Answer 1

In my case the error was: CoreException: Could not calculate build plan: Plugin org.apache.maven.plugins:maven-compiler-plugin:2.3.2 ....

With eclipse luna from console in the pom.xml folder

mvn clean
mvn install

With Juno I had to had this to my pom.xml

  
    
      
        
          org.apache.maven.plugins
          maven-compiler-plugin
          2.3.2
          
            
          
        
      
    
  

And then

mvn install

And then from eclipse right click>maven>update project * Once the plugin is donwloaded you can remove the plugin from your pom.xml
