How do I develop a maven plugin using Groovy in Eclipse

I want to write a Maven plugin in Groovy, but under Eclipse (Galileo).

• I've downloaded and installed Groovy-Eclipse plugin
• I've created my very simple POM file (included below).
• I've created a simple Echo mojo and place it under "/src/main/groovy/com/acme/maven/plugins/foo".
• I performed "Import Existing Maven Project" in Eclipse (using M2Eclipse plugin).

The problem is that I don't see "src/main/gro开发者_运维技巧ovy" as a source folder, which makes it hard to develop: - I have to create the package directory structure (com/acme/maven/plugins/foo) manually - Refactoring probably won't work easily - Incremental probably won't work.

How do you guys develop your Maven plugins using Groovy in Eclipse?

You should definitvly install the Groovy-Eclipse plugin if you plan to develop Groovy code in Eclipse. You can find all the details here:

http://groovy.codehaus.org/Eclipse+Plugin

You should also add the Groovy Maven Plugin to your pom.xml like this (see this page for details):

<build>
  <plugins>
    <plugin>
      <groupId>org.codehaus.groovy.maven</groupId>
      <artifactId>gmaven-plugin</artifactId>
      <executions>
        <execution>
          <goals>
            <goal>generateStubs</goal>
            <goal>compile</goal>
            <goal>generateTestStubs</goal>
            <goal>testCompile</goal>
          </goals>
        </execution>
      </executions>
    </plugin>
  </plugins>
</build>

Now update your Eclipse project configuration via Right-click on project -> Maven -> Update project configuration. Now you should see that the src/main/groovy folder has been added to the source folders.

Use GMaven and the eclipse plugin as suggested by chkal.

In addition to GMaven, and Groovy-Eclipse, there is m2eclipse support for Groovy-Eclipse that should be installed separately. Go to the Groovy-Eclipse snapshot update site:

http://dist.codehaus.org/groovy/distributions/greclipse/snapshot/e3.6/

And install the feature from there. This feature will ensure that your groovy/maven projects are set up correctly when they are imported.
