在 Project Explorer (Eclipse) 中查找项目位置

Find Project locations in Project Explorer (Eclipse)

我在上下文菜单中添加了一个按钮,仅当您在 Project Explorer 中右键单击时才执行 window。我希望能够在 Project Explorer window 中抓取每个项目并抓取 ProjectName 和 ProjectLocation 并将其单独放入一个对象和 return 新的对象数组中。

我找不到访问所需信息的方法。

plugin.xml

<extension point="org.eclipse.ui.menus">
    <menuContribution locationURI="popup:org.eclipse.ui.navigator.ProjectExplorer#PopupMenu">
      <command commandId="helloworld.sample"
        label="Hello World" style="push">
      </command>
    </menuContribution>
  </extension>
  <extension point="org.eclipse.ui.commands">
    <command defaultHandler="helloworld.handler.samplehandler"
      id="helloworld.sample" name="Sample">
    </command>
  </extension>

samplehandler.java

IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage();

IWorkbenchPart viewpart  = page.findView("org.eclipse.ui.navigator.ProjectExplorer");

Tree tree = (Tree) ((TreeViewer) viewpart.getSite().getSelectionProvider()).getControl(); 
TreeItem[] selTree = tree.getSelection();

我觉得好像tree 或selTree 会有我想要的信息,但我找不到。有帮助吗?

使用选择提供者的选择数据:

IStructuredSelection sel =   
     (IStructuredSelection)viewpart.getSite().getSelectionProvider().getSelection(); 

Object selObj = sel.getFirstElement();

IProject project =
   (IProject)Platform.getAdapterManager().getAdapter(selObj, IProject.class);

... might return null if selection is not the project

String name = project.getName();

IPath location = project.getLocation();

要获取所有项目,请使用:

IWorkspace workspace = ResourcesPlugin.getPlugin().getWorkspace();

IProject [] projects = workspace.getRoot().getProjects();
