Wcześniej wprowadziłem wtyczkę do zmiany nazw pakietów nadrzędnych. Dodaje element "Zmień nazwę opakowania nadrzędnego" do menu kontekstowego lub może być wywoływany przez ctrl-7.
Nie zaimplementowałem kodu, aby włączyć/wyłączyć element menu na podstawie aktywnej selekcji (jest pewien stan wyścigu, który powoduje, że kreator przestaje anulować). Jeśli aktywna selekcja jest pakietem z pakietem nadrzędnym, wybierze tego rodzica i uruchomi kreatora zmiany nazwy. Nadal musisz wybrać "zmień nazwy podpakietów" ręcznie.
Oto kod wtyczki:

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);
}
}
