title: Spring Source Tool Suite Roo problem
body: <p>I'm very new in spring and have just downloaded sts 2.7.2 and installed it with roo.
  <em>It's possible to open roo shell for projects, but impossible to use roo commands, because they all return only "null" value. What's wrong?</em>
  It's possible to use roo started from 'bin/roo.sh'.
  I've added roo folder path to 'window/preferences/spring/roo support'.</p>
