How to convert from File to IFile in java, for files outside the project?

问题

Normally, this code is used for converting from File to IFile:

IWorkspace workspace= ResourcesPlugin.getWorkspace();    
IPath location= Path.fromOSString(file.getAbsolutePath()); 
IFile ifile= workspace.getRoot().getFileForLocation(location);

But this only works for java files within the project. How can I get the IFile when File file is not in the workspace (not in the project)?

回答1:

IResource and its child IFile were originally meant to be used only for resources located in the workspace. See the Javadoc for IResource.

However, since Eclipse 3.3 there is support for external files as well, see this Eclipse Wiki page.

回答2:

I needed this for using the Binding Resolutions from the Eclipse AST framework. But apparently, this is not possible - for anyone who need it, check this site:
