Error:scalac: No 'scala-library*.jar' in Scala compiler classpath in Scala SDK s

IDEA在跑从网上下载的Maven新flink项目时，运行报：Error:scalac: No 'scala-library*.jar' in Scala compiler classpath in Scala SDK scala-sdk-2.11.11错误，就主要原因为idea找不到scala的编译环境 File>>Project Structure>>Libraries中删除默认的scala编译library，替换成本地的scala-sdk变量即可
