Question

when I try to use the @Data annotation with lombok 0.10.1. in Eclipse: 3.7.0.v20110504-0800-7b7qFVpFEx2XnmYtj_9RfO7

I got this error, can anyone advise?

The cause of this problem is that that version of lombok used java6 API, and I suppose you’re using java5 to run eclipse. This has been fixed in the 0.10.4 release. The current version is 0.10.6.
