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

Question

I have a fairly simple Maven project:

    
        ...
    
         


        

Answer 1

I know this is old post but I struggled today with this problem also and I used template from this page: http://maven.apache.org/plugins/maven-dependency-plugin/usage.html

  [...]
  
    
      
        org.apache.maven.plugins
        maven-dependency-plugin
        2.7
        
          
            copy
            package
            
              copy
            
            
              
                
                  [ groupId ]
                  [ artifactId ]
                  [ version ]
                  [ packaging ]
                   [classifier - optional] 
                  [ true or false ]
                  [ output directory ]
                  [ filename ]
                
              
              
            
          
        
      
    
  
  [...]

and everything works fine under m2e 1.3.1.

When I tried to use

    
        
            org.apache.maven.plugins
            maven-dependency-plugin
            2.4
            
                
                    copy-dependencies
                    package
                    
                        copy-dependencies
                    
                    
                        ${project.build.directory}/dependencies
                        
                
            
        
    

I also got m2e error.
