Problems with https://juxt.pro/crux/docs/configuration.html#standalone

Starting with a new Edge component:

To add Crux as a project dependency:

Adding:

juxt/crux {:mvn/version "19.06-1.6.0-alpha"}

fails because the specified version does not exist.

Adding:

juxt/crux {:mvn/version "19.06-1.1.0-alpha"}

as indicated on the CRUX github page at https://github.com/juxt/crux works.

Start the standalone system:

Executing:

(def ^crux.api.ICruxAPI system
  (crux/start-standalone-system {:kv-backend "crux.kv.memdb.MemKv"
                                 :db-dir "data/db-dir-1"}))

results in

Syntax error (IllegalStateException) compiling def at (REPL:1:1).
system already refers to: #'dev-extras/system in namespace: dev

Executing (note the name change from system to csys):

(def ^crux.api.ICruxAPI csys
  (crux/start-standalone-system {:kv-backend "crux.kv.memdb.MemKv"
                                 :db-dir "data/db-dir-1"}))

results in

Execution error - invalid arguments to crux.bootstrap.standalone/start-standalone-system at (standalone.clj:85).
{:kv-backend "crux.kv.memdb.MemKv", :db-dir "data/db-dir-1"} - failed: (contains? % :event-log-dir)

The following executed with only a couple of warning logs:

(def ^crux.api.ICruxAPI csys
  (crux/start-standalone-system {:kv-backend "crux.kv.memdb.MemKv"
                                 :db-dir "data/db-dir-1"
                                 :event-log-dir "data/event-log-dir"}))

which were:

14:20:46.259 WARN  crux.kv.memdb [main]
Using fsync on MemKv has no effect.
14:20:46.259 WARN  crux.kv.memdb [main]
Using sync? on MemKv has no effect. Persistence is disabled.
