stacktrace

I am trying to run an API use scan as described in:
http://wiki.eclipse.org/PDE/API_Tools/Resources#Running_an_API_use_scan_.28commandline.29

But I am blocked by a NPE apparently due to PDE Core not being initialized (see attached stacktrace).

I get this exception both in my local installation when running ant in a separate JRE, and on the Hudson instance on build.eclipse.org, but not when running ant in the same JRE as my Eclipse instance (in this case, I suppose Eclipse already properly initialized the bundles).

When the static variable LocalTargetHandle#LOCAL_TARGET_CONTAINER_PATH is initialized, PDECore#inst is still null, leading to a NPE in "PDECore.getDefault().getStateLocation()"

What I don't understand is that the wiki page describes running the API scan like a standard Java application. Shouldn't it be run as an Eclipse application instead? Otherwise, how are the bundles supposed to be started if there is no Equinox running?

This is a known issue and has been fixed in bug 342193.

I am not sure what you mean. The section describes how to run the tasks from the commandline; there is no Java nor running Eclipse involved at all.

It *could* be run that way as well. But we also support running the Ant tasks from the commandline using only Ant like the following:

   root%>ant -buildfile <build file name>

The bundles do not get started in the commandline case. The cause of this issue is that there is no OSGi running and the target platform service was not working as expected without OSGi.
