Maven assembly -- how to create the project JAR with version included, but the artifact tar.gz file without?

Question

Using Maven I want to create 1) a JAR file for my current project with the current version included in the file name, myproject-version.jar, and 2) an overall artifact in tar.gzip format containing the project's JAR file and all dependency JARs in a lib directory and various driver scripts in a bin directory, but without the version number or an arbitrary ID in the name. I have this working somewhat using the assembly plugin, in that if I use the below pom.xml and assembly.xml then when I run 'mvn package' I can get a tar.gzip file with the JARs and scripts included as desired, however I don't seem to be able to get the naming/versioning correct -- either I get both the project's JAR file and the tar.gzip file with the version number or not depending on the build/finalName used. How can I specify these separately, and is it impossible to build the final artifact without an ID appended to the artifact name? For example I'd like to have my project's JAR file be named myproject-0.0.1-SNAPSHOT.jar and the overall "uber" artifact be named myproject.tar.gz (no version number or additional ID appended to the name). Is this possible?

My current pom.xml and asssembly.xml are included below.

Thanks in advance for any suggestions.

Answer 1

Just use ${project.artifactId} as the value for your finalName in your assembly configuration.

Example derived from your config (note the finalName element inside configuration):

        <plugin>
            <artifactId>maven-assembly-plugin</artifactId>
            <version>2.4.1</version>
            <configuration>
                <descriptors>
                    <descriptor>src/main/maven/assembly.xml</descriptor>
                </descriptors>
                <finalName>${project.artifactId}</finalName>
            </configuration>
            ...
        </plugin>

finalName for an assembly defaults to ${project.build.finalName} if you don't change it. The default value for ${project.build.finalName} is ${project.artifactId}-${project.version}

I think you are looking for this: http://maven.apache.org/plugins/maven-assembly-plugin/single-mojo.html#finalName just put it in the configuration of the plugin. however, i think you shouldn't remove the version if you planning to upload it to some repository.
