I have a maven project. Whenever I try to open it in IDEA, all plugins are shown twice in the tree. I have tried restart, invalidate caches / restart, checkout project again, clear .m2 folder, checking maven settings file.
IntelliJ IDEA 2019.3.2 ( Community Edition ) Build #IC-193.6015.39, built on January 21, 2020
Runtime version: 11.0.5+10-b520.30 amd64
I couldn't find any solution. Thanks for help.
There are three immediate things that you could try, that could help:
Reimport the maven project. IntelliJ tries to parse your pom and build an object model based on the information found in the pom. There is a button that looks like two arrows that form a circle in the maven tab.
Close the project and open up the pom.xml again (its important, not the .idea or something, but a pom.xml). It will offer you to delete the current definitions and create new. Do it and it will rebuild everything.
File --> Invalidate Caches --> Restart. It will invalidate intelliJ caches (obviously) and restart the IDE.
