Dependency on sources for a module in the same project

I have the following project setup:

Project X
|—> ModuleA
|—> ModuleB

Now i am trying to add a dependency in B for the sources of module A. So in the gradle.build file of Module A i have added the following:

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

configurations {
    packageSources
}

artifacts {
    packageSources sourcesJar
}

And in the gradle.build of Module B i have added:

dependencies {
    compile (
        [project(':ModuleA')],
        [project(path: ':ModuleA', configuration: "packageSources")]
    )
}

The result pom-file that is created when executing clean build install now contains two times the same dependency, both mentioning the normal dependency. I expected one normale dependency and one for the sources.

    <dependency>
      <groupId>some.groupid</groupId>
      <artifactId>ModuleA</artifactId>
      <version>1.0</version>
      <scope>compile</scope>
    </dependency>
    <dependency>
      <groupId>some.groupid</groupId>
      <artifactId>ModuleA</artifactId>
      <version>1.0</version>
      <scope>compile</scope>
    </dependency>

So my question is, how can i add a dependency to ModuleB so that ModuleB includes to sources for ModuleA in it’s resulting POM file.
