title: Maven does not add classpath to Eclipse project
body: <p>I have a maven project, that I'm working on Eclipse. </p>
  
  <p>I use maven eclipse:eclipse to generate the classpath, but ... it NEVER adds the classpath on the eclipse project. I've tried the maven-eclipse-plugin, I've tried the M2Eclipse plugin, but it doesn't matter what I do, I can't get the classpath entries to start working. I have many build errors, even thought the maven builds the ear perfectly.</p>
  
  <p>Any guidelines? </p>
  
  <p>Thanks for any answer!</p>
  
  <p>UPDATE: Here's my root classpath:</p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;classpath&gt;
      &lt;classpathentry kind="src" path="core/src/main/java"/&gt;
      &lt;classpathentry excluding="**" kind="src" output="target/classes" path="core/src/main/resources"/&gt;
      &lt;classpathentry kind="src" path="client/src/main/java"/&gt;
      &lt;classpathentry kind="src" path="client/src/main/resources"/&gt;
      &lt;classpathentry kind="src" path="junit_server/src/main/java"/&gt;
      &lt;classpathentry kind="src" path="initializer/src/main/java"/&gt;
      &lt;classpathentry kind="src" path="initializer/src/main/webapp"/&gt;
      &lt;classpathentry kind="src" path="site/src/main/webapp"/&gt;
      &lt;classpathentry kind="src" path="core/src/test/java"/&gt;
      &lt;classpathentry kind="src" path="core/src/test/resources"/&gt;
      &lt;classpathentry exported="true" kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/&gt;
      &lt;classpathentry exported="true" kind="var" path="M2_REPO"/&gt;
      &lt;classpathentry kind="output" path="target/classes"/&gt;
  &lt;/classpath&gt;
