Creating a Plugin Class

public class MyPlugin extends Plugin {
public static final String EXTENSION_POINT_ID = "";
@Override
public void start(BundleContext context) throws Exception {
(context);
ExtensionRegistry registry = ();
IExtensionPoint extensionPoint = (EXTENSION_POINT_ID);
IExtension[] extensions = ();
for (IExtension extension : extensions) {
// Do something with the extension
}
}
}
```

Packaging the Plugin

1. Right-click on the plugin project and select "Export".
2. In the "Export" dialog box, select "Deployable plug-ins and fragments" and click "Next".
3. Select the plugin project and click "Finish".

Installing the Plugin

1. Copy the generated JAR file to the Eclipse plugins directory.
2. Restart Eclipse.
