In this call:
results = Peer.query("[:find [?artist-name ...] " +
" :in $ ?country [?reference ...] " +
" :where [(datomic.api/entid $ ?country) ?country-id] " +
" [?artist :artist/name ?artist-name] " +
" [?artist ?reference ?country-id]]",
db, Util.read(":country/BE"), Util.list(Util.read(":artist/country")));
I am getting the following error: java.lang.ClassNotFoundException: datomic.api, compiling:(NO_SOURCE_PATH:0:0)
Can you tell me what configuration I am missing?
