title: Eclipse always Building workspace
body: <p>Normally when we check Project->Build automatically, it will build when our project's source has change, But when i check this option my eclipse is always building-- about every 2 or 3 seconds-- no matter it has changes or not. I can see from the right bottom state bar show "building workspace...".</p>
  
  <p>It's annoying that this behavior drive my eclispe really slow and the CPU is always in high usage.</p>
  
  <p>I'm using eclipse 3.7 for java EE developers, m2e, maven integration for WTP, git plugin, subclipse and Google plugin for eclipse, checkstyle, findbugs, etc.</p>
  
  <p>Any ideas?</p>
  
  <p>P.S I'm on Win 7 with 8GB RAM</p>
