Flink学习9：配置idea开发flink-Scala程序环境

1.下载安装idea

我的CSDN资源中有ideeeeeeaaaaa

2.安装Scala插件

3.新建项目，并增加Scala框架

3.1下载Scala框架

Scala 2.12.16 | The Scala Programming Language

下载MSI结尾的

3.2 新建Maven项目,并设置为Scala

新建项目

新建maven项目

增加Scala框架

ps: 如果 Scala SDK没有的话，就点击create –> download –> 选择对应的Scala版本(主要是和spark或flink, hadoop版本匹配)

测试

看到这个成功

新建一个Scala类

编写测试类：

4.配置pom.xml文件

ps:随着时间的流逝，插件的版本会发生变化。

可以根据情况改变插件、依赖等版本。

比如：编译用的scala-maven-plugin 插件。可以百度搜索scala-maven-plugin，

然后圈中的3个地方就是需要改写的。
