Subject [jira] Commented: (MNG-2326) exclusion of transitive dependency is too dominant
Date Fri, 02 Jun 2006 04:56:43 GMT
    [ ] 

Andreas Schildbach commented on MNG-2326:

Because I don't need T in M. However, I can never be sure that D2 (or D3, ...) needs it. It's
the concept of responsibility that I don't need to know about the transitive dependencies
of my dependencies. Also, it could be the case that a dependency gets a new version, which
now depends on T, but I never learn about it because it is excluded.

In any case, the current (expected?) behaviour is not enough documented. Thus, I am re-opening
this issue. You can count it as a documentation bug or a wishlist item.

> Please consider the following structure: I've got a module M that has got the dependencies
D1 and D2. Both D1 and D2 depend on a transitive dependency T.
> I have excluded T from D1 per <exclusion> on the M POM in the dependency to D1.
> Now, one would expect that T is still pulled into M, because there is no exclusion on
the D2 path. But this is not the case, "mvn site" on M is missing T (in the dependency report),
and it is missing from the classpath, too. However "mvn eclipse:eclipse" on M does the job
right: T is listed.
