I have a Maven project multiple people work on. Some classes and a new dependency were added in the last iteration. In the new classes, my IDE is marking the new imports that belong to the new dependency with "Cannot resolve symbol ''". The other people working on this exact same project don't have problems with the new dependencies at all. I'm not able to build it.
I'm using IntelliJ IDEA Community Edition.
I did a "mvn clean install" sometimes this solved the issue. But it didn't change anything. I did a "Invalidate Caches/Restart" in my IDEA. I removed the ".idea" folder and let IDEA recreate it. I removed the "system" folder of IDEA in "C:\Users<my name>\AppData\Local\JetBrains<IDEA version>" and let IDEA recreate it. I asked the other people working on this project and they also did not see any error.
I did a rebuild / tried running the application. The error was "java: package does not exist"
Also in the Project Settings tab, the libraries of Maven are not visible.
Are there any other suggestions, what I could do in order to solve this problem?
