Writing to a file with the hidden attribute (Windows) [message #314775]

Hi,

I am running Eclipse 3.2.2 under Windows.

I have written a plugin that is using IFile#setContents() to write to a file in
a project. One of my users is getting a CoreException "Could not write file".

It turns out that the file has the 'hidden' attribute set, although it is writable.

Q1. How can I detect if this attribute is set, and thus prevent the error
Q2. Why does this error occur anyway? The file is writable, it is just hidden.

Thanks,

you need to do something like this to reset the attribute:

+ ResourceAttributes descriptionFileAttributes = descriptionFile.getResourceAttributes();
+ descriptionFileAttributes.setHidden(false);
+ descriptionFile.setResourceAttributes(descriptionFileAttributes);

Sun thought if the file is hidden it is effectively write protected, because a user would not be able to see the file from a list. The problem is this only was the intent of windows for it own internal files and not for the user.
Sun had a bug report to get this fixed after version 1.5 of Java. Java is now 1.8. Now, that Oracle has take over, I don't think this will ever be changed.
