I'm trying to setup an ElasicSearch client using Scala. I'm new to Scala, so I'm following some online tutorials suggesting elastic4s-client-esjava. I've got that setup in my build.sbt with the rest of my library dependencies below:
name := "ElasticSearchService"
version := "0.1"
scalaVersion := "3.5.2"
libraryDependencies ++= Seq(
"org.postgresql" % "postgresql" % "42.3.1",
"nl.gn0s1s" %% "elastic4s-client-esjava" % "8.11.5",
"nl.gn0s1s" %% "elastic4s-core" % "8.11.5"
)
When I try to run sbt run I get an error sbt.librarymanagement.ResolveException: Error downloading nl.gn0s1s:elastic4s-client-esjava_3:8.11.5 NOT FOUND. I've verified that the packages and versions exist here: https://mvnrepository.com/artifact/com.sksamuel.elastic4s/elastic4s-client-esjava and https://mvnrepository.com/artifact/com.sksamuel.elastic4s/elastic4s-core. I'm wondering if something about my setup or configuration is incorrect. Before I added ElasticSearch library dependency the project was working fine (with the postgres dependency only).
Any assistance on how to resolve this would be much appreciated! The full error log is below for reference:

Yeah, sorry for not being clear. It seems at some point in time, the library changed owners from sksamuel; who used the domain / organization com.sksamuel.elastic4s to Philippus; who is using the domain / organization nl.gn0s1s.
(IIRC, this is actually quite recent, but is been a while since I looked at anything ElasticSearch related).
As such, newer versions are in the nl.gn0s1s space: https://mvnrepository.com/artifact/nl.gn0s1s/elastic4s-core and older versions are in the com.sksamuel.elastic4s space: https://mvnrepository.com/artifact/com.sksamuel.elastic4s/elastic4s-core
Thus, you can either use the latest version: 8.15.3 released in the nl.gn0s1s space.
Or use the version you originally posted; 8.11.5, but changing the space to com.sksamuel.elastic4s
IMHO, it is better to use the latest, but you may be following an outdated tutorial and as such it may be easier to stick with the version of that tutorial.
