Encoding save .settings folder already exists

[akberc]

I couldn't find an existing issue.

Workspace froze hard (setting up typechecker at 70% - which may be another issue) and I killed Eclipse and wiped out workspace metadata as Eclipse would not re-start.

On re-importing projects, a bunch of encoding prompts pop up (just an annoyance) and then three Ceylon projects could not save the encoding to Eclipse properties as the 'settings' folder already exists.

Maybe a co-incidence: These three were projects that were open prior to the crash. The rest of the Ceylon projects were closed.

Could not save encoding settings.

What I imagine happens here is that the workspace is out of sync with the file system. So Eclipse thinks the .settings folder is nonexisting when actually it exists. So refreshing everything from the InternalSynchronizeJob should solve the problem.

@akberc I have added some calls to refresh() that should fix the bug. However, I have not tried to actually reproduce the problem from your description. Can you check that it's really fixed? Thanks!
