----------------------------------------------------------------
The problem is that when we don't have an existing project, a Maven project
stub ('standalone-pom') is used for which no basedir is specified. Therefore we
get a NPE when the code expects a basedir to be defined. See
CheckoutProjectFromScm.performCheckout().
