Do I need to pre-create a maven_install.json file? I assumed it generates one for you. Am I missing something?

We expect the command to go through and generate a maven_install.json file.

A maven_install.json needs to be created manually and only then will it be updated with the full list of packages and their versions as clarified in the following trouble ticket:
