I am running java version “21.0.4” 2024-07-16 LTS

I downloaded the https://github.com/eclipse-ee4j/glassfish-samples. and trying to buld the jakarta9 files.

I get Caused by: org.apache.maven.plugin.PluginExecutionException: Execution default-war of goal org.apache.maven.plugins:maven-war-plugin:3.0.0:war failed: Unable to load the mojo ‘war’ in the plugin ‘org.apache.maven.plugins:maven-war-plugin:3.0.0’ due to an API incompatibility: org.codehaus.plexus.component.repository.exception.ComponentLookupException: null

my pom file is:

        </plugin>
    </plugins>
</build>

Any suggestion??

I tried the maven-compiler-plugin, maven-war-plugin to be as most compatible wth java 21.
