I have started using Sublime text as my preferred code editor (for JS, CSS, Coffee). But, I still rely on Eclipse for writing Java code because it auto-imports Java packages and auto suggests variables and method names from my custom class files.
Working on multiple editors throws in another problem: whenever I make a change in some file outside of Eclipse, the IDE does not silently reload. It shows a blank page saying 'The resource is out of sync. Press F5 to reload'. The message started annoying me soon as I had to switch back and forth often.
It is not just for the multiple editors. Even when I do a git pull, the resources go out of sync.
Then, I found a workaround for this. Eclipse provides a built-in option that auto reloads a resource if its out f sync. Here's how you can enable it.
Go to **Window -> Preferences -> General -> Workspace **and check the option 'Refresh using native hooks or polling'.
So, the next time when you try to open a out of sync file, the IDE will sync it for you (thus saving you a keystroke, one at a time 
).
