Why can't eclipse properly build the .classpath?

Question

I am a LWJGL developer, and I use to develop for Mac OSX. I recently switched to a new computer, and I am finding it is very difficult to transfer my project properly.

After I installed eclipse, I imported my old project to my workspace. The project contained all the Jars I needed within it's lib folder, and I started to add them to my projects build path. After clicking 'OK' the build path window close, and a pop-up appeared with an error message; It read: "Cannot write .classpath file at D:\My Files\Programming\Eclipse Access is denied"

Now, the first thing I thought is, it must be the Windows 8.1 firewall. I completely turned off the firewall, and I got the same message. Could it possibly be because I am running my OS + All my runtime environments off a different hard drive, and it doesn't know what to do? Please help, I have a deadline of a lot of important work to do. I also apologize if my grammar is off, english is not my first language.

Note: I am the ONLY user of this computer, so I am also it's administrator.

It's not the firewall, looks like whatever user eclipse is running as does not have write permissions to the directory that the app is installed in. — Rob, Dec 01 '13 at 22:20
Windows 8 will not let you write to certain directories. For instance, I cannot write to C: I am also an administrator. — Gilbert Le Blanc, Dec 01 '13 at 22:26
Try restarting your computer. Maybe some other program is locking it and a reboot will flush it out. — MultiplyByZer0, Dec 02 '13 at 00:32

Try to uncheck the Hidden attribute for .classpath files in your projects.

I had to show the hidden files and then uncheck the hidden .classpath file. – juan Isaza Apr 29 '15 at 07:34

IMHO, the file is opened somewhere else. Another instance of Eclipse? Some text editor? Sometimes Windows think it IS opened somewhere else, while it is not. Then you have to reboot.

I had the same problem. Here is how I fixed it.

close the project
copy .classpath to classpath.txt
delete .classpath
open the project
refresh
edit the properties for the project ( this will create a good classpath )
edit .classpath & put your stuff back in from classpath.txt
save it (you should notice there was no error this time)

Why? I think windows got confused about the file .classpath thought it was open elsewhere perhaps

Create a new project > import > file system > browser > select project > uncheck the classpath checkbox.

It's going to solve your problem.
