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

Hi,
you don't have to do that. Next time you can try "Invalidate Caches..."
under the File menu in Intellij Idea.
Best regards,

Thanks a lot !! I have removed the .idea folder and the unit test works.

Hi Min Tu,
try clean install to make sure the build starts from scratch. Refresh maven
modules in IntelliJ after the build. If that doesn't work, try invalidating
IntelliJ caches and/or reimporting the project (remove .idea folder).
Best,
Alexander Fedulov

What version of scala are you using?
Depending on the build you are using you may be using 2.11 or 2.12. The
version on your maven build files needs to be consistent across your system.
