[jira] Updated: (MSHARED-77) DependencyTreeResolutionListener throws NullPointerException

["Christian Schulte (JIRA)" <ji...@codehaus.org>]

     [ http://jira.codehaus.org/browse/MSHARED-77?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Christian Schulte updated MSHARED-77:
-------------------------------------

    Attachment: MSHARED-77.patch

Patch to use artifact.getDependencyConflictId() instead of artifact.getId() as the key to the map of premanaged scopes. This solves the NullPointerException for me and should not change anything for projects not using version ranges in the dependency management.
