problem with resolving apache math4 library in scala

I created a simple Scala project to use with apache commons-math4 dependency. The content of build.sbt is the following.

name := "math4test"
version := "0.1"
scalaVersion := "3.0.2"

resolvers += ("apache_snapshots" at "https://repository.apache.org/content/repositories/snapshots/").withAllowInsecureProtocol(true)
libraryDependencies += "org.apache.commons" % "commons-math4" % "4.0-SNAPSHOT"

The sbt fails to resolve a number of dependencies for math4:

[error] (update) sbt.librarymanagement.ResolveException: Error downloading org.apache.commons:commons-numbers-rootfinder:1.0-SNAPSHOT
[error]   Not found

You should not rely on SNAPSHOT dependencies: they are not stable, don't provide a reproducible build and are not kept forever on repositories.

At the time of writing this answer, the latest published version 4.0-SNAPSHOT of commons-math4 depends on a version 1.0-SNAPSHOT of commons-numbers-rootfinder which is not available anymore (1.1-SNAPSHOT does exist: https://repository.apache.org/content/repositories/snapshots/org/apache/commons/commons-numbers-rootfinder/).
