在 Project Explorer (Eclipse) 中查找项目位置

2022-01-16 00:00:00 eclipse-plugin java eclipse project-explorer

我在上下文菜单中添加了一个按钮，仅当您在项目资源管理器窗口中单击鼠标右键时才会执行.我希望能够在 Project Explorer 窗口中抓取每个项目并抓取 ProjectName 和 ProjectLocation 并将其单独放入一个对象中并返回新的对象数组.

I've added a button in the context menu to execute only when you right click in the Project Explorer window. I want to be able to grab each project in the Project Explorer window and grab the ProjectName and ProjectLocation and put that into an object by itself and return the new array of objects.

我找不到访问所需信息的方法.

I can't find a way to access the information that I need.

插件.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

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.有什么帮助吗?

I feel as though tree or selTree would have the information I want but I can't find it. Any help?

推荐答案

使用来自选择提供者的选择数据:

Use the selection data from the selection provider:

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();

要让所有项目使用:

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

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