title: Hudson build fail: Non-resolvable parent POM
body: <p>I used to work with Hudson on my project, and lately I had to move it to a new server.</p>
  
  <p>I configured it the exact same way it use to be (for all I can tell) but when I try to launch a build, it fails and I get the following error:</p>

  <p>The pom.xml file when I got to Hudson "workspace" looks like this:</p>
  
  <p>
  [...]</p>
  
  <pre><code>    &lt;parent&gt;
          &lt;groupId&gt;com.rha&lt;/groupId&gt;
          &lt;artifactId&gt;MyProject&lt;/artifactId&gt;
          &lt;version&gt;1.0-SNAPSHOT&lt;/version&gt;
      &lt;/parent&gt;
  </code></pre>
  
  <p>[...]</p>
  
  <pre><code>    &lt;dependencies&gt;
          &lt;dependency&gt;
              &lt;groupId&gt;com.rha&lt;/groupId&gt;
              &lt;artifactId&gt;business&lt;/artifactId&gt;
              &lt;version&gt;1.0-SNAPSHOT&lt;/version&gt;
              &lt;type&gt;ejb&lt;/type&gt;
          &lt;/dependency&gt;
          &lt;dependency&gt;
              &lt;groupId&gt;com.rha&lt;/groupId&gt;
              &lt;artifactId&gt;web&lt;/artifactId&gt;
              &lt;version&gt;1.0-SNAPSHOT&lt;/version&gt;
              &lt;type&gt;war&lt;/type&gt;
          &lt;/dependency&gt;
      &lt;/dependencies&gt;
  
  &lt;/project&gt;
  </code></pre>
  
  <p><strong>[Edit]</strong></p>
  
  <p>Actually I forgot some important informations:</p>
  
  <p>My project is divided into 3 parts:</p>
  
  <p>business (packaged into .jar)
  web (packaged into a .war)
  ear (packaged the .war and .jar into a .ear)</p>
  
  <p>I'm using Subversion, and under my "trunk" folder I got a "MyProject" folder including:</p>
  
  <pre><code>.project
  .settings/
  business/
  ear/
  pom.xml
  src/
  web/
  </code></pre>
  
  <p>what happens is:</p>
  
  <p>in my Hudson job configuration, I filled the SVN field "repository URL" with:</p>
  
  <blockquote>
    <p>http://[...]/trunk/MyProject/ear</p>
  </blockquote>
  
  <p>and here is the "pom.xml" from "MyProject" folder:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 
  
  [...]
      &lt;modules&gt;
          &lt;module&gt;business&lt;/module&gt;
          &lt;module&gt;web&lt;/module&gt;
          &lt;module&gt;ear&lt;/module&gt;
      &lt;/modules&gt;
  [...]
  </code></pre>
  
  <p>so the parent "pom.xml" is actually located at "../pom.xml" on my SVN repository, under "trunk/MyFolder".</p>
  
  <p>But Hudson can't see it for some reason (but like I said, it used to work on the previous server).</p>
  
  <p>Any clue ?</p>
  
  <p><strong>[/Edit]</strong></p>
  
  <p>I guess this is a rookie mistake, I'm a total beginner on Maven, but I just can't figure out why it's not working anymore ... </p>
  
  <p>Any help will be greatly appreciated !</p>
