maven assembly ignores finalName for dependent artifacts - maven-2

Question

I have a hierarchical maven project, from which I am trying to build a native installer for several of the sub-modules. I am using my product name as a prefix: <finalName>xyz-${artifactId}</finalName> in the parent POM so that all my artifact jars have a standard naming convention.
xyz-parent
+-- util
+--- target/xyz-util.jar
+-- core
+--- target/xyz-core.jar
+-- app1 <--- "builds an installer as part of the package phase"
+--- target/xyz-app1.jar
+-- app2 <--- "builds an installer as part of the package phase"
...
I need to materialize all the dependent jars into a directory (since inno setup knows nothing about maven). So for each submodule which is an installer I plan to use maven-assembly-plugin, then use something like the following in my inno setup:
Source: "target\pkg\lib\*.jar"; DestDir: "{app}\external"; Flags: ignoreversion;
When I run mvn clean package, I get a target/xyz-app1-bin/xyz-app1/lib directory with all of the dependent jars, however none of the jars produced by my sibling projects have their correct final names (e.g. I have util-0.0.1-SNAPSHOT.jar instead of xyz-util.jar)
This problem seems similar to this post, but I have no idea what "attach" is (perhaps deprecated).

Answer 1

I was unable to use finalName directly, however, I did manage to re-implement the finalName logic I wanted using dependency sets -- thus partitioning my dependencies into an external and internal set (based on the groupId):
<assembly>
<id>bin</id>
<formats>
<format>dir</format>
</formats>
<dependencySets>
<dependencySet>
<outputDirectory>external</outputDirectory>
<outputFileNameMapping>
${artifact.artifactId}.${artifact.extension}
</outputFileNameMapping>
<excludes>
<exclude>com.xyz:*</exclude>
</excludes>
</dependencySet>
<dependencySet>
<outputDirectory>lib</outputDirectory>
<outputFileNameMapping>
xyz-${artifact.artifactId}.${artifact.extension}
</outputFileNameMapping>
<includes>
<include>com.xyz:*</include>
</includes>
</dependencySet>
</dependencySets>
</assembly>

You should be able to use finalName directly using (this worked for me) :
<outputFileNameMapping>
${artifact.build.finalName}.${artifact.extension}
</outputFileNameMapping>
