Eclipse应用程序中的WorkSpace

Question

I am creating a standalone eclipse application and I need to acquire my workspace from the application. I don't want an Eclipse plugin as it wont solve my purpose.

IWorkSpaceRoot root = ResourcesPlugin.getWorkspace().getRoot();

But this is gives me an exception as the workspace is closed. Either my current workspace or any new workspace which could be accessed using a standalone application would solve my purpose.

Answer 1

Does Manifest.MF contain the org.eclipse.core.resources in the Require-bundle of your plugin?

And do you launch your Application as a plugin ? (not as a 'Java Application')

You can access the workspace from the resources plugin class (defined in org.eclipse.core.resources ).

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.

See Book for more details.

As a Java application, you cannot use ResourcesPlugin functions. So you need to access resources through classic File resources.

Answer 2

I use the below dirty workaround for this issue. You will need to manually updated the configuration for your RCP standalone.

1. Open the ' config.ini ' file located in the ' configuration ' folder (under your project location).
2. Edit the last line in the config.ini file : osgi.instance.area.default=<Workspace Loc>
3. Replace the in the line with the location of your workspace.
   eg: osgi.instance.area.default=D:/WorkspaceFolder/WorkspaceNew

Important: Forward Slash (/) should be used as separator when specifying the workspace.
