title: maven exec plugin - <commandlineArgs> doesn't work as expected
body: <p>I use maven exec plugin and want to execute simple .exe file with an argument passed in, so the final command line execution would look like:</p>
  
  <pre><code>ISCC.exe setup.iss
  </code></pre>
  
  <p>I tried to use </p>
  
  <pre><code>&lt;arguments&gt;
     &lt;argument&gt;arg1&lt;/argument&gt;
    ...
  &lt;/arguments&gt;
  </code></pre>
  
  <p>however it produced output that was not suitable for me:</p>
  
  <pre><code>ISCC.exe, arg1, arg2, arg3 
  </code></pre>
  
  <p>because I didnt want to have commas and wanted to have just spaces instead so decided to use  <code>&lt;commandlineArgs&gt;</code></p>
  
  <p>and finally my build tag is as follows:</p>
  
  <pre><code>&lt;build&gt;
          &lt;plugins&gt;
              &lt;plugin&gt;
                  &lt;groupId&gt;org.codehaus.mojo&lt;/groupId&gt;
                  &lt;artifactId&gt;exec-maven-plugin&lt;/artifactId&gt;
                  &lt;version&gt;1.5.0&lt;/version&gt;
  
                  &lt;executions&gt;
                      &lt;execution&gt;
                          &lt;goals&gt;
                              &lt;goal&gt;exec&lt;/goal&gt;
                          &lt;/goals&gt;
                          &lt;phase&gt;install&lt;/phase&gt;
                      &lt;/execution&gt;
                  &lt;/executions&gt;
                  &lt;configuration&gt;
                      &lt;executable&gt;ISCC.exe&lt;/executable&gt;
                      &lt;commandlineArgs&gt;
                          setup.iss
                      &lt;/commandlineArgs&gt;
                  &lt;/configuration&gt;
              &lt;/plugin&gt;
          &lt;/plugins&gt;
      &lt;/build&gt;
  </code></pre>
  
  <p>but when I run maven, it produces the command line execution just as it was previously:</p>
  
  <pre><code>ISCC.exe, setup.iss
  </code></pre>
  
  <p>i.e. with comma instead of space</p>
  
  <p>Could you please give a hint of how to fix this,</p>
  
  <p>Cheers</p>
