Cannot add Groovy code to an existing Maven Java project "def cannot be resolved to a type"

This might be something very simple but I cannot seem to get it right. I have a Spring MVC 3.0 application and I would like to use some groovy code.

Problem

When I add Groovy code (Groovy Classes) and I start defining my variables the IDE (SpringSource Tool Suite in my case) tells me "def cannot be resolved to a type"

What I have done

  1. Created a source folder named src/main/groovy
  2. Created a .groovy Class added a method with def msg = 'Hello'
  3. Added Groovy libraries to Classpath
  4. Did a Project/Clean through the IDE
  5. The IDE (STS) still tells me "def cannot be resolved to a type"

If I create a simple Groovy Project I can interchange groovy/java with no problem but now that I am adding Groovy to something that I already had it does not seem to be picking up that I am trying to do groovy in those groovy files. I have Groovy on the classpath, Groovy nature and everything. Not sure what else to do so that STS stops flagging my groovy code as errors.

Thanks.

  1. Ensure you have Groovy installed (yum, aptitude, etc).
  2. Right click your project.
  3. Select "Groovy" -> "Add Groovy libraries to classpath" The project should automatically rebuild and the problem is resolved.

You have to install a Groovy Eclipse plugin.

Open you Dashboard, click on "Extensions" tab (of the Dashboard), check the "Groovy Eclipse" option:

enter image description here

and click install.

Once it is installed, it'll ask you to restart Spring Tool Suite => do it.

Then right click on your project => "Configure" => "Convert to Groovy Project"
