Unit test have Error "could not find implicit value for evidence parameter"

[Min Tu via user]

Hi,

I have downloaded the flink code and the build works fine with following
command

mvnw install -DskipTests -Dcheckstyle.skip

Then I try to run the unit test code in IntelliJ, but got following error:

/Users/mintu/ApacheProjects/flink/flink-scala/src/test/scala/org/apache/flink/api/scala/DeltaIterationSanityCheckTest.scala:34:41
*could not find implicit value for evidence parameter of type*
org.apache.flink.api.common.typeinfo.TypeInformation[(Int, String)]
    val solutionInput = env.fromElements((1, "1"))

Please advise.

Thanks in advance
