Adding a local repository to your virtual P2 repository does not require any special configuration:
Simply select the desired local repository from the Local Repository field. Usually, this will be either a Maven or a Generic repository.
In the Path Suffix field, specify the path to the P2 metadata files (
content.jar, artifacts.jar, compositeContent.xml
etc.). If left empty, the default is to assume that the P2 metadata files are directly in the repository root directory.Click Add.
If you have a Tycho repository deployed to a local repository as a single archive, specify the archive's root path. For example: eclipse-repository.zip!/
