Subject RE: suggestion refactor SCM
Date Tue, 27 Sep 2005 09:50:51 GMT
I think that it will be a very good idea, mostly as a stepping stone to
higher level functionality.

The main reason for not having such a thing is the fact that each
project knows in advance what kind of repository is being in used. So
why do we need something abstract?

On the other hand, once you have such an abstracted functionality, I am
sure we could envision higher level tasks stored on other antlibs that
may provide project management style functionality irrespective of the
underlying repository. That would be a very good thing to have.

So I am all for it. The question is what are the concepts that can be
ported across all different SCMs?

As per syntax, I would much prefer something like:

 <scm:commit ...../>

Now, can this be done in such a way as to figure out by itself what is
the underlying repository is. That would limit the need for magic stuff.
