Handle different language and target levels for sources and tests with IntelliJ IDEA

Question

I\'m interested if someone has clue how to handle this pom in projects properties of IDEA:

   org.apache.maven.plugins

As already mentioned different language levels for main and test sources are not yet supported by Idea.

There's a workaround to force Idea to use the language level defined in testSource when importing Maven project. You can create a separate Maven profile only for Idea with different compiler plugin settings:

    
        default
        
            true
        
        
            
                
                    org.apache.maven.plugins
                    maven-compiler-plugin
                    3.2
                    
                        1.6
                        1.6
                        1.8
                        1.8
                    
                
            
        
    

    
        ide
        
            false
            
                idea.maven.embedder.version
            
        
        
            
                
                    org.apache.maven.plugins
                    maven-compiler-plugin
                    3.2
                    
                        1.8
                        1.8
                        1.8
                        1.8
