Stephane Nicoll commented on MASSEMBLY-194:
-------------------------------------------
This changes has broken my build apparently. I've tried to switch this
parameter on/off without success.
I have a project that builds an assembly and relies on assemblies A, B, C, D,
E. Each of those assemblies are made from a complex project so it brings extra
deps as well.
What I have is the following entry:
<dependencySet>
<useTransitiveFiltering>true</useTransitiveFiltering>
<outputDirectory>libs</outputDirectory>
<outputFileNameMapping>${artifactId}.${extension}</outputFileNameMapping>
<scope>runtime</scope>
<!-- Make sure to exclude everything specific here -->
<excludes>
<exclude>com.foo.bar:*</exclude>
</excludes>
</dependencySet>
Where com.foo.bar is the groupId of A,B,C,D,E. With beta-1,transitive
dependencies of A,B,C,D,E *are* packaged in the libs directory. With my local
2.2.-SNAPSHOT that I build before this fix, it doesn't.
I think this change introduced a regression. I am trying to reproduce with a
simple project since the one i'm using is fairly complex.

> Key: MASSEMBLY-194
> URL: http://jira.codehaus.org/browse/MASSEMBLY-194
> Project: Maven 2.x Assembly Plugin
> Issue Type: Bug
> Affects Versions: 2.2-beta-1
> Reporter: Brett Porter
> Assignee: John Casey
> Fix For: 2.2-beta-1
>
> Attachments: assembly-test.tar.gz
>
>
> 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.
