Intellij maven window missing

Question

My Intellij, 2020.1, and also till today 2019.3 has something weird with supporting maven.

Although I can create a new maven project, and get the maven tools window to be available at that project - some of my work related projects, fail to have maven tools enabled.

More details:

These projects have pom.xml at their root (I opened them from root). I am able to build these projects with command line mvn install. in Preferences > plugins: Maven is enabled. in Preferences > build tools > the configuration is like in the picture I attached. local maven reposistory is where I supplied

But:

Maven tools window is missing.

In Project structure > Modules > + > I can import all sorts of projects - but not maven.

Classes of maven dependencies appear "red" in the code, and I get no IntelliSense for them.

What am I doing wrong?

Answer 1

Most likely the project was not associated with Maven. In such cases opening pom.xml file explicitly would reimport the project and will fix the problem.

You can also try adding Maven support to the existing project.
