Doesn't run with retrolambda?

How do i fix this?

warning: [options] bootstrap class path not set in conjunction with -source 1.7 /Users/apple/projects/.../activities/TestActivity.java:375: error: lambda expressions are not supported in -source 1.7 _ratingBar.setOnRatingBarChangeListener((ratingBar, rating, fromUser) -> { ^ (use -source 8 or higher to enable lambda expressions) 1 error 1 warning

I think, that's impossible atm, because retrolambda adds bytecode recompilation step in gradle build chain, and this plugin tries to compile sources by itself.
