[jira] Updated: (MANT-52) NullPointerException when
maven-javadoc-plugin configuration defines multiple group elements within a
groups list element.
[ http://jira.codehaus.org/browse/MANT-52?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Benjamin Bentmann updated MANT-52:
----------------------------------
Description:
When attempting to run mvn ant:ant on sesame-2.2.4 available here [1]. A NullPointerException is raised. [2] for build log segment.
It seems that when a pom ( or a parents pom ) defines the following configuration the existing code the error was occuring. I have assumed in my patch that this is the only valid way of defining groups. But at least the fix is small and easy for you to figure out.
