maven-dependency-plugin (goals “copy-dependencies”, “unpack”) is not supported by m2e

Question

I have a fairly simple Maven project:

    
        ...
    
         


        

Answer 1

It seems to be a known issue. You can instruct m2e to ignore this.

Option 1: pom.xml

Add the following inside your tag:

    
    
        org.eclipse.m2e
        lifecycle-mapping
        1.0.0
        
            
                
                    
                    
                        
                            org.apache.maven.plugins
                            maven-dependency-plugin
                            [1.0.0,)
                            
                                copy-dependencies
                            
                        
                        
                            
                        
                    
                
            
        
    
   

You will need to do Maven... -> Update Project Configuration on your project after this.

Option 2: Global Eclipse Override

To avoid changing your POM files, the ignore override can be applied to the whole workspace via Eclipse settings.
