title: How to clear sbt cache?
body: <p>I'm using <code>sbt 1.3.9</code> and I need to update some libraries that have changed its code but the version stays the same. When I tried to run <code>sbt update</code> command nothing happened the library not downloaded.
  I have <code>sbt.build</code> file that looks like the following:</p>
  
  <pre><code>name := """project name"""
  organization := "com.example"
  
  version := "1.0-SNAPSHOT"
  
  lazy val root = (project in file(".")).enablePlugins(PlayJava)
  lazy val usr = sys.env("MVN_USER")
  
  scalaVersion := "2.13.1"
  javacOptions ++= Seq("-source", "11", "-target", "11")
  resolvers ++= Seq(
    "Jfrog Artifacts".at("https://artifactory.jfrog.com/")
  )
  credentials += Credentials(
    ...
  )
  updateOptions := updateOptions.value.withCachedResolution(false)
  updateOptions := updateOptions.value.withLatestSnapshots(false)
  libraryDependencies ++= Seq(
    guice,
    javaWs,
    ehcache,
    "com.google.api-client" % "google-api-client" % "1.30.7",
    "org.apache.commons" % "commons-lang3" % "3.9",
    "redis.clients" % "jedis" % "3.2.0"
  )
  </code></pre>
