Robolectric R$color classDefNotFound

I am trying to write a robolectric unit test within a library (extendlibrary) that depends on another library (baselibrary). Whenever a method in baselibrary tries to access its resource file I get the following error.

java.lang.NoClassDefFoundError: robolectricdemo/com/baselibrary/R$color at robolectricdemo.com.baselibrary.DemoStaticClass.getDemoResource(DemoStaticClass.java:12) at LibraryResourceTest.setUp(LibraryResourceTest.java:25)

    Caused by:

I noticed in the build directory that an R file is only being generated in the package extendlibrary but there is no package for baselibrary. Manually create the R file in a package called baselibrary causes the test to pass. Any ideas on what I could be doing wrong. Posted source at http://ift.tt/1JP9DXo

Update referencing the baselibrarys R file directly in LibraryResourceTest also causes an error saying the R file does not exisit.
