In Maven, How can I get 2 copies of the jar with dependencies, but with different names? - maven

Question

I'm working on a Maven project and the assembly that I have setup creates a jar with all the dependencies that I need, as of now the configuration builds 2 different jars "project-jar-with-dependencies.jar" and "project-plugin.jar", but I would like to build a copy of the "project-plugin.jar" that does not contain the "-plugin" at the end.
I'm aware of the usage of the tag "appendAssemblyId", however when I try to use it I always end up with a jar that contains much more that what's needed even if that is the only change in the configuration tag. I also tried using the "finalname" tag, but this one does not seem to change anything.
This is the pom.xml that I'm using:

And this is the Assembly.xml:

</file>
<!--This is an attempt at generating a jar without the '-plugin' in the target directory -->
<file>
<source>target/build/${project.build.finalName}.jar</source>
<outputDirectory>${basedir}/target/</outputDirectory>
</file>
<file>
<source>plugin.xml</source>
<outputDirectory>/</outputDirectory>
<filtered>true</filtered>
</file>
</files>
</assembly>
As mentioned, I tried to use the AppendAssemblyId false, but whenever I use it it also changes the contents of the jar, I could also be that I'm putting it in the wrong place.
Is there a way to create a jar that's and exact copy of the mentioned jar, but without the "-plugin" at the end? Or is there a way to take that string out of the jar that's already being created?
Thanks
