AssertJ with Robolectric and Java project, distribute as jar artifact

[bademux]

Hello,
Can you please distribute AssertJAndroid like jar without support-annotation dependency?
It is a little bit problematic to use it with project like https://github.com/bademux/deckard-gradle.
I use separate Java Project (AS module) to run gradle test.

Thanks for cool lib
