Importing scala libraries with Maveen is refused, how to resolve this? - scala

Question

I am wrestling with importing required jar files and deploying them into scala projects after writing build.sbt script. Resolvers deny downloading any scala libraries from neither sonar and maveen 2 resolvers. My scala version is 2.13.0 and sbt is 1.6.1
after compiling sbt builds the program yields errors stated below.
download error: Caught java.io.IOException (Server returned HTTP
response code: 400 for URL:

Here is my build.sbt script which means error does'nt stem from syntax error.
lazy val commonSettings = Seq(
organization := "scala_REINFORCEMENTLEARNING",
organizationName:="trial",
scalaVersion := "2.13.0",

lazy val root = (project in file("."))
.settings(
commonSettings,

Look's like you've got an extra whitespace in your version number:
https://repo1.maven.org/maven2/org/scala-lang/scala-library/2.13.0/scala-library-2.13.0 .pom
Fix the Scala version in your build.sbt and it should be it.
