NoClassDefFound when used as a peer dependency in Android project

I have a library that depends on better-parse. When I use this library in Android project, it doesn't build. The library has a lot of other dependencies - they don't cause any problems. And also better-parse is not exposed to the project - all calls are wrapped in my library.

Exception in thread "main" java.lang.NoClassDefFoundError: com/github/h0tk3y/betterParse/grammar/Grammar
