New to Gradle. I Apologize if this is a bad question.
I've been trying to start a plain Java8 Gradle project. Everything was great until I tried to add Lombok to my project.
My Intellij IDE has all the settings required for Lombok.
Lombok plugin installed and activated
Annotation processor is on
The IDE is handling the annotations perfectly. No errors showing, and the boilerplate is shown in the code structure.
However, when I try to build the project or run the main method using Intellij, the compiler complains that the boilerplate Lombok is supposed to generate doesn't exist.

Even if you don't want to use spring, head over to the spring Initializer at https://start.spring.io/ and choose Gradle and add the Lombok dependency. It'll create a build.gradle for you with Lombok in the appropriate configurations (including annotationProcessor)

What I tried so far with no success:
add maven certificate to jvm cacerts
What I am using
gradle 7.4
jdk and jre 11
ubuntu 20.04 (raspberry aarch64)
The maven repo exists and I am a bit hopeless what should I do. Any suggestions?
Thanks in advance if you can help!
UPDATE:
As #dave_thompson_085 recommended, I ran the build with stacktrace and got the following error:
java.security.KeyManagementException: problem accessing trust store
Tried to reinstall java but the same problem exist.
If anyone runs into the same problem as me just set the variable for
javax.net.ssl.trustStore
to where your cacerts are located.
For me it was: /usr/lib/jvm/java-11-openjdk-arm64/lib/security/cacerts
If you don't want to add this parameter every time when you are trying to build here is a solid solution for that.
I want to using GraalVM in my Spring Boot 2.3.10.RELEASE project because it can decrease the memory usage of JVM(Now I am using JDK 11), so I add the dependencies:
api "org.springframework.experimental:spring-native:0.10.2"
add the gradle plugin:
apply plugin: "com.github.ayltai.spring-graalvm-native-plugin"
add native build config:
nativeImage {
mainClassName = 'com.dolphin.soa.manage.AppStarter'
traceClassInitialization = true
reportExceptionStackTraces = true
removeUnusedAutoConfig = true
removeYamlSupport = true
removeSpelSupport = true
removeJmxSupport = true
maxHeapSize = '4G'
}
finnaly I am using this Gradle(7.0) command to build a native jar:
./gradlew clean :dolphin-manage:dolphin-manage-service:bootBuildImage -x test
but show this error:

(base)
is it a compatible problem about GraalVM and lombok? is it possible to fix it?
I'm seeing this same type of error running spotless on my Java project. I just reported a bug about this to them: https://github.com/diffplug/spotless/issues/1244
I diagnosed the problem as some kind behavioral change between Java 15 and Java 16. So one thing you can do is revert to an earlier version of Java to see if that makes the issue go away. If it does, you should report a bug similar to what I did to the project with the problem so they can try to fix it.

When I try to do gradle run, I am getting an error::compileJava Task failed.
How can this be solved? I cannot try kotlin because I have some dependency and I want to execute this only in gradle.build. I am using gradle version 6.6 which is also due to the dependency of project.

//This replaces project.properties w.r.t. build settings
project.ext {

defaultTargetSdkVersion=27 //Integer - We ALWAYS target the latest by default
defaultCompileSdkVersion=27 //Integer - We ALWAYS compile with the latest by default
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
Here things I have done:
I changed the defaultCompileSdkVersion from 27 to 28 same result.
I added
configurations.all {
resolutionStrategy {
force 'com.android.support:support-v4:27.1.0'
}
}
at the bottom of the build.gradle same.
I removed the build and re-install it, same error.
I am out of option.
Thank you for your help in advance.

try using Java 6 , gradle has some known issues with java 7
Add hadoop-core-1.x.y.jar from hadoop distribution to path.
This worked for me in CoPA example. I added to eclipse build path.
Add this to gradle dependencies{} section
compile( group: 'org.apache.hadoop', name: 'hadoop-core', version: '1.2.0' )
It seems like class not found, please check libraries in build path entries.
I had the same issue today trying the Cascading for the Impatient tutorial. I have solved adding the following to my build.gradle in the dependenciessection :
compile 'org.apache.hadoop:hadoop-client:2.3.0'
I wanted to use Hadoop 2.3.0, but I guess that you can choose your own version of Hadoop.
PS : In order to use the first hadoop-mapred package, you have to add the following instead :
compile 'org.apache.hadoop:hadoop-mapred:0.22.0'
You can find all the repos you might need for Hadoop here.
Thanks Lalit,
Adding the below line did the trick for me without have to change any java version..
compile( group: 'org.apache.hadoop', name: 'hadoop-core', version: '1.2.0' )
Alternatively, I can even add the hadoop-core jar in the class path and mention that in the gradle path
