title: no any "plugin descriptor" founded in my maven project
body: <p>I am wanting to create UI with qt-jambi, but i have a problem.
  i am using maven in eclipse, and create a maven project, and i downloaded and installed 3rd party qt-jambi jar files in my local repository from here:
  <a href="http://old.qt-jambi.org/maven2/net/sf/qtjambi/" rel="nofollow">http://old.qt-jambi.org/maven2/net/sf/qtjambi/</a>
  and below files:</p>
  
  <p>(1) <a href="http://old.qt-jambi.org/maven2/net/sf/qtjambi/qtjambi-maven-plugin-linux32/4.5.2_01/" rel="nofollow">qtjambi-maven-plugin-linux32-4.5.2_01.jar</a></p>
  
  <p>(2) <a href="http://old.qt-jambi.org/maven2/net/sf/qtjambi/qtjambi-platform-linux32/4.5.2_01/" rel="nofollow">qtjambi-platform-linux32-4.5.2_01.jar</a></p>
  
  <p>i am using ubuntu 12.10(32bit) and Maven 3.0.4.</p>
  
  <p>My maven repository(m2 home)path for qt-jambi is like below:</p>
  
  <pre><code>/home/mehdi/.m2/repository/net/sf/qtjambi/qtjambi/4.5.2_01/qtjambi-4.5.2_01.jar
  /home/mehdi/.m2/repository/net/sf/qtjambi/qtjambi-maven-plugin-linux32/4.5.2_01/qtjambi-maven-plugin-linux32-4.5.2_01.jar
  </code></pre>
