I get this error when trying to get the workspace through ResourcesPlugin:
尝试通过ResourcesPlugin获取工作区时出现此错误:
java.lang.IllegalStateException: Workspace is closed.
at org.eclipse.core.resources.ResourcesPlugin.getWorkspace(ResourcesPlugin.java:339)
The code generating this is:
生成它的代码是:
IWorkspace ws = ResourcesPlugin.getWorkspace();
Can you please help with this problem?
你能帮忙解决这个问题吗?

Does your Manifest.MF contain the org.eclipse.core.resources in the Require-bundle section ?
您的Manifest.MF是否包含Require-bundle部分中的org.eclipse.core.resources?
And do you launch your test as a plugin ? (not as a 'Java Application')
你作为一个插件启动你的测试? (不是'Java应用程序')

As mentioned in the "Resources and the file system" help page,
如“资源和文件系统”帮助页面中所述,
You can access the workspace from the resources plug-in class (defined in
org.eclipse.core.resources).您可以从资源插件类(在org.eclipse.core.resources中定义)访问工作空间。
When the resources plug-in is not running, the workspace exists solely in the file system and is viewed or manipulated by the user via standard file-based tools. Let's look at what a workspace looks like on disk as we explain the resources plug-in API.
当资源插件未运行时,工作空间仅存在于文件系统中,并由用户通过基于标准文件的工具查看或操作。在我们解释资源插件API时,让我们看一下工作区在磁盘上的样子。
From this book:
从这本书:
The workspace directory, regardless of the name defined with the
-datainvocation option, has two roles:无论使用-data调用选项定义的名称,工作空间目录都有两个角色:
- it acts as the parent for the
.metadatadirectory它充当.metadata目录的父级
- and as the default location for projects
并作为项目的默认位置
the workspace can contains projects only when:
工作区只能在以下情况下包含项目:
- the
org.eclipse.core.resourcesplugin is included in the configuration andorg.eclipse.core.resources插件包含在配置中
- and appropriately started from the workbench
并从工作台适当地开始
this is automatic from an IDE configuration based on the
org.eclipse.ui.ide.workbenchapplication.这是基于org.eclipse.ui.ide.workbench应用程序的IDE配置自动完成的。

另请参阅此主题并记住:
the workspace is a different workspace from the runtime-workspace that's used for testing plugins. When you do Run on an Eclipse PDE environment, it creates a new workspace which is completely empty.
工作空间是与用于测试插件的运行时工作空间不同的工作空间。在Eclipse PDE环境中运行时,它会创建一个完全为空的新工作空间。
The testing workspace root can be specified through the "-data" launching option.
可以通过“-data”启动选项指定测试工作区根目录。
If you want to access a file, your best bet is to include it in the plugin itself, and then use
getClass().getResourceAsStream("/myfile.txt")to get anInputStreamthat you can read the contents for.如果你想访问一个文件,最好把它包含在插件本身,然后使用getClass()。getResourceAsStream(“/ myfile.txt”)来获得一个可以读取内容的InputStream。

Try calling Plugin.getStateLocation() in the plugin, it should cause the workspace to be created for you. Without this, you can't save any preferences either. http://dev.eclipse.org/newslists/news.eclipse.platform/msg45020.html
尝试在插件中调用Plugin.getStateLocation(),它应该会为您创建工作区。如果没有这个,你也无法保存任何偏好。 http://dev.eclipse.org/newslists/news.eclipse.platform/msg45020.html
Err, sorry -- I just completed necroed this question by accident :)
