java - How to build sources jar with gradle?

Question

I am working with an open source project that is built with gradle. I would like to generate a (project)-sources.jar file that I can load into my IDE (IntelliJ IDEA) and debug through the project. I know how to load the file if I can generate it.

I have looked through the available gradle tasks for the project and there isn't one that generates a sources jar file.

What is the easiest way to generate a sources jar file for this project?

Adding the source into the jar file that contains the compiled class files would be fine as well.

Answer 1

task sourcesJar(type: Jar, dependsOn: classes) {
    classifier = 'sources'
    from sourceSets.main.allSource
}

task javadocJar(type: Jar, dependsOn: javadoc) {
    classifier = 'javadoc'
    from javadoc.destinationDir
}

artifacts {
    archives sourcesJar
    archives javadocJar
}
