Using the plugin with Android library makes java process hang

[stu003]

Trying to use the plugin with a simple Android project consisting of a library and app using it: TestAspectJGradleAndroidLib. Building the project for the first time succeeds. However, the next build fails with the following messages:

Unable to delete directory 'D:\Work_local\from-git\TestAspectJGradleAndroidLib\mylibrary\build'
  Failed to delete some children. This might happen because a process has files open or has its working directory set in the target directory.
  - D:\Work_local\from-git\TestAspectJGradleAndroidLib\mylibrary\build\intermediates\compile_only_not_namespaced_r_class_jar\debug\R.jar
  - D:\Work_local\from-git\TestAspectJGradleAndroidLib\mylibrary\build\intermediates\compile_only_not_namespaced_r_class_jar\debug
  - D:\Work_local\from-git\TestAspectJGradleAndroidLib\mylibrary\build\intermediates\compile_only_not_namespaced_r_class_jar
  - D:\Work_local\from-git\TestAspectJGradleAndroidLib\mylibrary\build\intermediates

Studying running processes shows two java instances (parent and child) rinning with the following command lines:

Killing these processes or restarting Android Studio fixes the problem.
