Why would IntelliJ be displaying an old version of a library that's no longer used by direct or transitive dependencies (under "External libraries")? It persists after doing a restart and rebuild, and refreshing Maven indices. 😞

[Chris Lee]

does that library show up in a Gradle build scan?

[Richard Gomez]

Only the new version shows up when I do mvn dependency:tree or other related commands (not sure if Gradle build scan is something I can run separately).

[Richard Gomez]

Hmm, interestingly it's showing two types of libraries. One is just the jar file, and the other is the actual "maven" resource. Perhaps some strange scenario lead to the jar files being permanently added to the library settings?

[Chris Lee]

perhaps some of those are annotation processors or similar, in a different scope. not that familiar with Maven on how to get the right info out for those.

[Richard Gomez]

That could also explain why I've been seeing test dependencies and IntelliJ internals show up as suggestions. 🤔

[Richard Gomez]

I am not quite sure myself. I am going to try manually deleting everything from the library settings and see what happens. ¯\_(ツ)_/¯

[Chris Lee]

is it possible those JARs are in a directory that IntelliJ has been configured to have as a module?

[Alexey Belkov [JB]]

Try to remove .idea directory and reimport / reopen the project.

[Richard Gomez]

That worked. When in doubt, rm -rf and try again. 🙂

[Richard Gomez]

Thanks for the suggestions Chris & Alexey.

Fyi a good alternative is git clean -fxdn which will list all non-tracked files to delete. Then if all looks good, git clean -fxd to remove them. This is basically a clean git clone that leaves all your local branches but clears IJ, build and Gradle stuff
