He intentado implementar un complemento para cambiar el nombre de los paquetes principales. Agrega un elemento "Cambiar el nombre del paquete principal" al menú contextual de, o puede ser activado por ctrl-7.
No he implementado el código para habilitar/deshabilitar la opción del menú en función de la selección activa (hay alguna condición de carrera que hace que el asistente deje de cancelar). Si la selección activa es un paquete con un paquete principal, seleccionará ese elemento principal e iniciará el asistente de cambio de nombre. Aún deberá seleccionar "cambiar nombre de subpaquetes" manualmente.
Aquí está el código del plugin:
package name.seller.rich.packagerenamer.actions;
import org.eclipse.core.commands.AbstractHandler;
import org.eclipse.core.commands.ExecutionEvent;
import org.eclipse.core.commands.ExecutionException;
import org.eclipse.jdt.core.IJavaElement;
import org.eclipse.jdt.core.IPackageFragment;

import org.eclipse.jdt.core.JavaModelException;
import org.eclipse.jdt.internal.ui.JavaPlugin;
import org.eclipse.jdt.internal.ui.actions.SelectionConverter;
import org.eclipse.jdt.ui.actions.RenameAction;
import org.eclipse.jface.viewers.IStructuredSelection;
import org.eclipse.jface.viewers.StructuredSelection;
import org.eclipse.ui.IWorkbenchPart;
import org.eclipse.ui.handlers.HandlerUtil;
public class RenameParentPackageHandler extends AbstractHandler {
public RenameParentPackageHandler() {
}
public Object execute(ExecutionEvent event) throws ExecutionException {
IWorkbenchPart activePart = HandlerUtil.getActivePart(event);
try {
IStructuredSelection selection = SelectionConverter
.getStructuredSelection(activePart);
IPackageFragment parentPackage = getParentPackage(selection);
if (parentPackage != null && parentPackage.exists()) {
RenameAction action = new RenameAction(HandlerUtil
.getActiveSite(event));
StructuredSelection parentSelection = new StructuredSelection(
parentPackage);
action.run(parentSelection);
}
} catch (JavaModelException e) {
logException(e);
}
return null;
}
private IPackageFragment getParentPackage(IStructuredSelection selection) {
IJavaElement[] elements = SelectionConverter.getElements(selection);
if (elements != null && elements.length > 0) {
if (elements[0] != null && elements[0] instanceof IPackageFragment) {
IPackageFragment fragment = (IPackageFragment) elements[0];
String packageName = fragment.getElementName();
int lastDotIndex = packageName.lastIndexOf(".");
if (lastDotIndex != -1) {
String parentPackageName = packageName.substring(0,
lastDotIndex);
IJavaElement parent = fragment.getParent();
if (parent != null
&& parent instanceof IPackageFragmentRoot) {
return ((IPackageFragmentRoot) parent)
.getPackageFragment(parentPackageName);
}
}
}
}
return null;
}
protected void logException(Exception e) {
JavaPlugin.log(e);
}
}
