Android Execution failed for task ':com.mines.testapp:processDebugResources'?

I was trying to compile a yyc .apk, but there's a build fail. Resource linking failed, looks like a font-related issue.

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':com.relicplay.testapp:processDebugResources'.
