If you’ve configured your Maven
settings.xml or other build tool configuration to use the
group as a mirror for all repositories, you might encounter projects that are unable to retrieve components from
your local repository manager installation.
This usually happens because you are trying to build a project that has defined a custom set of repositories and snapshot repositories or relies on the content of other publically available repositories in its configuration. When you encounter such a project all you have to do is
- add this repository to your repository manager as a new proxy repository
- and then add the new proxy repository to the public group.
The advantage of this approach is that no configuration change on the build tool side is necessary at all.
