Conditional setup task for empty workspaces [message #1854880]

Is it possible to execute a setup task only on new workspaces, but skip it on existing workspaces.
My use case is applying a custom Java Formatter for every new workspace, but allow users to override it afterwards (and keep that setting even after a restart).

Although https://wiki.eclipse.org/Eclipse_Oomph_Authoring#Conditional_Tasks looks promising I haven't found a variable exposing the flag if a workspace is new or existing.

I can't think of a simple way. I thought maybe one use a file creation task for the file at <ws>/.metadata/.plugins/org.eclipse.core.runtime/.settings but that file is created to early already.

All I can think to make it simple is to define some new behavior where we create some file in the workspace metadata (or set some preference internally) if it doesn't already exist (or wasn't already set) and set some system property based on whether we created that file (set the preference) or not. Then that system property could be used as a filter. Of course that doesn't exist yet...

Thanks for the reply. I raised https://bugs.eclipse.org/bugs/show_bug.cgi?id=580752 to track this.
