gmaven-archetype-mojo Archetype

To help get Groovy plugins started faster, you can use the gmaven-archetype-mojo. This will create a new project with the basic POM configuration and an example Groovy-based Mojo class to get you started quickly:

mvn archetype:generate -DarchetypeGroupId=org.codehaus.groovy.maven.archetypes -DarchetypeArtifactId=gmaven-archetype-mojo

To use a specific version of an archetype specify -DarchetypeVersion=<VERSION>.

The Maven Archetype Plugin will ask a few questions about your new project:

The above example would have created the following project structure:

example-maven-plugin
example-maven-plugin/pom.xml
example-maven-plugin/src
example-maven-plugin/src/main
example-maven-plugin/src/main/groovy
example-maven-plugin/src/main/groovy/org
example-maven-plugin/src/main/groovy/org/mycompany
example-maven-plugin/src/main/groovy/org/mycompany/myproject
example-maven-plugin/src/main/groovy/org/mycompany/myproject/example
example-maven-plugin/src/main/groovy/org/mycompany/myproject/example/HelloMojo.groovy

To build the new project simply change to the newly created project directory and run Maven:

cd example-maven-plugin
mvn install

The build output should look something like this:
