This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
When using the javadoc goal to aggregate documentation using configured source directories there is the problem that also a reference to projects that are mentioned in the source directories is required. This adds a new (configurable) injector that adds the projects mentioned as the source as dependencies of the project.
