class java.lang.RuntimeException/error reading Scala signature of package.class: Scala signature package has wrong version

在用scala連接spark時，出現錯誤：

scalac: error while loading package, class file 'C:\Users\asus\.ivy2\cache\org.scala-lang\scala-library\jars\scala-library-2.13.7.jar(scala/reflect/package.class)' is broken
(class java.lang.RuntimeException/error reading Scala signature of package.class: Scala signature package has wrong version
expected: 5.0
found: 5.2 in package.class)

 

 是因為版本沖突的問題，編譯器添加scala的sdk版本與pom文件的版本一致

 

打開File>>Project Structure>>Global Librarier 添加和pom文件一致的版本即可

 

 運行成功

 

 最后，，用的spark版本是3.0
