[Building Sakai] Add/updating jars on the maven repository

[Brian Baillargeon]

Last week I created a patch and Bryan Holladay updated 
https://source.sakaiproject.org/svn/msgcntr/branches/msgcntr-2.8.x/
We'd like to pull down a compiled jar with Maven rather than keeping it 
in our svn .externals file and building it locally. Is it bad practice 
to put up a jar whose version ends with '-SNAPSHOT'? Is there a process 
to add/update jars in the maven repository?

Thanks,
Brian
