java - Add classpath in manifest using Gradle

Question

I would like my Gradle build script to add the complete Classpath to the manifest file contained in JAR file created after the build.

Example:

Manifest-Version: 1.0
Class-Path: MyProject.jar SomeLibrary.jar AnotherLib.jar

My build script already add some information to the manifest this way:

jar {
    manifest {
        attributes("Implementation-Title": project.name,
            "Implementation-Version": version,
            "Main-Class": mainClassName,
    }
}

How do I get the list of dependencies to add to the manifest?

Found a solution on Gradle's forum:

jar {
  manifest {
    attributes(
      "Class-Path": configurations.compile.collect { it.getName() }.join(' '))
  }
}
