getting null in manifest when using custom

[eyal edri]

Hello,

i don't know if this a bug or a misuse of the archiver.

when using a custom layout in manifest, i get 'null' for every value i use:

<build>
  <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-jar-plugin</artifactId>
        <configuration>
          <archive>
            <!-- define class path and main class -->
            <manifest>
              <addClasspath>true</addClasspath>

 <mainClass>${project.groupId}.${project.artifactId}</mainClass>
              <classpathLayoutType>custom</classpathLayoutType>

 
<customClasspathLayout>/usr/lib/ctch/java/${artifact.groupIdPath}/${artifact.artifactId}</customClasspathLayout>
            </manifest>
          </archive>
        </configuration>
      </plugin>
   </plugins>
 </build>

the manifest.mf:
