title: mvn dependency:copy-dependencies removes the versions
body: <p>I'm using "mvn dependency:copy-dependencies" to get all sources of the dependencies my project uses.
  I use it from command line, so it looks like this: </p>
  
  <pre><code>mvn dependency:copy-dependencies -Dclassifier=sources -DincludeScope=compile
  </code></pre>
  
  <p>It works fine except of a small problem: For some reason the version is removed by this plugin. So instead of commons-logging-1.1.1-sources.jar, I'm getting commons-logging-sources.jar</p>
  
  <p>The documentation says that "stripVersion" argument should effect this behavior, but the default value is false. Moreover, I tried to set it explicitly and it didn't help.</p>
  
  <p>I'm using apache-maven-2.2.1 with jdk1.6.0_21</p>
  
  <p>Thanks,
  Tarlog.</p>
