It seems that the only way to use Mercurial in Maven is through
maven-scm-provider-hg. However there are so many problems that the plugin is
unusable
First, you have it being out of date. In Maven 2.2.1 it works somewhat (by
working I mean it detects that it exists and tries to use it), but in Maven
3.0.2 you get this:
Transfer error: org.apache.maven.scm.manager.NoSuchScmProviderException: No
such provider: 'hg'.
Second, you have the list command bug, which seems to affect even people using
hudsun. They were able to fix it by creating their own plugin, which doesn't
work with Maven-only installations. Following is the error message
[INFO] [deploy:deploy {execution: default-deploy}]

(This is replicated on site:deploy as well).
Third, you have the complete lack of documentation on using it. It took me 3+
hours to get the results above; everything else kept erroring out as I slipped
further into dependency hell. None of the projects have docs on how to use this.
Fourth, you have the abandonment of the user support mailing list (
http://mail-archives.apache.org/mod_mbox/maven-scm-users/ ). This is more
general to maven-scm, but does affect this plugin. The last email talks about
this very same problem, however it's been almost 2 months with no response.
Even
for the past year none of the support questions have been answered.
---
Combined, this leads to a plugin that isn't usable at all and can mislead
people
into thinking that it works. Are their any plans to update it? Are their any
plans to depreciate it?
Thanks,
