I am trying to program in Clojure and am using the stand alone IDE Counterclockwise. I do not know if this is an error with my computer or with the program itself. I uninstalled this program and reinstalled it because there were some issues with libraries, so I thought reinstalling it would ensure the correct installation of libraries. When I open a new copy of Counterclockwise and try to run some of my programs, it gives me this error when running clojure's REPL

This giant mass of an error, I have read, apparently refers to the folders that my projects are in. I would greatly appreciate if anyone can shed some light on this issue as I have no idea what the problem is as all this is foreign to me, Thanks!!!
                I am getting the same error. This link helped me (groups.google.com/forum/#!topic/clojuredev-users/gYuFnFPqVOY). I updated counterclockwise within eclipse and it seems to work.

I just had a similar problem in my windows system, and solved it by making sure that the %TEMP% was pointing to a real existing folder.
    Exception in thread "Thread-3" java.io.IOException: The system cannot find the path specified
    at java.io.WinNTFileSystem.createFileExclusively(Native Method)
    at java.io.File.createTempFile(Unknown Source)
Example: 
In my setup I am using git-bashfor command-line, so I checked for the presence of the %TEMP% environment by this command:
echo $TEMP
This resulted in /d/Users/username/AppData/Local/Temp. Then I verified that this did not point to an existing folder by 
cd $TEMP
which resulted in failure. I fixed the problem by
mkdir /d/Users/username/AppData/Local/Temp
I had a slightly different case as I need to bypass lein.bat and just run the lein executable jar to launch lein. I got things working from the command line, but not when I was launching it from a Java ProcessBuilder, so the temp folder must have been different for these cases. You can actually specify the temp folder you want by setting a java System property: java.io.tmpdir
In my case, the following worked to launch a lein app:
java -cp leiningen-2.5.3-standalone.jar -Djava.io.tmpdir=C:\Temp clojure.main -m leiningen.core.main run
(the above is the equivalent of running lein run)
