title: Can't compile style.scss with sass-maven-plugin
body: <p>I would like to use sass-maven-plugin to compile some <code>SASS Template style.scss</code> into <code>css style.css</code>. I have added the plugin to my pom.xml build.plugins as it is descriped <a href="http://developer.jasig.org/projects/sass-maven-plugin/1.1.0/plugin-info.html" rel="nofollow">here</a>. My <code>pom.xml</code> looks like this:</p>
  
  <pre><code>&lt;project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    &lt;modelVersion&gt;4.0.0&lt;/modelVersion&gt;
  
    &lt;groupId&gt;com.company.web&lt;/groupId&gt;
    &lt;artifactId&gt;scss&lt;/artifactId&gt;
    &lt;version&gt;1.0-SNAPSHOT&lt;/version&gt;
    &lt;packaging&gt;jar&lt;/packaging&gt;
  
    &lt;name&gt;scss&lt;/name&gt;
    &lt;url&gt;http://maven.apache.org&lt;/url&gt;
  
    &lt;dependencies&gt;
      &lt;dependency&gt;

        &lt;artifactId&gt;servlet-api&lt;/artifactId&gt;
        &lt;version&gt;2.4&lt;/version&gt;
        &lt;scope&gt;provided&lt;/scope&gt;
      &lt;/dependency&gt;
      &lt;dependency&gt;
        &lt;groupId&gt;javax.servlet.jsp&lt;/groupId&gt;
        &lt;artifactId&gt;jsp-api&lt;/artifactId&gt;
        &lt;version&gt;2.1&lt;/version&gt;
        &lt;scope&gt;provided&lt;/scope&gt;
      &lt;/dependency&gt;
  
    &lt;/dependencies&gt;
  
    &lt;build&gt;
  
      &lt;plugins&gt;
        &lt;plugin&gt;

          &lt;version&gt;2.0.2&lt;/version&gt;
          &lt;configuration&gt;
            &lt;source&gt;1.4&lt;/source&gt;
            &lt;target&gt;1.4&lt;/target&gt;
          &lt;/configuration&gt;
        &lt;/plugin&gt;
  
  &lt;!--       To use the plugin goals in your POM or parent POM --&gt;
        &lt;plugin&gt;
          &lt;groupId&gt;org.jasig.maven&lt;/groupId&gt;

          &lt;version&gt;1.1.0&lt;/version&gt;
        &lt;/plugin&gt;
  
      &lt;/plugins&gt;

        &lt;/plugins&gt;
  
      &lt;/pluginManagement&gt;
  
    &lt;/build&gt;
  
  
  &lt;/project&gt;
  </code></pre>
  
  <p>I run the project with eclipse (right mouseclick on the project -> run as -> run Configuration -> and give as <code>Goals : sass:update-stylesheets</code></p>
  
  <p>eclipse prints the following error:</p>
  
  <pre><code>[ERROR] Failed to execute goal org.jasig.maven:sass-maven-plugin:1.1.0:update-stylesheets (default-cli) on project scss: The parameters 'resources' for goal org.jasig.maven:sass-maven-plugin:1.1.0:update-stylesheets are missing or invalid

  <p>What did I do wrong?</p>
