John Casey closed MASSEMBLY-194.
--------------------------------
Assignee: John Casey
Resolution: Fixed
Fix Version/s: 2.2-beta-1
I've added a <useTransitiveFiltering/> flag to the <dependencySet/> that is set
to false by default. This restores backward compatibility with 2.1 on this
point, where the transitive path of an artifact will not be considered when
looking at includes/excludes patterns. If this flag is set to true, it allows
you to filter the entire subgraph based on one pattern...so that when you
exclude one dependency, you also exclude all of its dependencies (which is more
correct).
In fact, this "feature" is a bug in the 2.1 code. The more correct way to fix
this, given your example, would be to create a build extension that supplies an
artifact handler for tar.gz artifacts. Doing this, you could specify
<includesDependencies>true</>, which is really what you're trying to accomplish
here.
In any case, I've included a new unit test to check this flag (both directions
using that and an existing test), and re-deployed the patched code as a new RC
for 2.2-beta-1.

> See the attached test project. It requires that you've run mvn clean install
> for continuum previously so there is a sizable dependency in the repo to play
> with.
> If you build with assembly 2.1, only the tarball is expanded and included in
> the final distribution (about 27mb)
> With 2.2-beta-1, all the transitive dependencies are also expanded and
> included (about 65mb).
> This is a functionality change, but also consumes a very large amount of
> memory and CPU.
