Is it possible to rename a maven jar-with-dependencies?

I think I've found a way to configure this directly in the pom without needing a separate jar-assembly.xml.

It's basically the same as Rich's answer, except the finalName is specified with the artifactId and version.

<plugin>
    <artifactId>maven-assembly-plugin</artifactId>
    <configuration>
        <descriptorRefs>
            <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
        <finalName>${project.artifactId}-${project.version}-full</finalName>
        <appendAssemblyId>false</appendAssemblyId>
        <archive>
            <manifest>
                <mainClass>com.mycompany.MyMainClass</mainClass>
            </manifest>
        </archive>
    </configuration>
    <executions>
        <execution>
            <id>make-my-jar-with-dependenciess</id>
            <phase>package</phase>
            <goals>
                <goal>single</goal>
            </goals>
        </execution>
    </executions>
</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>
  <artifactId>maven-assembly-plugin</artifactId>
  <version>2.2-beta-4</version>
  <executions>
    <execution>
      <id>jar-with-dependencies</id>
      <phase>package</phase>
      <goals>
        <goal>single</goal>
      </goals>
      <configuration>
        <descriptorRefs>
          <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
        <finalName>test</finalName>
        <appendAssemblyId>false</appendAssemblyId>
      </configuration>
    </execution>
  </executions>
</plugin>

Update: based on your comments, using the built-in descriptor won't work . I believe this is down to a bug in the recent versions of the assembly-plugin - they've removed support for classifiers, but the id is fixed if you use a built-in descriptor, so you end up with a big daft name.

As a workaround, you can copy the assembly descriptor used by the jar-with-dependencies descriptor and modify the id.

This example would result in the assembly id being appended to the finalName, so if you need to have a name of region-full.jar, you can specify the finalName as region and the assembly id as full. This will result in a file in target called region-full.jar, but note it will still be installed to the Maven repository as an attached artifact with full used as the classifier. As long as this id is different to that for your other assembly there should be no collision though.

The pom configuration would look like this.

<plugin>
  <artifactId>maven-assembly-plugin</artifactId>
  <version>2.2-beta-4</version>
  <executions>
    <execution>
      <id>jar-with-dependencies</id>
      <phase>prepare-package</phase>
      <goals>
        <goal>single</goal>
      </goals>
      <configuration>
        <descriptors>
          <descriptor>src/main/assembly/jar-assembly.xml</descriptor>
        </descriptors>
        <finalName>region</finalName>
      </configuration>
    </execution>
  </executions>
</plugin>

and the jar-assembly.xml in src/main/assembly like this:

<assembly>
  <id>full</id>
  <formats>
    <format>jar</format>
  </formats>
  <includeBaseDirectory>false</includeBaseDirectory>
  <dependencySets>
    <dependencySet>
      <unpack>true</unpack>
      <scope>runtime</scope>
    </dependencySet>
  </dependencySets>
  <fileSets>
    <fileSet>
      <directory>${project.build.outputDirectory}</directory>
    </fileSet>
  </fileSets>
</assembly>
