Oleg,
Shane and I were chatting and I think the maven-mercury module in
trunk can actually go into Mercury itself, there is nothing trunk
specific in there and almost makes you trunk free.
This kind of beats the purpose of externalizing dependency processing.
Mercury defines an interface that any dependency reader should
implement, maven-mercury is the maven POM specific implementation.
Why would we stick specific implementation with a generic interface? It
would make sense if we also externalize POM processing from the trunk
and make it into a component (see below). In this case implementation
will be an adapter, that will not depend on the trunk.
We're trying to figure out what to do with the project builder which
only relies on maven-shared-model. Once alpha-1 is release I don't
want the external dependency structure changing, or the layout of the
modules changing in trunk so if you can move that back to Mercury that
would be cool.
That's a hard one. Original idea of Mercury was to make it a
Maven-independent library. Well - because Mercury provides access to M2
repositories - it has to read POMs, so some kind of Maven dependency is
a must. I think that POM processing should be externalized into
independent component, so that shared-model + pom-interpreter are a low
level libraries that Mercury and project builder can depend on. Is that
even possible?
Shane, it is possible to make POM reader into a component? How clear are
it's interfaces?
Might you also take a look and verify that Mercury builds with trunk
and close the issue for 3.0-alpha-1 if it works.
Trying, trunk did not compile for me yesterday. I will update jira as
soon as everything works together.
Thanks,
Oleg
Thanks,
