如何为Scala/javamaven混合项目自动配置Scala方面?

如何让IntelliJ在混合Scala和Java源代码的Maven项目中自动配置Scala方面?

编译 运行测试 两者都从命令提示符和 无法编译Scala文件 请在Scala方面指定编译器 .

项目目录结构:

MixedJavaScala
│   MixedScalaJava.iml
│   pom.xml
│
└───src
    ├───main
    │   ├───java
    │   │       HelloJava.java
    │   │
    │   └───scala
    │           HelloScala.scala
    │
    └───test
        ├───java
        │       TestJava.java
        │
        └───scala
                ScalaSpec.scala

上市公司 :

public class HelloJava {}

海洛斯卡拉

class HelloScala

上市公司 测试java.java :

public class TestJava
{
    @org.junit.Test public void example() {}
}

上市公司 鳞片 :

class ScalaSpec extends org.specs.Specification {
  "nothing interesting should happen" in {}
}
