title: ArtifactDescriptorException: Failed to read artifact descriptor Maven error
body: <p>I am using the latest Eclipse for Java EE with JBoss Tools installed so Maven is included. I imported an existing Maven project to my workspace and tried to update the dependencies but I only get errors error in my POM that some argument is invalid and no artifact could have been transfered.
  There are actually two different errors and maybe they depend on each other?
  You can check: the server is available and I also tried to reinstall Eclipse and JBoss. So what else is missing?</p>
