Fix Unknown Artifact Warning in IntelliJ IDEA
Have you ever been frustrated by "Unknown Artifact" warnings underneath dependencies in a build.sbt file when browsing it in IntelliJ IDEA? You're not alone. Succinctly, this warning is a result of IntelliJ IDEA not being able to resolve dependencies from the Coursier cache. Since recent versions of SBT utilize Coursier by default, you must explicitly inform IntelliJ IDEA to not use it in order to remove the warnings in IntelliJ IDEA.
