As a convenience to using the jython command, the maven-jython-plugin has a means of running the Jython shell. This is in further pursuit of allowing a user to get started running Jython immediately, without having to do a full local installation of the project.
In order to use the Jython shell, your project must be configured to use the maven-jython-plugin. If it is not already, please review the sections on common setup in the usage guide .
Once setup, you can start an interactive Jython shell by executing the following from a system shell in your project's directory:
mvn jython:shell
Maven will fetch any necessary dependencies and when all done, you'll have an interactive Jython shell to play around with.
