Apache flink 在flink-streaming-scala_2.11模块中运行流字计数时编译错误

我使用Intellij Idea从git克隆Flink项目

我能够在模块

flink-examples-batch_2.11

中成功运行批处理计数

org.apache.flink.examples.scala.wordcount.wordcount

但是，当我尝试在模块

flink-examples-streaming_2.11

中运行stream word count

org.apache.flink.streaming.scala.examples.wordcount.wordcount

时，出现了几个编译错误：

我不确定那里出了什么问题，有人能帮忙吗？谢谢

您能否澄清您使用的是哪个版本的Flink，以及您是如何尝试运行流媒体字数统计示例的？谢谢@DavidAnderson的回复。I git从github（主分支）克隆最新代码，并使用intellijidea作为Maven项目打开它，然后直接在intellijidea中运行它。我能够运行批处理模式字数计数：
