title: Cannot make gwt:compile work for a GWT application
body: <p>When running <code>gwt:compile</code> my application is throwing this error:</p>
  
  <blockquote>
    <p>[INFO]    at com.google.gwt.dev.Compiler.main(Compiler.java:127) [INFO]

  <p>I can't seem to find the root cause of this error, what could be causing this? And what is this "Is the source glob too strict?"</p>
  
  <p>Using maven and GWT 2.7.0</p>
