If you’ve configured your Maven
settings.xml or other build tool
configuration to use the Nexus
public repository group as a mirror
for all repositories, you might encounter projects that are unable to
retrieve artifacts from your local Nexus 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 Nexus 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.
