使用idea创建scala maven项目非常简单，只需要在普通maven项目上添加相关插件即可
```java
<properties>
<maven.compiler.source.version>1.8</maven.compiler.source.version>
<maven.compiler.target.version>1.8</maven.compiler.target.version>
<encoding>UTF-8</encoding>
<scala.version>2.12.12</scala.version>
<scala.compat.version>2.12</scala.compat.version>
</properties>
```bash
```java
<build>
<plugins>
<plugin>
