I've got a big multi-module project, and I'd like to generate a report that shows all the licenses of all the things the project depends on.
I looked at tattletale, but it doesn't seem to do the trick. And I can easily find a plugin that will squirt a license into the top of each source file, but this exact thing is defying my googling.
The Maven Project Info Reports Plugin can be used to generate a Project Dependencies report that lists all dependencies and also groups them by licenses.
The project-info-reports:dependencies
goal can be used to generate an individual report but it should be used as a Maven report and is actually provided by default (see Configuring Reports) when generating the site for the project in the test
scope.
For an example, have a look at the Licenses of the Project Dependencies of the Maven Site Plugin.
