I have the following build.gradle file for my project
apply plugin: 'java'
sourceCompatibility = 1.8
repositories {
mavenCentral()
}
dependencies {
compile 'com.google.guava:guava:23.6-jre';
testCompile group: 'junit', name: 'junit', version: '4.12'
}
jar {
manifest {
attributes 'Main-Class': 'Runner.ClientRunner'
}
}
However, when I run "gradle jar" and attempt to run the given jar, I get the error:
java.lang.NoClassDefFoundError: com/google/common/base/Preconditions
I can't seem to nail down what I've done wrong here, guava is included in the dependencies for gradle and the jar file appears to build fine otherwise (it only crashes when it gets to the first class that depends on guava). Any assistance appreciated.
If it helps I'm doing this from IntelliJ.
I solved my problem using the solution at https://discuss.gradle.org/t/how-to-include-dependencies-in-jar/19571
My build.gradle now looks like
apply plugin: 'java'
sourceCompatibility = 1.8
repositories {
mavenCentral()
}
configurations {
// configuration that holds jars to include in the jar
extraLibs
}
dependencies {
compile 'com.google.guava:guava:23.6-jre';
extraLibs group: 'com.google.guava', name: 'guava', version: '23.6-jre'
testCompile group: 'junit', name: 'junit', version: '4.12'
configurations.compile.extendsFrom(configurations.extraLibs)
}
jar {
manifest {
attributes 'Main-Class': 'Runner.ClientRunner'
}
from {
configurations.extraLibs.collect { it.isDirectory() ? it : zipTree(it) }
}
}

I switched to gradle 7.0 recently and now cannot build my projects jar, with the error
Could not get unknown property 'runtime' for configuration container of type org.gradle.api.internal.artifacts.configurations.DefaultConfigurationContainer.
`
Here is my build.gradle:
apply plugin: 'java'
apply plugin: 'idea'
apply plugin: 'application'

}
dependencies {

}
version = '1.0'
jar {
manifest {
attributes(
'Main-Class': 'classes.RestServer',
)
}
}
task fatJar(type: Jar) {
manifest.from jar.manifest
classifier = 'all'
from {
configurations.runtime.collect { it.isDirectory() ? it : zipTree(it) }
} {
exclude "META-INF/.SF"
exclude "META-INF/.DSA"
exclude "META-INF/*.RSA"
}
with jar
}
artifacts {
archives fatJar
}
Gradle removed the runtime configuration after Gradle 6.x.
You can either change your fatJar task in build.gradle to refer to runtimeConfiguration (as per the Java plugin documentation):
task fatJar(type: Jar) {
manifest.from jar.manifest
classifier = 'all'
from {
// change here: runtimeClasspath instead of runtime
configurations.runtimeClasspath.collect { it.isDirectory() ? it : zipTree(it) }
} {
exclude "META-INF/.SF"
exclude "META-INF/.DSA"
exclude "META-INF/*.RSA"
}
with jar
}
Alternatively use a plugin that deals with fat jar building for you. I've tried Shadow a few years ago. This should also take care of files with the same names from different jars (like META-INF/LICENSE) that you may run into with your approach.
Support for runtime configuration has been stopped gradle-7.0, so configurations.runtime is not working.
Task copyAllDependencies worked for me in gradle-7.0.
Here is the example to copy dependencies into ${buildDir}/output/libs:
Add following to build.gradle.
task copyAllDependencies(type: Copy) {
from configurations.compileClasspath
into "${buildDir}/output/libs"
}
build.dependsOn(copyAllDependencies)
I hope it helps.
It was working fine when external dependencies were in the separate lib folder, but due to change in requirements jar should contain all external dependencies in it, not in a separate folder.
Can anyone Guide me how can I execute the jar file
here is my Gradle file
apply plugin: 'java-library-distribution'
group = 'com.MyCompany'
version = '0.0.1-SNAPSHOT'
description = "data-purge-service"
sourceCompatibility = 1.8

}
jar {
manifest {
attributes "Main-Class": "com.MyCompany.datapurge.service.App"
}
from {
configurations.compile.collect { it.isDirectory() ? it : zipTree(it) }
}
sourceSets {
main {
output.resourcesDir = "build/libs/resources"
}
}
}
When I execute generated jar it is unable to locate dependencies.
What is the way to execute it?
For my case, with gradle version 5 , dependencies were only added when i used configurations.runtimeClasspath instead configurations.compile, as posted in many places.
Here the full task example:
task BuildJar(type: Jar) {
manifest {
attributes(
'Main-Class': 'org.mycompany.mainclass'
)
}
classifier = 'all'
baseName = 'MyJar'
from {
configurations.runtimeClasspath.collect { it.isDirectory() ? it : zipTree(it) }
}
{
exclude "META-INF/*.SF"
exclude "META-INF/*.DSA"
exclude "META-INF/*.RSA"
}
with jar
}
It will create a single jar with everything.
To run the task do:
gradle task BuildJar //use gradew.bat for windows
It will place the jar at ./build/libs
To run just do:
java -jar MyJar.jar
Use Java Decompile to analise the jar.
"In this tutorial, we will show you how to use Gradle build tool to create a single Jar file with dependencies."
I've been looking for a solution for this for 4 days now with no success,
first doing the normal Gradle build task produced a tiny 7kB jar files which obviously didn't work, then i added the jar configuration for the main class:
jar {
manifest {
attributes 'Main-Class': 'Main'
}
}
It's 2MB now!
Still not good enough,
then i found the fatJar/uberJar/shadow tasks, said to be synonymous to the same thing so i tried clean then fatJar tasks on another small RMI app that will run on the server and it worked great, copied it to the main app, it produces and 60MB jar file which looks good but it won't work for some reason,
The app runs perfectly from my IDE (IntelliJIDEA) but the jar produced just does nothing.
So my last option is to consult experts so here we go:
This's the result of the clean task:
6:11:10 PM: Executing external task 'clean'...
:clean
BUILD SUCCESSFUL
Total time: 0.774 secs
6:11:11 PM: External task execution finished
'clean'.
This's the result of the fatJar task:
6:13:13 PM: Executing external task 'fatJar'...
Note: Some input files use unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.
:compileJava
:processResources
:classes
:fatJar

6:13:37 PM: External task execution finished 'fatJar'.

As per the comments here is what was tried.
Making sure a main class is set
Making sure the main class has the same full class name as the one defined
Checking the manifest is valid
Checking the class exists
JavaFX may need a plugin
In the end the last one fixed the issue this was the plugin that fixed the issue.
This was the last comment in the chain:
#jrtapsell Well, this's embarrassing but i'v found the problem, i was unaware that JavaFX apps need a special plugin for Gradle, Using the FiberFox Plugin solved my issue, Thanks for your efforts and may you post answers so that i could upvote you if you like
Running the IDEA IDE I want to add a gradle dependency for the jUnit v5.
Here is my build.gradle file, I used this answer as a guide.
apply plugin: 'java'
sourceCompatibility = 1.8
repositories { mavenCentral() }
apply plugin: 'org.junit.platform.gradle.plugin'
dependencies {
testCompile 'junit:junit:4.12'
compile 'junit:junit:4.12'
testRuntime("org.junit.vintage:junit-vintage-engine:4.12.0-M4")
testCompile("org.junit.jupiter:junit-jupiter-api:5.0.0-M4")
testRuntime("org.junit.jupiter:junit-jupiter-engine:5.0.0-M4")
// Enable use of the JUnitPlatform Runner within the IDE
testCompile("org.junit.platform:junit-platform-runner:1.0.0-M4")
compile ("org.junit.jupiter:junit-jupiter-api:5.0.0-M4")
}
sourceSets {
main {
java {
srcDir 'src'
}
}
}
junitPlatform {
details 'tree'
}
The problem here is that the jUnit4 annotations are resolved by import but all the v5 annotations are not resolved.
One example:
#ParameterizedTest
public void testExample() {
// My annotations is not resolved
}
What is the right way to add a jUnit5 dependency using gradle?
EDIT
I started a new gradle java project from scratch to get to the bottom of this.
Here is my current build.gradle.
group 'com.iay0361'
version '1.0-SNAPSHOT'
apply plugin: 'java'
sourceCompatibility = 1.8
repositories { mavenCentral() }
apply plugin: 'org.junit.platform.gradle.plugin'
dependencies {
testCompile group: 'org.junit.vintage', name: 'junit-vintage-engine', version: '4.12.0-RC3'
testCompile group: 'org.junit.jupiter', name: 'junit-jupiter-api', version: '5.0.0-RC3'
testCompile group: 'org.junit.jupiter', name: 'junit-jupiter-engine', version: '5.0.0-RC3'
compile group: 'org.junit.jupiter', name: 'junit-jupiter-params', version: '5.0.0-RC3'
testCompile group: 'org.junit.platform', name: 'junit-platform-runner', version: '1.0.0-RC3'
}
sourceSets {
main {
java {
srcDir 'src'
}
}
}
junitPlatform {
details 'tree'
}
I wrote the #Test annotation in a new class file under test after which it asked me to "add the 'jUnit5' to classpath
which I did and this time selected the Copy 'jUnit5' libraries to... instead of using the IDEA distributor.
Now it added these files in module:
The file is still RC2 but in build.gradle it is RC3.
There are also no jUnit jars in "External Library" directory
What am I missing, the problem is still that the IDE cannot resolve some jUnit5 annotations like #ParamiterizedTest.
Here is a quick sample on how to configure gradle with junit5. In your dependencies, remove the compile statement for the junit:4.12 artifact verison.
// If you also want to support JUnit 3 and JUnit 4 tests
testCompile("junit:junit:4.12")
In the buildscript() method, include these:
buildscript {
repositories { mavenCentral() }
dependencies { classpath 'org.junit.platform:junit-platform-gradle-plugin:1.0.0-RC3' }
}
I'm using the Microsoft JDBC Driver 4.1 to connect to SQL Server. In Eclipse I have added the .jar file to the class path of my project ( C:\Program Files\Microsoft JDBC Driver 4.1 for SQL Server\sqljdbc_4.1\enu\sqljdbc41.jar).
I've added this .jar to a folder called lib in my project and am trying to have this .jar added as part of my .jar:
repositories {
mavenCentral()
}
dependencies {
compile files('lib/sqljdbc41.jar')
testCompile group: 'junit', name: 'junit', version: '4.+'
}
However, sqljdbc41.jar is not included in my .jar. Am I missing something?
You have to create a (application) distribution to package your libraries and application jar in a folder: http://gradle.org/docs/current/userguide/application_plugin.html
Alternatively you can use a plugin like https://github.com/johnrengelman/shadow to create a self-contained uberjar.
Thanks chromanoid. I was able to solve the problem two ways. First I placed the sqljdbc41.jar in a new folder called lib in my project. Solution 1 was to create an application distribution:
apply plugin:'application'
apply plugin: 'java'
mainClassName = "main.java.application.Main"
repositories {
mavenCentral()
}
dependencies {
runtime files('lib/sqljdbc41.jar')
testCompile group: 'junit', name: 'junit', version: '4.+'
}
You can then create a distribution using the distZip task. Solution 2 was to create a fat jar.
apply plugin: 'java'
repositories {
mavenCentral()
}
configurations {
provided
compile.extendsFrom provided
}
dependencies {
runtime files('lib/sqljdbc41.jar')
testCompile group: 'junit', name: 'junit', version: '4.+'
}
jar {
dependsOn configurations.runtime
from {
(configurations.runtime - configurations.provided).collect {
it.isDirectory() ? it : zipTree(it)
}
} {
exclude "META-INF/*.SF"
exclude "META-INF/*.DSA"
exclude "META-INF/*.RSA"
}
}
and use the build task.
