Plugin execution not covered by lifecycle configuration error in Eclipse Juno

Question

Why does my Maven build work perfectly fine on the command line but when I run in Eclipse, it requires I add this section to my pom.xml, otherwise I get this error:

<         


        

Answer 1

1. Help -> Install new Software

   • Install the Groovy Compiler 2.2 / 2.1 Feature

   • Install Groovy-Eclipse M2E integration

2. Window -> Preferences -> Maven -> Lifecycle Mappings -> Open workspace lifecycle mappings metadata

Add the following xml:

    
        
            
                org.codehaus.gmaven
                gmaven-plugin
                [1.3,)
                
                    compile
                    testCompile
                
            
            
                
            
        
    

3. Reload the Lifecycle Mappings and invoke a projekt update on your maven project. (ALT+F5)
