Changing project builder properties failed.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Right click a project.
2. Click Properties
3. Click "File synchronization"
4. Click "Enable FileSync builder for project"

What is the expected output? What do you see instead?
I expect it to get checked and remain so after eclipse restart.  I expect not 
to have to do a full resync every time I restart eclipse.  Instead I get an 
error box popup: "Changing project builder properties failed."

I have full permissions to the file on the filesystem.  I know .project files 
are special in that you can't do normal file operations to them as they are not 
valid windows filenames.  For example, I cannot create a .project file in 
explorer.  Perhaps there is a special method for modifying the project 
properties in eclipse.

Original issue reported on code.google.com by r...@ruslansivak.com on 30 Jan 2013 at 4:30

Apparently the issue is caused by the hidden attribute set on the .project 
file.  Taking that attribute off makes the error go away.

[GoogleCodeExporter]

So the root cause is that the hidden attribute was set, which is *not default* 
in Eclipse before 4.2.1. 

Can you please confirm that after creating a new project on Win32 (without 
using FileSync at all for project) the .project file has "hidden" attribute?

If yes, please report a bug against Eclipse 4.2.1 (and please let me know the 
bug number).

FileSync uses standard Eclipse API without directly writing any .project file, 
so I would expect other tools would have same problems with hidden .project 
files.

Thanks,
Andrey
