Yes, the variable comes from the workspace task which is only in the
project catalog.

This issue has come up before. Look at the thread titled "Executing
ResourceCreationTask after workspace switch" started "29/09/2015" .
The conclusion from that is that
${osgi.instance.area|trimTrailingSlashes} gives you a URI that is the
workspace location in any running IDE, so you can rely on that in any
task; not however that the task should not perform at bootstrap time,
because there it specifies the workspace of the installer itself, which
has no workspace.

Any task specified in a project setup can rely on this. The issue is
that you want tasks in the user.setup, and that can apply everywhere
and even want to to apply to some new workspace that's opened that
hasn't been setup by Oomph. So best to use the advanced properties on
your task so that it doesn't perform at bootstrap time.
