externalize deploy goal commands?

[Joe Germuska <Jo...@Germuska.com>]

Has there been any discussion about externalizing the commands used 
by the various Maven deploy goals?  For example, the distribution 
goals for site:deploy and dist:deploy use the "U" flag to tar, which 
apparently my server doesn't understand.  Now, I can ask my sysadmin 
to put in a new tar, but it seems like I should be able to change 
that.

Note that I have changed it in the plugin.jelly files, but then when 
I updated to the 1.0b9 release, my changes were blown away, so I was 
reminded that it seems like a good idea.

By the way, I've looked on other systems and on the web and I can't 
figure out -- what does "U" mean to some versions of "tar"?

Thanks
	Joe

Don't know, but it sounds like a good idea to me.

You could check the source code out using CVS, then make your local
modifications to the source tree and build your own installation of
maven. When changes are made in CVS, CVS will deal with merging those
changes into your modified version of the code.

According to GNU tar,

  -U, --unlink-first    remove each file prior to extracting over it

I don't immediately see the importance of using this option when
extracting tar files - the GNU tar documentation seems to make it sound
like a performance thing. I suppose it might make a difference if the
permissions on the existing files don't allow you to write to them, but
you can unlink them and create new ones. But I'd have thought that would
be a special case rather than the default.

-Mark.
