1. 异常说明

今天写了一段 Flink 窗口 function 的代码运行的时候抛出一个 NumberFormatException: Not a version: 9 的异常，异常信息如下：

2. 异常原因

版本冲突导致 flink 在寻找 guava 版本的时候 shaded 错误导致此异常。

编译器引用的scala-sdk版本是2.11.8

但是maven引入的scala相关包2.11.12

3. 解决办法

可以在maven中将引入的 Scala 版本改为 2.11.8。

<dependency>
    <groupId>org.scala-lang</groupId>
    <artifactId>scala-library</artifactId>
    <version>2.11.8</version>
</dependency>
<dependency>
    <groupId>org.scala-lang</groupId>
    <artifactId>scala-compiler</artifactId>
    <version>2.11.8</version>
</dependency>
