The problem lies in the wildcards I used. Wildcards don't seem to work
as advertised. Maybe assembly doesn't support simple groupId wildcards
in the form of groupId:*? Instead, I have to manually list every single
module to exclude, which means I'm repeating myself since this list
mirrors the dependencies I've already declared in the .pom. I now have
to remember to update both my .pom and my assembly .xml whenever I add a
module to the webstart deploy.

Long version: I have a multi-module maven build, which produces a .jar
for each module (this is good). Now I'd like to merge all 3rd party
dependencies into a single jar. I'm deploying my app via webstart,
and the idea is that the modules of the app will change frequently, so
they need to be downloaded separately, but 3rd party dependencies will
not change often, and it is faster to download them all in one merged
.jar via webstart. In the end, I want something like this:
my-app-module1.jar
my-app-module2.jar
3rdpartylibs.jar
My master .pom includes a modules section that looks something like this:
<modules>
<module>my-app-module1</module>
<module>my-app-module2</module>
<module>3rdpartylibs</module>
</modules>
The only dependencies declared by the 3rdpartylibs module are on the
other two modules (my-app-module1, my-app-module2). I'd like the
transitive dependency feature of maven to pick up all the other
dependencies. I use the assembly plugin with the assembly definition
below. The idea is that it will pick up all dependencies, including
transitive, and then filter out all my project's artifacts via the
<exclude>com.myGroupId:*</exclude>. Instead, it includes ALL
dependencies, including the two modules (which are in the
com.myGroupId group). It's as if the <exclude> was completely ignored.
<assembly>
<id>3rd-party-dependencies</id>
<formats>
<format>jar</format>
</formats>
<includeBaseDirectory>false</includeBaseDirectory>
<dependencySets>
<dependencySet>
<excludes>
<exclude>com.myGroupId:*</exclude>
</excludes>
<outputDirectory>/</outputDirectory>
<unpack>true</unpack>
<scope>runtime</scope>
</dependencySet>
</dependencySets>
</assembly>
I'm new to maven, so I might be missing something here. Any help is
appreciated.
Thanks,
Andy
