Add the groovy plugin for eclipse,
In eclipse's Help -> Install New Software, add the groovy download link:
http://dist.springsource.org/milestone/GRECLIPSE/e4.4/, the above address corresponds to the luna plug-in, if you want the corresponding eclipse plugin, you need to go to https://github.com/groovy/groovy-eclipse/wiki (this URL) to find the address.
Then after selecting all, start downloading, after downloading, restart eclipse, then clean the project and you are done.
