title: ${path.separator} in Maven on Mac is set to ":"
body: <p>We have a problem with several people using Windows and Maven, and I suspect the issue is with the <code>${path.separator}</code>. They get an error that a directory "D:\basedir\target/dist" does not exist. We don't get this error on Mac, Linux, and Unix systems. </p>
  
  <p>I'd like to change this to be <code>${project.build.directory}${path.separator}dist</code>, but on a Mac, the value of <code>${path.separator}</code> is <code>:</code> and not <code>/</code>. Now my build is failing on Macs because <code>/Users/david/project/target:dist</code> isn't a valid directory.</p>
  
  <p>How can I set my default <code>${path.separator}</code> on the Mac to be <code>/</code>?</p>
