Subject Any plans to fix/update maven-scm-provider-hg ?
Date Thu, 13 Jan 2011 22:58:07 GMT
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 

First, you have it being out of date.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}]
[INFO] Retrieving previous build number from
[INFO] Removing C:\DOCUME~1\Owner\LOCALS~1\Temp\wagon-scm1210107000.checkout\pir

[INFO] ------------------------------------------------------------------------
[INFO] ------------------------------------------------------------------------
[INFO] Error deploying artifact: Error listing repository: No such command 
(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 ( ). 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?
