title: On Intellij 13, executable jar created is invalid or corrupted
body: <p>I tried to create an executable jar from my project on Intellij 13 (win8), following these answers <a href="https://stackoverflow.com/questions/1082580/how-to-build-jars-from-intellij-properly">How to build jars from IntelliJ properly?</a> and execute the jar created, then I get "Error: Invaid or corrupt jarfile" followed by the path of the jar.</p>
  
  <p>My project is simple, but have multiple java files and an UI form.</p>
  
  <p>I call <strong>Build|Build Artifacts|Jar</strong> after create jar artifact on <strong>Project Structure|Artifacts</strong>, after build.</p>
  
  <p>I created the project with a maven scafold, but there are no dependencies on pom.xml.</p>
  
  <p>I'm using java7.
  Is something missing?</p>
