-----------------------------------

Thanks, Kenney.  Feel free to delete that comment and I'll post elsewhere (I don't have delete rights).

That stacktrace occurred when building the:
XDoclet head
xdoclet-maven-plugin head using XDoclet that was built (xdoclet-1.3-SNAPSHOT.jar - both jar files & modules) - I changed the xdoclet versions in pom.xml of the xdoclet-maven-plugin to -1.3-SNAPSHOT.

When building the xdoclet-maven-plugin from the source, using xdoclet-1.2.3.jar, and running mvn install on my project I get:

This error is what had initially led me to this post, based on the comments here:

http://jira.codehaus.org/browse/MOJO-223

Thanks again for your help.

>      Project: XDoclet
>         Type: Bug

> This is somewhat related to XDT-879.
> In version 1.2.3, ModuleFinder.resetFoundModules is reset,
> but the DocletTask.subtaskMap and subtaskNameMap are not.
> This results in re-scanning for modules for each DocletTask,
> which is good.  However, when you use ejbdoclet and webdoclet
> together, you get an AMBIGUOUS_SUBTASK_DEFINITION error
> for 'service-endpoint', which is in both the ejb and the web
> module (ServiceEndpointSubTask).
> This is because when one task is finished (say ejbdoclet) and
> the next one is initializing (say webdoclet), the static subtaskMap is still there containing the subtasks of ejbdoclet (which contains 'service-endpoint'.
> DocletTask.registerModules then sees the duplicate taskname and different packages for the classes, and bails.
> Btw, a fix is to set subtaskMap and subtaskNameMap to null - works fine!
> The strange thing is that this doesn't normally occur in Ant,
> but i discovered this when running a custom app embedding ant

> By the slight chance that this is not a bug, can someone tell me
