This Eclipse error simply means that the m2e Eclipse plugin does not know how to map "significant" events in the IDE (like clean project, saving files, etc.) to the goals defined by the plugin. For example, when you save the pom.xml file, the m2e plugin re-builds the project. If you do a "quick fix" (ctrl-1) on the error, you can permanently mark the goal as ignored in your Eclipse build. Eclipse does this by adding a section to your pluginManagement inside your pom.xml. This means that Eclipse will not attempt to run any goals in this plugin, and you will have to do it outside of the Eclipse environment.
