IntelliJ is not recognizing Maven Dependencies

I have a Spring Project in which I am using Maven to manage my dependencies. I have some (5 to 10) packages mentioned inside the POM-File and Maven is successfully downloading them into my local repository.

But IntelliJ is not recognizing these packages. Not even the SpringBoot-Packages.

I have tried different things:

  • Delete local Maven-Repository
  • Create a new Project inside IntelliJ from existing Sources but with the same Directory as the original Project
  • Create a new Project inside IntelliJ from existing Sources but I have copied the src-Folder and the POM-File to a new Directory first

Why is IntelliJ not recognizing the Maven-Dependencies?

P.S.: The Maven-Build is successful. So Maven IS recognizing the packages inside the repository.

IntelliJ seems to handle an Index for all dependencies inside the project. And this Index was not correctly handled in my case by IntelliJ.

But I found out that I can manually clear this cache/index by using following function:

File > Invalidate Caches / Restart...

In case that the problem still exists after File > Invalidate Caches / Restart... (as suggested by @Snickbrack), reload the maven projects by Maven > Reload all maven projects.

Just open maven pom.xml as project instead of creating new project from sources

Please run the command mvn idea:idea it will work.

Please check the maven home path by following the steps below:

  1. Select the project in Project window >> File >> settings>> Build,Execution,Deployment >> Maven
  2. Check the 'Maven home path' as per Maven installation location. It will download all the dependencies.
