title: Android APK file and DEX files not created, with no warning or error
body: <p>I've developed Android for a while now, using WIN7 64bit and Eclipse.
  Since I've tried to install the new ADT (1.5), I get a very weird phenomena. My build doesn't complete, and doesn't generate the APK file, nor the dex files.
  the class files are created, but nothing else.</p>
  
  <p>Also, there is no warning or error neither at the output or the Eclipse log.</p>
  
  <p>The problem didn't occur immediately, but only after 1 or 2 good builds.
  Even if I create a simple project, the same thing happens.</p>
  
  <p>I didn't find anything useful on the net.
  I've re-downloaded Eclipse, the SDK, ADT, and started all over again, and got the JRE7 compatibility issue (function ... must override).
  I guess I got a Java SE update, and lost the old JRE. So I've downloaded JRE6, changed the compliance issue, and set it and the environment, and got back to square 1 :)</p>
  
  <p>The build process starts, reaches 50% or 75%, suddenly stops, and no apk or dex files are created.
  Even for new empty helloWorld projects.</p>
  
  <p>Can someone please help? I have no idea how to proceed.</p>
  
  <p>Thanks</p>
