Benjamin Bentmann commented on MPLUGIN-114:
-------------------------------------------
In version 2.4 and 2.4.1 of the maven-plugin-tools-api the line
PluginXdocGenerator.java:95 is
{code:java}
for ( Iterator it = pluginDescriptor.getMojos().iterator(); it.hasNext(); )
{code}
so either the plugin descriptor or its mojo collection seems to be null.
Is there a possibility to get your POM and a full debug output from Maven? Are
you working on an open-source project that I could checkout by myself to
reproduce this?
