当我使用https://ci.apache.org/projects/flink/flink-docs-release-1.6/quickstart/scala_api_quickstart.html推荐的sbt模板创建项目时
sbt new tillrohrmann/flink-project.g8
当我尝试向scala API方法（过滤器，地图等）提供任何匿名函数时，出现以下错误。 ordinals.print（）工作正常。我不是flink scala repl中的不是，这只是正常的intellij scala repl。根据{{3}}，这应该可以，并且如果我要在集成测试中使用它（和StreamExecutionEnvironment），则需要工作。我知道CollectionEnvironment，它工作正常，但是使用StreamExecutionEnvironment并没有帮助。我已经在Windows和Linux的2个intellij环境中进行了尝试，都使用scala 2.11.12，flink 1.6.1和Java 8。
当然，执行环境文档是基于Java的-我需要使scala API正常运行的依赖项或导入项吗？

更新：从scalatest内部来看，ExecutionEnvironment.getExecutionEnvironment和StreamExecutionEnvironment.getExecutionEnvironment都可以正常工作，因此我不必担心。
