Hi,
when a depending project is build the dependent project should have
been and its index entries should be there.
can you elaborate on your usecase?

We are virtually showing merged content of two project (parent and child) in our custom "Package Explorer". Files from each project can reference file from other project. Child project files override parent project files.
As workaround I extracted logic from our containerManager.getVisibleContainers and I'm reusing it in validator without using container.getExportedObjects.
In our case container is file. And visible containers are visible files. It is implemented using extended AbstractAllContainersState.
I think problem was that Clean removes index and Build rebuild it so it is why validation of first built project was not working (because files from second project where not indexed yet). Probably this behavior it is ok for most use cases.

it builds project by project
Hi, I still have problem with this. You are right problem is cyclic dependency between projects. Is it maybe possible to change something that ResourceDescriptions are not taken from index so that it doesn't depend on build order.
I know it would be slower but I have only few files so even loading them to ResourceSet while resolving cross references would be ok for me I think.
Edit:
I fixed problem by extending ProjectAwareResourceDescriptionsProvider and loading dependent resources to ResourceSet and changing from ResourceDescriptionsProvider.NAMED_BUILDER_SCOPE to ResourceDescriptionsProvider.LIVE_SCOPE in LoadOptions so that ResourceDescription from ResourceSet are created.
For now it seams to work.
