title: Correct way to remove plugin from Eclipse
body: <p>Last times, I'm facing problem of removing plugins from Eclipse.</p>
  
  <p>symptoms:</p>
  
  <p><strong>1.</strong> if removing thru <em>already installed</em> menu,that can't reinstall correctly and have several perspectives - e.g. for SQL Explorer. (in <code>Open Perspective</code> menu)</p>
  
  <p><strong>2.</strong> if removing thru file system - manually from <code>plugins</code> directory,that I'm not certain about what .jars should I remove</p>
  
  <p>The question is, what are the steps that guarantee <strong>correct full</strong> removing of plugin and what is better, manual or automatic removing?</p>
  
  <p>Share,please,your experience.</p>
