> Starting with Flink 1.7, there's lack of `runtime.testutils.MiniClusterResource` class in `flink-test-utils` distribution.
> Steps to reproduce (Scala code)
> build.sbt
> {code}
> name := "flink-17-test-issue"
> organization := "x.y.z"
> scalaVersion := "2.11.12"
> val flinkVersion = "1.7.0"
> libraryDependencies ++= Seq(
>   "org.apache.flink" %% "flink-streaming-scala" % flinkVersion % Provided,
>   "org.scalatest" %% "scalatest" % "3.0.5" % Test,
>   "org.apache.flink" %% "flink-test-utils" % flinkVersion % Test
> //  ,"org.apache.flink" %% "flink-runtime" % flinkVersion % Test classifier Artifact.TestsClassifier
> )
> {code}
> test class:
> {code}
> class SimpleTest extends AbstractTestBase with FlatSpecLike {
>   implicit val env: StreamExecutionEnvironment = StreamExecutionEnvironment.getExecutionEnvironment
>   env.setStreamTimeCharacteristic(TimeCharacteristic.EventTime)
>   env.setParallelism(1)
>   env.setRestartStrategy(RestartStrategies.noRestart())
>   "SimpleTest" should "work" in {
>     val inputDs = env.fromElements(1,2,3)
>     inputDs.print()
>     env.execute()
>   }
> }
> {code}
> Results in:
> {code}
> A needed class was not found. This could be due to an error in your runpath. Missing class: org/apache/flink/runtime/testutils/MiniClusterResource
> java.lang.NoClassDefFoundError: org/apache/flink/runtime/testutils/MiniClusterResource
> ...
> Caused by: java.lang.ClassNotFoundException: org.apache.flink.runtime.testutils.MiniClusterResource
> 	at java.net.URLClassLoader.findClass(URLClassLoader.java:381)
> 	at java.lang.ClassLoader.loadClass(ClassLoader.java:424)
> 	at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:349)
> 	at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
> 	... 31 more
> {code}
> This can be fixed by adding flink-runtime distribution with test classifier into dependencies list.
