Short version: I have a module in a multi-module maven build that
depends on other modules in the same project. I'd like to merge all 3rd
party transitive dependencies into a single .jar, but NOT include any
dependencies from the project in that .jar. I can't find a way to get
the assembly plugin to do this.
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
