Eclipse: how to refresh the current project programmatically

Question

I'm building an eclipse plugin in which I'm going to create a new file in my project. Is there a way to refresh the current project?

I know that I can have a reference to all the project by calling

ResourcesPlugin.getWorkspace().getRoot().getProjects()

And the iterate among them and use

IResource.refreshLocal()

However this approach is not the best one, especially if the user have a lot of projects.

An alternative would be explore the project for checking if the new file is present or not but I would avoid it.

Answer 1

It's a whole lot easier to refresh at the project level.

IProject project = root.getProject(currentProjectName);
project.refreshLocal(IResource.DEPTH_INFINITE, null);

True, this might be inefficient, but you're sure that the whole project is refreshed.

Answer 2

It's not neccessary to call refreshLocal if you create the file with the workspace API, see org.eclipse.core.resources.IFile.create(InputStream, boolean, IProgressMonitor)
