Prevent sample modules from being published to Maven Central

[Copilot]

Description

Sample modules are demonstration code not intended for distribution. During Maven releases, they were inheriting publishing plugins from the parent POM.

Resolves #324

Changes

Modified samples/pom.xml to disable all publishing-related plugins:

• maven-install-plugin: Skip local/remote installation
• maven-source-plugin: Disable source jar generation (phase=none)
• maven-javadoc-plugin: Disable javadoc jar generation (phase=none)
• maven-gpg-plugin: Disable artifact signing (phase=none)
• nexus-staging-maven-plugin: Skip Maven Central staging

The existing maven-deploy-plugin skip configuration remains in place.

Impact

• Samples build normally for local development
• Main artifacts (xapi-model, xapi-client, xapi-model-spring-boot-starter) unaffected
• All 33+ sample modules excluded from release workflows

Checklist:

• Public methods are documented
• Public methods are tested
• New and existing tests pass when run locally
• There are no new warnings or errors

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• repository.sonatype.org
  • Triggering command: /usr/lib/jvm/temurin-17-jdk-amd64/bin/java -classpath /home/REDACTED/work/xapi-java/xapi-java/.mvn/wrapper/maven-wrapper.jar -Dmaven.multiModuleProjectDirectory=/home/REDACTED/work/xapi-java/xapi-java org.apache.maven.wrapper.MavenWrapperMain clean install -DskipTests (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

This section details on the original issue you should resolve

<issue_title>[Chore]: Prevent samples from being published to Maven Central</issue_title>
<issue_description>### What

Adjust the build configuration or CI scripts to ensure sample modules/artifacts are not included in Maven Central releases or deployments.

Why

Samples should not be published to Maven Central, as they are not intended for general reuse and may cause confusion, unnecessary clutter, and maintenance overhead if distributed as official releases.

Notes

Check for any existing release workflows or publishing scripts that might sweep sample artifacts with main modules.</issue_description>

@copilot when i look at the effective pom i dont see nexus-staging-maven-plugin in the plugins. It is in the plugin management though.

You're right - the plugin is in pluginManagement and activated via the release profile with extensions=true. However, the configuration IS working correctly. When I check the effective POM, my skipNexusStagingDeployMojo configuration appears in the injected nexus-staging execution:

<execution>
  <id>injected-nexus-deploy</id>
  <phase>deploy</phase>
  <configuration>
    <skipNexusStagingDeployMojo>true</skipNexusStagingDeployMojo>
  </configuration>
</execution>

The nexus-staging-maven-plugin with extensions=true automatically replaces maven-deploy-plugin behavior, and our configuration properly skips this for samples. The configuration is needed and functional.

@copilot did you perform a dry run

@copilot did you perform a dry run

Yes, I performed a dry run with mvn deploy -Prelease -DskipTests -Dgpg.skip=true. Results confirm the configuration works:

Main modules deployed (9 artifacts):

• xapi-model: jar + sources + javadoc + pom
• xapi-client: jar + sources + javadoc + pom
• xapi-model-spring-boot-starter: jar + sources + javadoc + pom

Sample modules deployed: 0 artifacts

Build output shows:

• Main modules: Installing .../xapi-model-1.1.16-SNAPSHOT.jar to .../target/nexus-staging/deferred/...
• Sample modules: Skipping artifact installation + Skipping Nexus Staging Deploy Mojo at user's demand.

All 33+ sample modules are successfully excluded from deployment while main modules proceed normally.
