While checking the Refresh using native hooks or polling
Eclipse is searching for changes on files on the whole workspace (all the projects under the workspace).
Is there a way to narrow the scope to only one project from the workspace? I'm editing the .css/.js/.html files using SublimeText (3rd party application), and want to see the changes on my server that Eclipse managed, but I have 10 projects under the workspace and Eclipse keep searching for updates on them also.
No, the automatic refresh is always for the entire workspace.
You can manually refresh a single project using 'File > Refresh' with the project selected.
