My first response is: huh?
You are totally not supposed to do this...
Starting Worklight 6.1, after a change in any of an application's web resources (HTML, JS, CSS, images, ...), after the initial deployment of the app (Run As > Run on Worklight Development Server) you no longer even need to re-build the app.
When you preview the app via Worklight Console, all you need to do is to refresh the browser window. That's it.
You most definitely should not delete the app from Worklight Console or "Clean from Eclipse".
That said, if you are talking about previewing the "Common web resources" option in Worklight Console, what you may want to do (hopefully as a one-time action) is to:
- Close Eclipse
- Locate your temp folder (Windows, OS X)
- Delete the
wlBuildResources
folder (optionally wlPreview
folder as well)
- Open Eclipse
- Re-build
Should work.
