I have created free-style software project in Hudson.
I want to clone a public Git repository: git://github.com/bret/watir.git
Build fails with error message
It's worth noting that if the cloning process itself has an issue you will also see this problem. I have had issues with one of my boxes failing 4 out of 5 times on the initial clone of a large repository, and hudson kept throwing this error. A good way to verify this is the problem, and it's not Hudson being unable to find the git executable, is to clone the repository into the Hudson workspace manually, and then run a Hudson build: if Hudson is configured properly the build will succeed and report that there are no changes.
