Can not set the final jar name with maven-assembly-plugin

You can specify the finalName property to give the jar the name you want, and specify that appendAssemblyId should be false to avoid the jar-with-dependencies suffix.
The configuration below will output a jar called test.jar

         <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-assembly-plugin</artifactId>
            <version>2.4</version>
            <configuration>
                <finalName>test</finalName>
                <archive>
                    <manifest>
                        <mainClass>com.myapp.Main</mainClass>
                    </manifest>
                </archive>
                <descriptorRefs>
                    <descriptorRef>jar-with-dependencies</descriptorRef>
                </descriptorRefs>
               <appendAssemblyId>false</appendAssemblyId>
            </configuration>
         </plugin>
