Since the license plugin for maven is configured with the generated POM file, you need to apply license file headers (mvn initialize license:format) before running mvn install.
Maven Settings
To run the short form of commands shown in this usage scenario, the plugin group de.smartics.maven.plugin needs to be registered in the Maven Settings file.
You'll also need to manually install the projectdoc artifacts to your local artifact repository. This may be an internal artifact server.
To actually compile and start the project, you need to have the references artifacts on your artifact repository. Access to Atlassian's artifacts should already been configured when you have installed the Atlassian SDK.
You need to download the projectdoc artifacts and install them manually since they are currently not available on a public repository.
