I know xdoclet is old crusty last century technology, but we use it and are
really frustrated with using it with maven. The plugin itself is seems
faulty, we can't get the task to run using 'mvn xdoclet:xdoclet' and the
codebase has not been touched in about two years leaving it in in an alpha
state.
Today, after years of relative quiet, we ran into a problem with the xdoclet
plugin failing with outofmemory exceptions on one of our developer's
machines. We found that using 2.0.5 but not older or newer versions worked.
I'd be happy to blame this problem on xdoclet (xjavadoc to be specific, see
below) except for this. Yes, we're using a hacked xjavadoc.jar to work with
generics.
This kind of stuff drives us nuts. Has anybody else seen this? Any ideas
what would cause it? Something in our own code that drives xdoclet wild in a
maven 2.0.{x!=5} way?
