Maven adding -generic to the name of my jar - jar

Question

I am using Maven 2.2.1 and JDK 1.7.0_51 and I am re-packaging some jar files into a single jar.
I have a problem where the maven-assembly-plugin is adding -generic to the name of my jar that I am creating. The output is xxxxLib-4.2.11-generic.jar, i want it to be xxxxLib-4.2.11.jar
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

<finalName>${project.name}-${project.version}</finalName>

<plugin>

<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<descriptors>

</descriptors>
<finalName>${project.name}-${project.version}</finalName>

<execution>
<id>make-assembly</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin> ....
The assembly descriptor is as follows:
<assembly>
<id>generic</id>
<formats>
<format>jar</format>
</formats>
<baseDirectory>maven</baseDirectory>
<includeBaseDirectory>false</includeBaseDirectory>
<fileSets>
<fileSet>
<directory>${project.build.directory}/lib</directory>
<outputDirectory></outputDirectory>
</fileSet>
</fileSets>
</assembly>

Answer 1

I have found a solution to this problem, I have added the code below above the descriptors tag and this has now stopped the generic tag being added to the jar as I want.
<appendAssemblyId>false</appendAssemblyId>
<finalName>${project.name}-${project.version}</finalName>
