What I want to do is invoke maven from a groovy script. The groovy script in question is used as a maven wrapper to build J2EE projects by downloading a tag and invoking maven on what was downloaded.

Select the trigger Genius Commit created (from the DevOps category). Choose the command Run code, and click Save. Click New action. Select the action Run Groovy script.
parse the source files. depending on the implementation, create stubs that are compatible with the Java compiler. invoke the Java compiler to compile the stubs along with Java sources – this way Java classes can find Groovy dependencies. compile the Groovy sources – now our Groovy sources can find their Java ...
The simplest way to invoke an external process in Groovy is to use the execute() command on a string. For example, to execute maven from a groovy script run this:
"cmd /c mvn".execute() If you want to capture the output of the command and maybe print it out, you can do this:
print "cmd /c mvn".execute().text The 'cmd /c' at the start invokes the Windows command shell. Since mvn.bat is a batch script you need this. For Unix you can invoke the system shell.
