Why am I getting this error when running Scala 2.1

I am getting the following error when I try to run tests in IntelliJ (2019.1), Scala IntelliJ plugin v2019.1.8, with Scala 2.13:

Exception in thread "ScalaTest-dispatcher" java.lang.NoSuchMethodError: scala.collection.JavaConverters.seqAsJavaListConverter(Lscala/collection/Seq;)Lscala/collection/convert/Decorators$AsJava;

The following are my Gradle dependencies:

dependencies {
    implementation 'org.scala-lang:scala-library:2.13.0'

    testImplementation 'org.scalatic:scalatic_2.13:3.0.8'
    testImplementation 'org.scalatest:scalatest_2.13:3.0.8'
}

When I change the dependencies to Scala 2.12.x, the tests execute correctly in IntelliJ without error. What is going on here?

Update: This has been fixed in plugin version 2019.1.9.

It is possible IntelliJ Scala plugin needs to be updated for 2.13. Meanwhile try workaround by selecting the checkboxes Use sbt and Use UI with sbt under test's Edit configuration.... According to Dmitrii Naumenko:
