If we start on a green field (only kas is available) we can't setup the environment directly. So in this case the order is SetupProxy, ReposFetch, ReposCheckout and then SetupEnvironment. Only if the --keep-config-unchanged flag is provided directly go from SetupProxy to SetupEnvironment. Signed-off-by: Daniel Wagner <daniel.wagner@siemens.com>
