Why Maven is not showing in IntelliJ?

In the file menu select settings -> plugins. search for maven, select maven, select enable. Restart intellij. Once restarted you will now have the option to start new maven project and maven functionality will be accessible in all your previous projects.

Why POM is ignored in IntelliJ?

The root cause was that the pom. xml file was ignored (Settings - Build, Execution, Deployment - Maven - Ignored Files). Thus, updates to this file pulling in a new version of a dependency did not trigger anything meaningful in IntelliJ IDEA (causing compilation issues).

Seems images are better way to answer this question.

  1. Projects are greyed out when you ignore them in your IntelliJ workspace.

Ignored Projects

  1. To add those projects or modules back in your workspace, right click on them and click on unignore projects as shown in below screenshot.

Ignored Projects back in Workspace

  1. Alternatively, you can also go to File - Settings -> Build, execution and deployment -> Build Tools -> Maven -> Ignored Files, now select whichever projects/modules you may wish to retain in your IntelliJ workspace.

Right click on the pom -> maven -> unignore. Then right click on pom -> maven -> reload project.

Seems some kind of bug when you open a child subdirectory then open the parent in IntelliJ.
