Android apklib: Doublicate R.java

Question

I have an Android project with a dependency to a apklib project. In the apklib project a R.java file will be generated and packed into the result apklib file. The Android project unzip it via android plugin and rebuild all code. In consequence of this there are a doublicate R file compilation error cause the plugin try to rebuild the R file of the apklib project resources in the Android project.

What is the problem? Here my snippets from the pom files:

The problem is that the in the apklib generated R.java file is copied into the gen folder of the Android project by the aapt tool (V. 19). I work with Windows platform, maven 3.1.1 and the android maven plugin 3.8.0 on both projects.
