Using ions with Leiningen

Client API
1

Hi folks. Has anyone deployed with ions from a Leiningen project? The tutorial only describes the process with deps.edn. I’m trying to apply the same steps to my project.clj without luck.

I get the following dependency synchronization error on the ion when trying to declare ion-dev dependencies:

Could not find artifact com.datomic:ion-dev:jar:0.9.290 in central (https://repo1.maven.org/maven2/)

Failed to read artifact descriptor for com.datomic:ion-dev:jar:0.9.290

This could be due to a typo in :dependencies, file system permissions, or network issues.

I had no problem establishing a Datomic connection from my project and transacting to my db, so I don’t think there is a problem with my setup.

My project.clj atm:

  :target-path "target/%s"
  :profiles {:uberjar {:aot :all :jvm-opts ["-Dclojure.compiler.direct-linking=true"] :dev {:main clojure-api.core/-dev-main}}})

Any thoughts? I’m probably missing something quite obvious, but difficult to tell without seeing an example in Leiningen :slight_smile:

Alternatively, has anyone deployed an API that transacts on Datomic without ions?
