I'm started using Google Eclipse Plugin, on Eclipse Indigo, to edit apps script and everything is working as expected, except that everytime I save a file, I get this popup the warning:
The file is shared but nobody else is editing or even opened on the web.
Any ideas?
I figured out what was happening.
Mac OS X and Eclipse Indigo
The problem was because of the Text File Encoding. On Mac OS X with Eclipse Indigo the default Text File Encoding is set to MacRoman. I suppose Apps Scripts are in UTF-8. When I set the default Text File Encoding to UTF-8 the problem was gone.
Mac OS X Mavericks and Eclipse Kepler
Default text encoding is already set to UTF-8.
To fix set Default Encoding
= UTF-8
in Preferences > General > Content Types > Text > JavaScript Source File > Apps Scripts Source file.
