如何在eclipse中获取项目名称？

如何获取当前eclipse项目的名称？ 我在GMF视图中，并且在使用弹出菜单的某个子菜单时需要项目名称。

Answer 1

如果您有权访问ResourcesPlugin名称，那么这个GMF类有一个简单的答案：

IProject project = ResourcesPlugin.getWorkspace().getRoot().getProject(myBundleName); 

通用答案（来自可能过时的代码 ）可能就像（如果您打开了一个编辑器）：

 IEditorPart editorPart = getSite().getWorkbenchWindow().getActivePage().getActiveEditor(); if(editorPart != null) { IFileEditorInput input = (IFileEditorInput)editorPart.getEditorInput() ; IFile file = input.getFile(); IProject activeProject = file.getProject(); String activeProjectName = activeProject.getName(); //... use activeProjectName } 

如果没有打开编辑器：

  IViewPart [] parts = MyPlugin.getDefault().getWorkbench().getActiveWorkbenchWindow().getActivePage().getViews(); IProject activeProject = null; for(int i=0;i 

Answer 2

使用选择服务将为您提供当前选定的对象，然后您可以检查选择类型并根据选择获取项目。

如果您创建ISelectionListener并在ISelectionService上注册为侦听器，则只要活动选择发生更改，您就会收到通知，并且会为选择和拥有部分提供引用。

 ISelectionListener listener = new ISelectionListener() { public void selectionChanged(IWorkbenchPart sourcePart, ISelection selection) { setSourcePart(sourcePart); setSelection(selection); } }; ... //register the listener selectionService.addSelectionListener(listener); ... //either get the selection service and get the selection, or use the stored version from the listener ISelectionService selectionService = Workbench.getInstance().getActiveWorkbenchWindow().getSelectionService(); ISelection selection = selectionService.getSelection(); if(selection instanceof IStructuredSelection) { Object element = ((IStructuredSelection)selection).getFirstElement(); IProject project; if (element instanceof IResource) { project= ((IResource)element).getProject(); } else if (element instanceof PackageFragmentRootContainer) { IJavaProject jProject = ((PackageFragmentRootContainer)element).getJavaProject(); project = jProject.getProject(); } else if (element instanceof IJavaElement) { IJavaProject jProject= ((IJavaElement)element).getJavaProject(); project = jProject.getProject(); } } else if (selection instanceof ITextSelection) { if(sourcePart instanceof JavaEditor) { IJavaElement element = SelectionConverter.resolveEnclosingElement(sourcePart, selection); project = element.getJavaProject().getProject(); } } 

有关更多详细信息，请参阅Eclipse选择服务上的这篇文章 。

我从上面的post中创建了一个很好的function，并添加了一些更新。 适用于当前的日食。

 public static IProject getCurrentSelectedProject() { IProject project = null; ISelectionService selectionService = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getSelectionService(); ISelection selection = selectionService.getSelection(); if(selection instanceof IStructuredSelection) { Object element = ((IStructuredSelection)selection).getFirstElement(); if (element instanceof IResource) { project= ((IResource)element).getProject(); } else if (element instanceof PackageFragmentRoot) { IJavaProject jProject = ((PackageFragmentRoot)element).getJavaProject(); project = jProject.getProject(); } else if (element instanceof IJavaElement) { IJavaProject jProject= ((IJavaElement)element).getJavaProject(); project = jProject.getProject(); } } return project; }

Rich Seller和VonC都提供了很好的答案，但它们似乎不够完整/使用内部类。 我想出了以下内容。

 @Override public void createPartControl(Composite parent) { .... // Register to be notified about selections getSite().getWorkbenchWindow().getSelectionService() .addPostSelectionListener(this); // Detect the current selection detectCurrentSelection(); } @Override public void selectionChanged(IWorkbenchPart part, ISelection selection) { IProject project = convertSelection(part, selection); setProject(project); } private void detectCurrentSelection() { IProject project = null; IWorkbenchWindow window = getSite().getWorkbenchWindow(); IWorkbenchPage activePage = window.getActivePage(); if (activePage != null) { IEditorPart part = activePage.getActiveEditor(); if (part != null) { project = convertSelection(part); } else { IViewReference[] viewReferences = activePage.getViewReferences(); for (IViewReference viewRef : viewReferences) { IViewPart view = viewRef.getView(false); ISelection selection = null; if (view instanceof IPackagesViewPart) { IPackagesViewPart viewPart = (IPackagesViewPart) view; TreeViewer treeViewer = viewPart.getTreeViewer(); selection = treeViewer.getSelection(); } else if (view instanceof CommonNavigator) { CommonNavigator navigator = (CommonNavigator) view; CommonViewer commonViewer = navigator.getCommonViewer(); selection = commonViewer.getSelection(); } if (selection instanceof IStructuredSelection) { IStructuredSelection structuredSelection = (IStructuredSelection) selection; project = convertSelection(structuredSelection); if (project != null) break; } } } } setProject(project); } private IProject convertSelection(IWorkbenchPart part, ISelection selection) { IProject project = null; if (selection instanceof IStructuredSelection) { IStructuredSelection structuredSelection = (IStructuredSelection) selection; project = convertSelection(structuredSelection); } else if (selection instanceof ITextSelection) { if (part instanceof IEditorPart) { IEditorPart editorPart = (IEditorPart) part; IResource resource = (IResource)editorPart.getEditorInput().getAdapter(IResource.class); if (resource != null) { project = resource.getProject(); } } } return project; } private IProject convertSelection(IEditorPart part) { IProject project = null; IResource resource = (IResource)part.getEditorInput().getAdapter(IResource.class); if (resource != null) { project = resource.getProject(); } return project; } private IProject convertSelection(IStructuredSelection structuredSelection) { IProject project = null; Object element = structuredSelection.getFirstElement(); if (element instanceof IResource) { project = ((IResource) element).getProject(); } else if (element instanceof IJavaElement) { IJavaElement javaElement = (IJavaElement) element; project = javaElement.getJavaProject().getProject(); } else if (element instanceof IAdaptable) { IAdaptable adaptable = (IAdaptable) element; IWorkbenchAdapter adapter = (IWorkbenchAdapter) adaptable.getAdapter(IWorkbenchAdapter.class); if (adapter != null) { Object parent = adapter.getParent(adaptable); if (parent instanceof IJavaProject) { IJavaProject javaProject = (IJavaProject) parent; project = javaProject.getProject(); } } } return project; }
