mvn eclipse not recognizing src/main/groovy as the source folder

Question

I always have to configure the groovy folders in Eclipse even after I've generated the eclipse project in maven using mvn eclipse:eclipse as shown below. Is there a way to tell maven to treat these folders as source folders automatically when generating the eclipse project?

My plugin definition. I am using Groovy-Eclipse compiler plugin for Maven
