title: A required class was missing while executing
body: <p>I am trying to create a plugin to HP OO, when i try to compile my projects i get the following error: </p>
  
  <pre><code>Caused by: org.apache.maven.plugin.PluginExecutionException: Execution generate-
  contentpack-plugin of goal com.hp.oo.sdk:oo-contentpack-maven-plugin:5.213:gener
  ate-contentpack failed: A required class was missing while executing com.hp.oo.s
  dk:oo-contentpack-maven-plugin:5.213:generate-contentpack: org/sonatype/aether/r
  epository/LocalRepositoryManager
  </code></pre>
  
  <p>I have tried, mvn clean install, mvn clean compile. Tried to delete the folder in repository:
  org\sonatype\aether\aether-api\1.13 to force it to re-download but it still not working, anyone knows why this is happening? I have no experience with maven and not to much with java, but i don't think it is anything wrong with the code. I do believe this i a maven/dependency issue.</p>
  
  <p>My maven version is 3.1.0 and java version is 1.7.0_17.</p>
  
  <p>Edit:
  According to another user this project should work and build fine. I get the same error on this project. <a href="https://dl.dropboxusercontent.com/u/31609552/oo-jruby-script.zip" rel="nofollow">Link to project.</a></p>
  
  <p>This is from one of the project POM.</p>
