There is a solution similar to @s1moner3d answer which doesn't require changes to pom.xml file.

Go to Window -> Preferences -> Maven -> Lifecycle Mappings and click on the Open workspace lifecycle mappings metadata

Than add "pluginExecution" entry like in the code below. If the file is empty, copy the entire content below. You might need to change "versionRange".

  
    
      
        org.apache.maven.plugins
        maven-dependency-plugin
        2.10
        
          copy-dependencies
        
      
      
        
      
    
  

In order for this to take effect go back to Preferences and click Reload workspace lifecycle mappings metadata. Update maven projects and / or rebuild. The error should be gone.

Useful if you cannot or don't want to modify pom.xml for any reasons but want to stop your eclipse m2e from executing particular goal of a particular plugin.
