title: wro4j & m2e Eclipse not compiling LESS
body: <p>I am trying to setup my developer env so that I can use maven to compile my LESS files for formal builds, but also have Eclipse compile the LESS for incremental builds so I dont have to keep kicking of maven tasks every time I make a LESS change.  Having looked around - it seems like wro4j &amp; the maven plugin &amp; the m2e-wtp plugin should provide all that.</p>
  
  <p>My setup is as follows: I have just installed the latest stable Eclipse (Java EE package, that includes the WTP stuff - v4.3) and I have installed the m2e plugin and the m2e-wtp plugins.</p>
  
  <p><strong>pom.xml:</strong></p>
  
  <pre><code>&lt;plugin&gt;
      &lt;groupId&gt;ro.isdc.wro4j&lt;/groupId&gt;
      &lt;artifactId&gt;wro4j-maven-plugin&lt;/artifactId&gt;
      &lt;version&gt;1.4.5&lt;/version&gt;
      &lt;executions&gt;
          &lt;execution&gt;
              &lt;phase&gt;compile&lt;/phase&gt;
              &lt;goals&gt;
                  &lt;goal&gt;run&lt;/goal&gt;
              &lt;/goals&gt;
          &lt;/execution&gt;
      &lt;/executions&gt;
      &lt;configuration&gt;
          &lt;targetGroups&gt;roa-all&lt;/targetGroups&gt;
          &lt;destinationFolder&gt;${project.build.directory}/${project.build.finalName}&lt;/destinationFolder&gt;
          &lt;cssDestinationFolder&gt;${project.build.directory}/${project.build.finalName}/css/&lt;/cssDestinationFolder&gt;
          &lt;jsDestinationFolder&gt;${project.build.directory}/${project.build.finalName}/js/&lt;/jsDestinationFolder&gt;
          &lt;wroManagerFactory&gt;ro.isdc.wro.maven.plugin.manager.factory.ConfigurableWroManagerFactory&lt;/wroManagerFactory&gt;
      &lt;/configuration&gt;
  &lt;/plugin&gt;

  <p><strong>wro.properties:</strong></p>
  
  <pre><code>preProcessors=cssImport,semicolonAppender   
  postProcessors=lessCss,cssMinJawr
  </code></pre>
  
  <p><strong>wro.xml:</strong></p>
  
  <pre><code>&lt;groups xmlns="http://www.isdc.ro/wro"&gt; 
    &lt;group name="roa-all"&gt;
          &lt;css&gt;/less/*.less&lt;/css&gt;
      &lt;/group&gt;      
  &lt;/groups&gt;
  </code></pre>
  
  <p>Inside my <code>/less/</code> folder are basically a few css files that I have renamed .less files, and one where I have actually added some LESS syntax with a few colour variables set.  This mostly works, as I make changes to my LESS, the plugin detects and rebuilds my uber css file, however, rather critically, it doesn't seem to be compiling the LESS - it combines the files, and minifies, but my <code>@variables</code> are all still in LESS syntax.</p>
  
  <p>I also noticed that the maven plugin was up to v 1.7.0 so tried upgrading to that to see if that was the problem, but that just does nothing at all (nothing gets built at all and I have no uber css etc)</p>
  
  <p>Anyone had any experience setting this up or know anything I have missed in the setup?</p>
