IDEA下meavn開(kāi)發(fā)scala程序，一般有兩種方式：

• 第一種：安裝好Scala, 通過(guò)IDEA Scala插件進(jìn)行開(kāi)發(fā)

• 第二種：使用maven插件包進(jìn)行開(kāi)發(fā)

一、通過(guò)IDEA Scala插件開(kāi)發(fā)

1. 安裝Scala插件

2. 創(chuàng)建 Maven 工程，Add Frameworks Support(Scala)

2.1 創(chuàng)建項(xiàng)目名稱(chēng)為scala-plugin的maven項(xiàng)目

image

2.2 Add Frameworks Support

右鍵點(diǎn)擊工程目錄，選擇Add Frameworks Support

image

選擇Scala，點(diǎn)擊確定

image

這樣，就可以右鍵新建Scala文件了

image

1.3 添加scala源目錄，進(jìn)行開(kāi)發(fā)

在src/main下新建scala目錄，右鍵 --> Make Directory as --> Source Root

image

在scala目錄下新建Test.scala,運(yùn)行進(jìn)行驗(yàn)證

image

二、通過(guò)maven plugin插件進(jìn)行開(kāi)發(fā)

1. 添加scala依賴(lài)

<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>

3. 添加scala源目錄進(jìn)行開(kāi)發(fā)

同 IDEA Scala插件開(kāi)發(fā)的1.3

如果項(xiàng)目需要多人進(jìn)行合作開(kāi)發(fā)的話(huà)，建議使用 maven plugin的方式進(jìn)行開(kāi)發(fā)
