Subject [jira] Commented: (IVY-725) Null Pointer Exception during retrieve/resolve
Date Thu, 14 Feb 2008 09:05:08 GMT

    [ https://issues.apache.org/jira/browse/IVY-725?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12568836#action_12568836
] 

Xavier Hanin commented on IVY-725:
----------------------------------

What do you mean by auto generated? Do you use the makepom task? If so, could you please provide
your original ivy file, and the generated pom? If you don't use makepom, Ivy does not generate
poms, it actually converts poms to ivy files to work.
