You can go to Preferences -> Build, Execution, Deployment -> Build Tools -> Maven -> Importing and check the box that says Import Maven projects automatically.

In Mac, you can do Command + Shift + A, then enter the action reimport, then click on Reimport all Maven projects.

March 29, 2012 - I also had this problem, I tried everything mentioned here, but they did not work!! the issue was that in maven projects section, my maven projects were ignored for some reason!!So I just right clicked on each project and clicked unignore project!!after that I did everything mentioned here and it worked ... @Jmeen011 Your answer worked for me, I simply had to do invalidate caches and restart for intelliJ to reinsert all my dependencies.

June 2, 2019 - Seems to me that the libraries folder in .idea just never updated. Hope this helps someone ... The only way to make it work is to perform a maven build outside of IntelliJ and then it works.

Hello Andrey Dernov That was an excellent suggestion! I disabled the Scala plugin, then deleted both .idea directory and .iml file and after I recreated all the project from the existing sources. It worked. I have now the right Spring Boot dependencies in the « External Libraries » section of the project.

April 27, 2021 - My maven project has a dependency on a jar in the local maven repository. I updated the version in the pom file, but the version brought into the project stayed the old version. When I decompiled the class I found the path was to the old version. After investigation the problem was that the version of the jar in .idea/libraries was still referring.
