Convert Ant PluginTask to Maven plugin

[Copilot]

Converts the Ant-based PluginTask from builder/src/builder/org/jnode/build/PluginTask.java to a Maven plugin. This enables plugin building in Maven-based workflows without Ant dependency.

Implementation

Created jnode-maven-plugin/ module containing:

• PluginBuildMojo - Maven equivalent of PluginTask

  • Parses plugin descriptor XMLs via NanoXML
  • Generates plugin JARs with OSGi manifests (Bundle-SymbolicName, Bundle-Version)
  • Parallel building via ThreadPoolExecutor
  • Incremental builds (timestamp-based)

• Dependencies - Uses build-time plugin classes from mavenizer/src/main/endorsed

  • Avoids runtime VM dependencies (org.jnode.vm.*)
  • Includes Factory, PluginDescriptor, Library, Runtime model classes

Configuration

<plugin>
    <groupId>org.jnode</groupId>
    <artifactId>jnode-maven-plugin</artifactId>
    <version>1.0-SNAPSHOT</version>
    <configuration>
        <descriptorsDirectory>${basedir}/descriptors</descriptorsDirectory>
        <outputDirectory>${project.build.directory}/plugins</outputDirectory>
        <pluginDirectory>${project.build.directory}/classes</pluginDirectory>
        <libraryAliases>
            <jnode-core.jar>${jnode-core.jar}</jnode-core.jar>
        </libraryAliases>
    </configuration>
</plugin>

Limitations

• Library export/exclude filtering partially implemented (placeholder in addLibraryToJar())
• Packager subtasks not converted (can be added if needed)

Original prompt

First, read documentation in docs/plugins directory of JNode project to understand how JNode plugins work.
jnode-_{.jar are not a real jar at runtime, they are only there to represent at build time all classes of the sub projects of jnode (fs, core, gui ...).
Example : jnode-fs.jar represents all classes of the fs sub project of jnode.}

Then convert the nat task in builder/src/builder/org/jnode/build/PluginTask.java to maven
