Retrolambda breaks lint

See original GitHub issue

Related to #69, but figured I’d open a more general issue for discussion and the hope that someone has come up with a creative solution to this.

As of right now, the version of Lombok used by the linter doesn’t support lambdas, which causes it to fall over during linting (example output below). This is a dealbreaker for many, as lint is an important tool for catching issues and can also double back as a data generator for scripting tools (like removing unused resources).

An ideal solution would probably be a recompiled version of the linter with an updated Lombok dependency that supports Java 8.

A possible alternative could be adding a rule to somehow skip LambdaExpression nodes in the AST during processing, though I think this would come at the expense of knowing anything inside the lambda.

Example output of the exception encountered:

This workaround does not fixes false-positives on Android Studio which has bundled lombok jar.

I also think that Timber has custom lint rules that are using the old format. (Haven’t checked it though)
