java - 如何从工作集中获取项目(IProject)？

Question

在下一个代码中，我将从默认工作区的项目中获取所需的信息，但我需要针对工作集的项目更改它。

    IWorkspace workspace = ResourcesPlugin.getWorkspace();

     // Get the root of the workspace
    IWorkspaceRoot root = workspace.getRoot(); 

    // Get all projects in the workspace
    IProject[] projects = root.getProjects(); 

    // Loop over all projects
    for (IProject project : projects) {
        try {
            if (project.getName().equals("RemoteSystemsTempFiles"))
            {
                System.out.println("Ignored project");
                //setSystemName(project.getName());
            }
            else
            {
                // Load the data model by extracting APIs declaration (Imports)
                printProjectInfo(project);
            }
        } catch (CoreException e) {
            e.printStackTrace();
        }
    }

所以，我找到了一个answer但当循环后返回时，我收到许多信息，例如:

- ProjectName (not open) 

或

- ProjectName
   src
      <default> (...)
        src (...)
    src.tryone (...)
   C:\Program Files\Java\jre1.8.0_31\lib\resources.jar (not open)

返回该信息的代码是:

     IWorkingSetManager manager = PlatformUI.getWorkbench().getWorkingSetManager();

    IWorkingSet [] allWorkingSets = manager.getAllWorkingSets();

    for (IWorkingSet aWorkingset : allWorkingSets) {

        IAdaptable[] elems = aWorkingset.getElements();
        System.out.println("Working set " + aWorkingset.getName() + " has "+ elems.length + " projects.");
        for (IAdaptable elem : elems) {
                System.out.println("Working set " + aWorkingset.getName()+ " contains " + elem.toString());
        }
    }

简单来说，我想知道如何以与工作区项目相同或类似的方式从工作集中获取 IProject？

Answer 1

在每个 IAdaptable 元素上调用

IResource resource = (IResource)elem.getAdapter(IResource.class);

它将返回该元素代表的任何资源(某些工作集包含其他内容，因此结果可能为空)。

然后您可以调用

IProject project = resource.getProject();
