IntellijIDEA not recognizing classes specified in Maven dependencies

Question

I have a project in IntellijIDEA which was created with Maven. I then specified a set of dependencies and external repositories in the Pom.xml file.

The project builds

Answer 1

Looks like there are several, valid reasons why intelliJ would ignore a pom file. None of the previous answers worked in my case, so here's what did work, in case someone else runs into this issue:

In this example, module3 was being completely ignored by IntelliJ. The pom.xml in that directory wasn't even being treated as a maven pom.

My project structure is like this:

myProject
    module1
    module2
    module3

BUT, my (simplified) pom structure is like this:

    4.0.0
    devs
    myProject
    0.0-SNAPSHOT
    pom
    myProject

    
        module1
        module2
    

    
        
            CompleteBuildProfile
            
                module3
            
        
    

To fix this, I modified the root element to add in module3 temporarily.

    
        module1
        module2
        module3
    

Next re-import the root pom, and IntelliJ will add the module. When that's done, revert the pom. IntelliJ will ask if you also want to remove module3 from the project structure. Click No.

Bam! Done. Module3 works and I can run my Integration tests from IntelliJ again :D
