I am using Apache commons-configuration2 in one of my projects. Recently, I decided to let Maven manage my projects. Which works fine, except for commons-configuration2; I am not able to find that dependency on the Maven repo. Even when looking just for commons-configuration, not commons-configuration2, none of the results I am getting are org.apache.commons.
What am I doing wrong?
That's because, version 1.x of the artifact commons-configuration was really under the commons-configuration group. You can find the latest release version, 1.10, of that artifact in the repo.
It was only after it became commons-configuration2 (technically an entirely different Maven artifact of the same project), it was grouped under org.apache.commons. You don't see them in the maven repo (the RELEASE repo that is) probably because it's still a SNAPSHOT. You can still find the artifact in the SNAPSHOT repo.
See the project summary and release history for more information.
