title: Maven release plugin with git + developer connection
body: <p>I am trying to use maven release plugin for creating a branch from trunk.</p>
  
  <p>Ex. repository.git/
                   child1/
                   child2/</p>
  
  <p>The plugin creates a new branch that contains my entire repository.
  How can i restrict it to create a branch that contains only child1 ?</p>
  
  <p>Currently the pom.xml connection, developer connection and url are as follows :</p>
  
  <pre><code>&lt;scm&gt;
    &lt;connection&gt;scm:git:ssh://githost/repository.git&lt;/connection&gt;
    &lt;developerConnection&gt;scm:git:ssh://githost/repository.git&lt;/developerConnection&gt;
    &lt;url&gt;scm:git:ssh://githost/repository.git&lt;/url&gt;
    &lt;tag&gt;HEAD&lt;/tag&gt;
  &lt;/scm&gt;
  </code></pre>
  
  <p>In svn we used to achieve this by using the absolute path to child1 in developerConnection.</p>
  
  <p>Thanks,</p>
