to be fixed in the future. And indeed, when I run the maven build, the build runs fine, the "broken" model does not participate in the build. But when I want to compile changes using the "Build project" button in IntelliJ Idea (version 2018.1.5. Community) then it wants to compile the broken module too and crashes. My workaround so far was simply to add this module to the list of excludes under Settings -> Build, Execution, Deployment -> Compiler -> Excludes. And this works, but other colleagues say, for them it works even without this workaround, so for them the compilation does not touch this module without any additional steps. When entering those classes, there is nothing red on their machines. And now I need to figure out, what could be the reason, why for me it works only with this custom adding the module to exludes? I already tried to "Reimport all maven projects", it did not help. Might there be any IDE settings responsible for not compiling such projects? Any ideas?
I found the reason :) Obviously IntelliJ Idea Professional automatically ignores such modules (which are commented out in pom.xml) and "Build project" does not compile them. But in community edition (which I am using) when I create the project there is a window showing up which is titled "Import maven projects". There I simply had to switch off the checkbox with the "broken" module and this lead to the same result :)
You can exclude files/directories directly from the project view:
Just open right-mouse-menu -> Mark Directory As -> Exclude
My project was working and everything was fine but have no idea what happened suddenly that I'm getting error when I want to build my project. This is Gradle output:
/Users/admin/Desktop/android/MY-Project/build/intermediates/res/project/debug/values/values.xml:265: error: Resource entry com.crashlytics.android.build_id is already defined.
/Users/admin/Desktop/android/MY-Project/build/intermediates/res/project/debug/values/com_crashlytics_build_id.xml:9: Originally defined here.
Since both of these files are auto generated I cannot do anything :(
I tried to clean project by Build>"Clean project" but nothing happened.
I tried to clean project by ./gradlew clean assembleDebug but nothing happened.
I tried to invalidate cache of Android Studio by File>"Invalidate caches / Restart" but nothing happened.
I even restarted my f.laptop but still same problem displays when I build the project.
I have this classpath in my build script but as mentioned it was working...
dependencies {
classpath 'com.android.tools.build:gradle:1.0.1'
classpath 'com.crashlytics.tools.gradle:crashlytics-gradle:1.+'
}
Any suggestion would be appreciated. Thanks.
I have an app of two flavors: Debug and Release, with two manifests and two distinct packages com.myapp.release and com.myapp.debug for each flavor, respectively.
After migration from Fabric.io to Firebase Crashalytics, a Gradle warning
appeared about duplicate com_crashlytics_build_id.xml:
/home/.../app/build/generated/fabric/res/flavor1/debug/values/com_crashlytics_build_id.xml [string/com.crashlytics.android.build_id] /home/.../app/build/generated/crashlytics/res/flavor2/debug/values/com_crashlytics_build_id.xml: Error: Duplicate resources
Fix:
in build.gradle
remove
dependencies {
classpath 'io.fabric.tools:gradle:1.+'
}
remove
apply plugin: 'io.fabric'
I had the same problem.
My mistake is I add fabric plugin and firebaseCrashlytics plugin on my gradle.
(reason : plugin build id duplicate crash)
You must fix select A and B plugin.
A : apply plugin: 'com.google.firebase.crashlytics
B : apply plugin: 'io.fabric
I had the same problem, one of my dependencies had mistakenly added the com.crashlytics.android.build_id via craslytics's auto genereted xml file.
It was a library project and deleting :
library/src/main/assets/crashlytics-build.properties
library/src/main/res/values/com_crashlytics_export_strings.xml
fixed it for me.
Fix different io.fabric.tools:gradle versions
Different io.fabric.tools:gradle versions in the app and library caused this for me.
I'd the following in the app's build.gradle:
classpath 'io.fabric.tools:gradle:1.19.2'
And the following in the library's build.gradle:
classpath 'io.fabric.tools:gradle:1+'
I changed both to following to fix it:
classpath 'io.fabric.tools:gradle:1.19.2'
PS: We need better error messages. As programmers we waste of lot of time when the error messages are not only bad, but as in this case, downright misleading.
remove this also besides fabric
crashlytics {
enableNdk true
}
This question already has answers here:
Can't compile project when I'm using Lombok under IntelliJ IDEA
(43 answers)
Closed 3 years ago.
I've installed the plugin for intellij idea(lombok-plugin-0.8.6-13).
Added lombok.jar into classpath
I can find getters and setters in the window of structure. And Intellij shows no error.
Setting - Lombok plugin - Verified Intellij configuration for lombok, it shows that "configuration of IntelliJ seems to be ok".
It seems everything is OK. But when I compile a test, errors come: can not find the methods getXXX and setXXX.
I opened the .class file with IntelliJ and find out that there is no setXXX and getXXX methods.
Could somebody tell me why?
plugin:lombok-plugin-0.8.6-13
lombok.jar:1.14.0
idea:13.0.2 for linux
jdk:1.7.0_21
In order to solve the problem set:
Preferences (Ctrl + Alt + S)
Build, Execution, Deployment
Compiler
Annotation Processors
Enable annotation processing
Make sure you have the Lombok plugin for IntelliJ installed!
Preferences -> Plugins
Search for "Lombok Plugin"
Click Browse repositories...
Choose Lombok Plugin
Install
Restart IntelliJ
If you're using Eclipse compiler with lombok, this setup finally worked for me:
IDEA 14.1
Lombok plugin
... / Compiler / Java Compiler > Use Compiler: Eclipse
... / Compiler / Annotation Processors > Enable annotation processing: checked (default configuration)
... / Compiler > Additional build process VM options:(Shared build process VM options) -javaagent:lombok.jar
The most important part is the last one, mine looks like following:
Plugin is needed for IntelliJ editor to recognize getters and setters, javaagent is needed for eclipse compiler to compile with lombok.
If you're using Intellij on Mac, this setup finally worked for me.
Installations: Intellij
Go to Preferences, search for Plugins.
Type "Lombok" in the plugin search box. Lombok is a non-bundled plugin, so it won't show at first.
Click "Browse" to search for non-bundled plugins
The "Lombok Plugin" should show up. Select it.
Click the green "Install" button.
Click the "Restart Intellij IDEA" button.
Settings:
Enable Annotation processor
Go to Preferences -> Build, Execution,Deployment -->Preferences -> Compiler -> Annotation Processors
File -> Other Settings -> Default Settings -> Compiler -> Annotation Processors
Check if Lombok plugin is enabled
IntelliJ IDEA-> Preferences -> Other Settings -> Lombok plugin -> Enable Lombok
Add Lombok jar in Global Libraries and project dependencies.
File --> Project Structure --> Global libraries (Add lombok.jar)
File --> Project Structure --> Project Settings --> Modules --> Dependencies Tab = check lombok
Restart Intellij
I followed this procedure to get ride of a similar/same error.
mvn idea:clean
mvn idea:idea
After that I could build both from the IDE intellij and from command line.
For me, both lombok plugin and annotation processing enable needed, no else. No need to Use Eclipse and additional -javaagent:lombok.jar options.
Idea 14.1.3, build 141.1010
Lombok plugin[Preference->plugins->browse repositories->search 'lombok'->install and restart idea.
Preference ->search 'annotation'->enter annotation processor ->enable annotation processing.
After spending far too long troubleshooting this, I found a simple workaround which ensures IntelliJ processes Lombok annotations correctly during builds.
The gradle-lombok plugin is not necessary for this workaround. Your build.gradle only requires the following:
dependencies {
compileOnly("org.projectlombok:lombok:1.16.18")
}
The workaround is to turn on the following IntelliJ setting:
Open IntelliJ preferences/settings.
Navigate to Build, Execute, Deployment > Build Tools > Gradle > Runner
Check the box labeled Delegate IDE build/run actions to gradle
Benefits of this workaround compared to other solutions on this page:
No annotation processing necessary!
Able to use the Java compiler of your choice (no Eclipse compiler necessary)
No use of buggy gradle-lombok plugin (although perhaps someone else can solve this)
No VM options necessary
No hard-coded paths to lombok jar
One downside is that IntelliJ will no longer use its own test runner. Instead, tests are always run through Gradle.
IDEA 2016.1:
Install lombok plugin
Settings -> Compiler -> Annotation Processors -> Enable annotation processing: checked (default configuration)
Settings -> Compiler -> Annotation Processors -> Annotation Processors add "lombok.launch.AnnotationProcessorHider$AnnotationProcessor"
Also if you are using maven add to maven-compiler-plugin configuration -> annotationProcessors -> annotationProcessor: lombok.launch.AnnotationProcessorHider$AnnotationProcessor
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>${maven.plugin.compiler.version}</version>
<configuration>
<compilerVersion>${java.version}</compilerVersion>
<source>${java.version}</source>
<target>${java.version}</target>
<annotationProcessors>
<annotationProcessor>lombok.launch.AnnotationProcessorHider$AnnotationProcessor</annotationProcessor>
</annotationProcessors>
</configuration>
</plugin>
Make sure these two requirements are satisfied:
Enable annotation processing,
Preferences > Build, Execution, Deployment > Compiler > Annotation Processors > Enable annotation processing
Lombok plugin is installed and enabled for your project.
None of the advanced answers to this question resolved the problem for me.
I managed to solve the problem by adding a dependencie to lombok in the pom.xml file, i.e. :
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>1.16.12</version>
</dependency>
I am using IntelliJ 2016.3.14 with maven-3.3.9
Hope my answer will be helpful for you
On Itellij 15 CE, it's enough to just install Lombok Plugin (no additional configuration required).
I am unable to get this working with the javac compiler, and I get the same error.
Error:(9, 14) java: package lombok does not exist
I have enabled annotation processor, and have also tried rebuilding the project, invalidate cache/restart. Doesn't help.
I did however get it to work partially with eclipse compiler. I say partial because although the build passes successfully, the editor still complains about "Cannot resolve symbol".
Idea - 15.04 community edition
Lombok - 1.16.6
Lombok plugin (https://github.com/mplushnikov/lombok-intellij-plugin) - 0.9.8
JDK - 1.8.0_51
Update:
Ok, I finally got this working. Mine was a gradle project, and lombok was configured as a custom "provided" configuration. Worked fine after adding this in build.gradle
idea {
module {
scopes.PROVIDED.plus += [configurations.provided]
}
}
So, 3 steps
Install Lombok plugin from File->Settings->Plugins
Enable Annotation Processor (javac compiler works too)
Ensure that you have build.gradle or pom.xml updated for idea if you are adding lombok as a custom config.

File -> Other Settings -> Default Settings -> Build, Execution, Deployment -> Compiler -> Annotation Processors, check the checkbox of "Enable annotation processing".
I was on Mac
This is my IntelliJ IDEA and Mac Version - IntelliJ IDEA 2017.1.5 Build #IU-171.4694.70 --- Mac OS X 10.12
In addition to enabling annotation processing (tick the checkbox) at these 2 places.
1.) Intellij IDEA -> Preferences -> Compiler -> Annotation Processors
.
2.) File -> Other Settings -> Default Settings -> Compiler -> Annotation Processors
I had to install Lombok plugin too to make it work.
3.) Intellij IDEA -> Preferences -> Plugins ->Browse Repositories-> Search for "Lombok"-> install plugin -> Apply and restart IDEA
It didn#t work for me with any of the above solutions. I added <scope>provided</scope> to the dependency in pom.xml and it worked.
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>1.16.20</version>
<scope>provided</scope>
</dependency>
If you already installed it, then for refresh just deselect and select Enable annotation in Intellij Settings.
I have faced this problem after updating the IDEA to 2018.3. I had to update all the existing plugin
After trying all the suggestions here, I have also find another kind of solution. It seems that sometimes IDEA can not obtain processors from project classpath.
So, on the Annotation Processors settings tab, you have to manually specify Processor path.
Apart from mentioned in all answers I have to add the below code in pom.xml configuration to makes mvn clean install work. Before adding this code I was getting cannot found symbol for getters and setters.
<annotationProcessorPath>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>1.18.8</version>
</annotationProcessorPath>
For me what worked:
I uninstalled the installed the Lombok plugin freshly
I ticked "Enable Annotation Plugin"
I selected "Obtain processor from the project classpath" in the same page
For IntelliJ IDEA 2020.1.1 enabling Kotlin plugin fixed this issue.
If you did everything mentioned in this question and It's still failing, don't forget to remove /target folder under your projects. And If it's still failing, restart your IDE.
And If it's still failing restart your computer.
The Jetbrains IntelliJ IDEA editor is compatible with lombok without a plugin as of version 2020.3.
I was using 2020.2 version, i updated to 2020.3 it worked just like that.
I don't think I read my final step in the answers yet. (Mac + IntelliJ Ultimate 2020.1)
Its just a silly cause in my case, but those are the ones that can take up most time because the error doesnt directly refer to it.
The same lombok error appeared to me after deleting and recloning the project.
After doing the steps mentioned earlier in this thread I still had the error, I then discovered my SKD was defaulted to version 11. I changed this back to 1.8 and everything worked again.
File --> Project Settings --> Project
I changed the Project SDK and the Project language level to 1.8
PS the location for the default settings on the mac is different in this IntelliJ version than mentioned before :
File --> New Project Settings --> Preferences for new Projects --> Build, Execution, Deployment --> Compiler --> Annotation Processors --> 'check' Enable annotation processing
Hope this helps anybody
If none of the above did'nt work , then try to change File->Project Structure->Project->Project Language Level > 8 Lambda,type annotations (Not SDK Default 8)
This worked for me .
I tried enabling lambok, restarted intellij, etc but below worked for me.
Intellij Preferences ->Compiler -> Shared Build process VM Options and set it to
-Djps.track.ap.dependencies=false
than run
mvn clean install
It may happen that even if you have it configured properly and it is visible among the libraries and in Gradle dependencies list, IntelliJ still does not have it in class path. Or it is there, but configured with different scope (ex: test instead of compile.)
First, make sure you have plugin installed and annotation processing enabled, as stated in other answers.
If you still have annotation not recognized, place cursor on it, hit ALT+ENTER (or OPTION+ENTER) and see if you have a menu option Add library: Gradle: org.projectlombok:lombok:VERSION to class path. If you can see it, choose this one and it may solve your problem.
You may check the library and it's scope in:
Project settings / Modules / Dependencies tab (search for lombok in there)
I had a similar issue when building with JDK8, set the project back to JDK7 and it worked fine. Could be an older version of Lombok that won't compile under JDK8.
If you tried all solutions presented here and still can't compile sources, also look here: Static import of builder class breaks bytecode generation in Maven - look at your sources if it has such static imports. This affects maven plugin, so compilation will fail on other build systems outside IntelliJ IDEA.
