Reproducible: Always

Steps to Reproduce:
On windows
1. Create a simple job that clones a git repos
2. Select the 'Wipe out workspace before build' flag
3. Build
4. The consoe log above appears and the job fails.

Without the flag the job succeeds

Fixed. The function makeFileWritable is not available for windows. So the fix is to guard the block on windows. 

I tested the fix on my Virtualbox Windows XP
