title: How do I open a Java project (that uses maven) in Eclipse? (Do I use M2E or maven-eclipse-plugin)
body: <p>I'm trying to <a href="https://github.com/p2abcengine/p2abcengine" rel="nofollow">open this project</a> in Eclipse but not sure how.</p>
  
  <p>I followed the <a href="https://github.com/p2abcengine/p2abcengine/wiki/How-to-Build-the-ABC-Engine" rel="nofollow">build instructions</a> and not sure how I tell Eclipse to use Maven as the source control (if required) and then open the Java project so I can step through it.</p>
  
  <p>I discovered that there are <a href="http://maven.apache.org/eclipse-plugin.html" rel="nofollow">two Maven plugins for Eclipse</a> (M2E and maven-eclipse-plugin) and not sure which one to choose, since they are incompatible with each other and I need to use.</p>
