I upgraded recently to the new Eclipse version (Oxygen). I downloaded the lombok.jar from the website and installed it. This is how the eclipse.ini looks like a

I tried all this but it didn't work for me. Lombok libraries were still not adding into my classpath.

2.1.9.RELEASE
when I reduced this to following version which worked for me
2.1.7.RELEASE
