------------------------------------
Summary: flink-test-utils dependency issue
Key: FLINK-11201
URL: https://issues.apache.org/jira/browse/FLINK-11201
Project: Flink
Issue Type: Bug
Components: Tests
Affects Versions: 1.7.0
Reporter: eugen yushin
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:

{code}
This can be fixed by flink-runtime distribution with test classifier.
