How do I add an Implementation-Version value to a jar manifest using Maven?

Question

I'd like to add an Implementation-Version line to a manifest in my jar file that reflects the POM version number. I can't for the life of me work out how to do this using the jar plugin.

Is this possible?

You would use the Maven Archiver:

<plugins>     <plugin>       <groupId>org.apache.maven.plugins</groupId>       <artifactId>maven-jar-plugin</artifactId>       <configuration>         <archive>           <manifest>             <addDefaultImplementationEntries>true</addDefaultImplementationEntries>           </manifest>         </archive>       </configuration>     </plugin>   </plugins> 

This will add the following to the manifest file:

Implementation-Title: ${pom.name} Implementation-Version: ${pom.version} Implementation-Vendor-Id: ${pom.groupId} Implementation-Vendor: ${pom.organization.name}
