title: How repair/recreate Eclipse workspace and/or Maven caches/repositories?
body: <p>I was creating some Maven project under Eclipse with using <code>spring-osgi-bundle-archetype</code> and this causes some plugins etc to download, which have frozen. After I killed Eclipse, many things related to Maven started to cause errors (Unable to download source code, Unable to find artifacts etc, without any apparent reason).</p>
  
  <p>Looks like something was damaged in Eclipse cache or something.</p>
  
  <p>How to clean and rebuild ALL which is possible in the situation?</p>
  
  <p>Deletion of <code>core.eclipse.m2e.*</code> folders from workspace's <code>.metadata</code> folder didn't help.</p>
