karaf-assembly 4.0.5 - zip ard tar.gz files are not generated at the end of a successful maven build

Question

I am an inexperienced Java and Maven developer, although I have got karaf-assembly builds to work a couple of years ago using the Karaf 3.0.1 release.

When attempting to generating a karaf-assemby 4.0.5 for a customised product build, the zip and tar.gz files are not created at the end of the maven build. The ../target/assembly directory is created each time the maven build is run and the completion status is always "BUILD SUCCESS".

I suspect this this is because the POM file has an error highlighted by the Eclipse IDE at the section for the karaf-maven-plugin directly on the line, which is as follows:

Plugin execution not covered by lifecycle configuration: org.apache.karaf.tooling:karaf-maven-plugin:4.0.5:assembly (execution: default-assembly, phase: process- resources)

I can resolve this error in the IDE on the line by removing the "extensions" line, but then I get a "Project build error: Unknown packaging: karaf-assembly" error on the "packaging" line.

    <plugins>
        <plugin>
            <groupId>org.apache.karaf.tooling</groupId>
            <artifactId>karaf-maven-plugin</artifactId>
            **<!--  <extensions>true</extensions>  -->**
            <configuration>

                  <feature>management</feature>
                  <feature>jms</feature>

                </bootFeatures>
                <installedFeatures>
                </installedFeatures>
            </configuration>
        </plugin>

The POM file I am using is as follows:

Any suggestions would be gratefully received.

You might be missing the execution settings:

<executions>
  <execution>
    <phase>compile</phase>
      <goals>
        <goal>assembly</goal>
      </goals>
    </execution>
    <execution>
      <id>package</id>
      <goals>
        <goal>archive</goal>
      </goals>
    </execution>
</executions>
