IDEA下meavn开发scala程序

IDEA下meavn开发scala程序，一般有两种方式：

第一种：安装好Scala, 通过IDEA Scala插件进行开发
第二种：使用maven插件包进行开发

一、通过IDEA Scala插件开发

1. 安装Scala插件

2. 创建 Maven 工程，Add Frameworks Support(Scala)

2.1 创建项目名称为`scala-plugin`的maven项目

2.2 Add Frameworks Support

右键点击工程目录，选择Add Frameworks Support

选择Scala，点击确定

这样，就可以右键新建Scala文件了

1.3 添加scala源目录，进行开发

在src/main下新建scala目录，右键 --> Make Directory as --> Source Root

在scala目录下新建Test.scala,运行进行验证

二、通过maven plugin插件进行开发

1. 添加scala依赖

<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>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <java.version>1.8</java.version>
    <scala.version>2.11.8</scala.version>
</properties>


<dependencies>
    <dependency>
        <groupId>org.scala-lang</groupId>
        <artifactId>scala-library</artifactId>
        <version>${scala.version}</version>
    </dependency>
</dependencies>

2. 添加scala-maven-plugin插件

<build>
    <plugins>
        <!-- This plugin compiles Scala files -->
        <plugin>
            <groupId>net.alchim31.maven</groupId>
            <artifactId>scala-maven-plugin</artifactId>
            <executions>
                <execution>
                    <id>scala-compile-first</id>
                    <phase>process-resources</phase>
                    <goals>
                        <goal>add-source</goal>
                        <goal>compile</goal>
                    </goals>
                </execution>
                <execution>
                    <id>scala-test-compile</id>
                    <phase>process-test-resources</phase>
                    <goals>
                        <goal>testCompile</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>
                <scalaVersion>${scala.version}</scalaVersion>
            </configuration>
        </plugin>
    </plugins>
</build>
