When having a build step of type Checkout and setting the checkout path to a sub directory of the workspace, that sub directory can now be cached between builds. This is useful to speed up checkouts of large projects with many files.

However when doing so, the Checkout step fails on subsequent builds because it tries to add a git remote that is already present (because the directory was cached).
