Hi!
I would like to add the FileSystemImportWizard to my application. I would
like to init this in such way, that it should point out to my
plugin's .metadata directory. Is it possible?
According to the documention about FileSystemImportWizard, this class should
be invoked as follows:
IWizard wizard = new FileSystemImportWizard();
wizard.init(workbench, selection);
WizardDialog dialog = new WizardDialog(shell, wizard);
dialog.open();
The 'selection' attribute should point out to the .metadata directory:
final IWorkspaceRoot myWorkspaceRoot =
ResourcesPlugin.getWorkspace().getRoot();
final IPath metadataPath =
MyPluginActivator.getDefault().getStateLocation();
StructuredSelection selection = new
StructuredSelection(myWorkspaceRoot.getFolder(metadataPath)) ;
The problem is, that this is not working. I have investigated the source
code of the FileSystemImportWizard class and it works as follows:
Object firstElement = selection.getFirstElement();
IResource res = null;
if (firstElement instanceof IAdaptable) {
Object resource = ((IAdaptable) firstElement).getAdapter(IResource.class);
if(resource != null) {
res = (IResource) resource;
}
}
Unfortunately, res.isAccessible() == false
How to get IResource instance of the .metadata directory, which is
accessible?
Best regards, Pawel.

Could you explain what you are trying to accomplish by accessing the
..metedata directory? .metadata is not a resource, which is your problem.

So this is not possible, isn't it?
I would like to provide to users some files immediately after installing my
plugin (without creating any projects in a workspace). These files have to
be available for other plugins (which means, they have to be accessable via
IFile interface). Therefore I store them in the .metadata directory.
Parhaps this is not the best solution. (I will be glad to hear other one).
However, it is probably too late to change my architecture.
best regards, Pawel.

If you want to use resources (that is any subclass of IResource), then
you must store the resources in projects. You can't access anything
inside the .metadata directory because that's not part of what's
possible with resources.
You would have to create some kind of project to hold these files. Note
that with EFS and/or linking eclipse allows you to have the backing
store of the projects anywhere you want (like in a zip file, or the
plugin itself).
If these files don't change, you might consider just accessing them
directly from the JAR file of your plugin, by using the Java resource
mechanism (unrelated to the eclipse resource mechanism).
Hopefully this helps a little.

This helped me a lot, thank you! Pawel.
