  <description><![CDATA[
    Maven 4 Plugin descriptor, stored in {@code META-INF/maven/plugin.xml} in a plugin's jar artifact.
    This descriptor is generally using the information contained in the annotations of the plugin api.

// See the License for the specific language governing permissions and
// limitations under the License.

// This is a sample chained plugin that supports multiple CNI versions. It
// parses prevResult according to the cniVersion
package plugin

import (
	"context"
	"encoding/json"
	"errors"
	"fmt"
	"path/filepath"
	"runtime/debug"
	"strconv"
	"time"

  the component descriptor and when it's loaded we can add the discoverer, that would be simpler. I could
  also do this with the lister as well
i'l
// 1 the metadata -> model plugin/mojo descriptor
// 2 tools for doing the mapping
// 3 the component model -> interfaces for the plugin

// The plugin manager should load up a directory structure of plugins.
