How can the Google Cloud Datastore Emulator verify our datastore-index.xml?

Question

We use the Google Cloud Datastore Emulator. It autogenerates indexes.yaml. But as we did with the old Google Plugin for Eclipse, we want to get missing-index messages in the local development environment, and not later in cloud deployment. So, we want the Emulator to use our manually-maintained datastore-indexes.xml

How do we configure the use of a specific datastore-indexes.xml in the Google Cloud Datastore Emulator? I don't see any relevant command-line switches in the help text.

EDIT:

My answer was based on the dev_appserver emulator, not the current one. After running some tests, it appears that the emulator only has endpoints for a subset of the Datastore API methods, and index building (nor export/import for that matter) are available.

Leaving my previous answer to avoid repeated answers with the same wrong info:

According to the docs, if autoGenerate="false" is in your datastore-indexes.xml, the development server should ignore the contents of WEB-INF/appengine-generated/datastore-indexes-auto.xml.

I think this might be what you're looking for, although I have not yet tested it.
