How to get rid of maven-antrun-plugin here? - maven

Question

The problem is as follows: I need to generate files in META-INF so that registering using ServiceLoader works. FWIW, this is maven 3.0.4. The full link to the pom.xml file is here.
In order to generate these files, I use this plugin as follows:
<properties>
<serviceName>com.github.fge.msgsimple.serviceloader.MessageBundleProvider</serviceName>
</properties>
<!-- .... -->
<plugin>
<groupId>eu.somatik.serviceloader-maven-plugin</groupId>
<artifactId>serviceloader-maven-plugin</artifactId>
<version>1.0.2</version>
<configuration>
<services>
<param>${serviceName}</param>
</services>
</configuration>
<executions>
<execution>
<phase>compile</phase>
<goals>
<goal>generate</goal>
</goals>
</execution>
</executions>
</plugin>
However, the generated file (META-INF/services/xxxx) don't find their way into the generated jar, so I have to resort to this (your eyes may bleed):
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.7</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>run</goal>
</goals>
<configuration>
<target>
<property name="jarname"
value="${project.name}-${project.version}.jar"/>
<property name="victim"
value="${project.build.directory}/${jarname}"/>
<property name="serviceFile"
value="${project.build.directory}/classes/META-INF/services/${serviceName}"/>
<echo>${victim}</echo>
<echo>${serviceFile}</echo>
<jar destfile="${victim}" update="true">
<zipfileset file="${serviceFile}"
prefix="META-INF/services/"/>
</jar>
</target>
</configuration>
</execution>
</executions>
</plugin>
I am aware of the shade plugin. I have tried it, battled with it for hours on end, with no success at all. It just wouldn't include the file. The above is the only solution that works for me.
But this solution is not sustainable. I also want to generate jar with dependencies, and in this case the service file needs to be appended to; and the solution above only works for jars without dependencies...
So, what plugin would you need to make the whole thing work seamlessly? How do you configure it?

Have you considered the assembly plugin? I find it quite powerful.
