Description

I tried to configure DocumentNodeStore to use FileDataStore with Sling Launchpad 8, as advised in [0].
For this I created in ${sling.home}/install the following configurations:

org.apache.jackrabbit.oak.plugins.segment.SegmentNodeStoreService.cfg
customBlobStore=true

org.apache.jackrabbit.oak.plugins.blob.datastore.FileDataStore.cfg
minRecordLength=4096
path=/some/path

When starting launchpad with java -jar org.apache.sling.launchpad-9-SNAPSHOT.jar -Dsling.fileinstall.dir=sling/install the following exception is thrown:

ERROR [CM Event Dispatcher (Fire ConfigurationEvent: pid=org.apache.jackrabbit.oak.plugins.blob.datastore.FileDataStore)] org.apache.jackrabbit.oak-core [org.apache.jackrabbit.oak.plugins.blob.datastore.FileDataStore(196)] Error during instantiation of the implementation object (java.lang.NoClassDefFoundError: org/apache/jackrabbit/core/data/DataStore)

The reason is that org.apache.jackrabbit/jackrabbit-data/${jackrabbit.version} bundle is missing from the provisioning model. Adding it solved the problem.
