Dependencies work fine in maven but not in sbt - maven

Question

In my scala project I have a dependency that works fine in my maven project, but throws an error in my sbt project.
In this specific case the dependency in my build.sbt is:
"com.sksamuel.elastic4s" % "elastic4s-xpack-security_2.11" % "5.1.5"
while in my pom.xml:
[...]
<properties>
<maven.compiler.source>1.6</maven.compiler.source>
<maven.compiler.target>1.6</maven.compiler.target>
<encoding>UTF-8</encoding>
<scala.version>2.11.8</scala.version>
<scala.compat.version>2.11</scala.compat.version>
<spark.version>2.1.0</spark.version>
</properties>
[...]

[...]
and the error shown is:
[trace] Stack trace suppressed: run 'last *:update' for the full output.

in fact the dependency doesn't exist.
But my question here is: Why in maven this issue doesn't show up? What does happen in maven that it doesn't in SBT ?

Answer 1

Add to build.sbt:
resolvers in ThisBuild += "elastic" at "https://artifacts.elastic.co/maven"
See Elastic documentation for gradle:
// Add the Elasticsearch Maven Repository
maven {
url "https://artifacts.elastic.co/maven"
}
