This is a very small fork of lombok.ast as some Android tools needed a few modifications. The normal repository for lombok.ast is here https://github.com/rzwitserloot/lombok.ast and our changes for 0.2.3 are in this pull request: https://github.com/rzwitserloot/lombok.ast/pull/8

The newest version!
