Error:scalac: missing or invalid dependency detected while loading class file ‘ScalaCaseClassSeriali

一、问题描述

用IDEA编写flink的scala程序，编译没有错误但是运行出错，日志如下：

Error:scalac: missing or invalid dependency detected while loading class file 'ScalaCaseClassSerializer.class'. Could not access type SelfResolvingTypeSerializer in object org.apache.flink.api.common.typeutils.TypeSerializerConfigSnapshot, because it (or its dependencies) are missing. Check your build definition for missing or conflicting dependencies.

 

二、问题原因

我找了半天也不知道ScalaCaseClassSerializer.class是在哪个包，但是有个提示org.apache.flink.api.common.typeutils

它对应本地仓库的jar包有问题

E:\ProgramFiles\maven_lib\org\apache\flink\flink-core\1.9.0\flink-core-1.9.0.jar
