  <p>I already installed SVN client with SlikSVN-1.6.1 and mvn-3.0.4 and checked the installed commands in command prompt of Maven-slave machine. </p>
  
  <p>I tried to do "Perform maven release" with dry-run via command prompt on Maven-slave directly. The result is work!!.</p>
  
  <pre><code>&lt;plugin&gt;
      &lt;groupId&gt;org.apache.maven.plugins&lt;/groupId&gt;
      &lt;artifactId&gt;maven-release-plugin&lt;/artifactId&gt;
      &lt;version&gt;2.4&lt;/version&gt;
  &lt;/plugin&gt;
  </code></pre>
  
  <p>Maven-release-plugin version in POM.xml is 2.4.0.</p>
  
  <p>This problem is occurred in Windows7 of Maven-slave machine but WindowsXP isn't founded even thought the versions of SVN client and mvn between both machines are same.</p>
  
  <p>What could be cause of this, and how do I fix it?</p>
