You must use the id tag when listing developers in your POM, otherwise NPE if using the changelog plugin
--------------------------------------------------------------------------------------------------------

         Key: MPCHANGELOG-76
         URL: http://jira.codehaus.org/browse/MPCHANGELOG-76
     Project: maven-changelog-plugin
        Type: Bug
 Environment: OSX 10.4.3, java 1.4.2._09, changelog-maven-plugin-2.0-beta-2-SNAPSHOT
    Reporter: Julian Wood


If you don't add an id tag to your developer in your pom (which is not required), and you configure a changelog report, then this piece of code will generate an NPE, because you can't add a null key to a Hashtable:

ChangeLog.java
--
 private Properties getUserList()
    {
        Properties userList = new Properties();
        
        Developer developer = null;
        for (Iterator i = getDevelopers().iterator(); i.hasNext();)
        {
            developer = (Developer) i.next();
            userList.put(developer.getId(), developer.getName());
        }
        
        return userList;
    }

Not sure if this should be fixed in the docs, or in code.

Thanks,
