问题

在spark集群运行scala程序报错

Error:scalac: error while loading package, class file 'C:\Program Files (x86)\scala\lib\scala-library.jar(scala/collection/immutable/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)

原因maven scala版本要和scala sdk一致

scala sdk版本为2.13.8

解决问题

修改maven依赖

<dependency>
			<groupId>org.scala-lang</groupId>
			<artifactId>scala-library</artifactId>
			<version>2.13.8</version>
		</dependency>
