title: Maven assembly plugin: run only one descriptor
body: <p>I have a project which has several custom descriptors written for the assembly plugin. Is there a way to run only one of those descriptors at a time instead of the whole bunch? I tried using the descriptors switch as documented <a href="http://maven.apache.org/plugins/maven-assembly-plugin/assembly-mojo.html" rel="nofollow noreferrer">here</a>, passing in the full path to the one descriptor that I wanted to run, but instead it's running all of the descriptors in my app's main pom file, seeming to ignore the switch I specified.</p>
