[news.eclipse.platform] how to determine programmatically if auto-build

[Edoardo Comar <edoardoATenigmatecDOTnet@xxxxxxx>]

my plugin tests run with the default auto-build enabled.
i often do
1-  resource changes
2 - then need to wait for the build to finsih
3 - check the results.

I mimic 2 by manually invoking a build of the workspace
but I really would like just to wait until auto-build is completed.

how can I check that ?

do I need to temporarily add a resource listener that waits for an event 
of type POST_BUILD or is there a more straightforward way ?

TIA,
Edo
