1. 新建專案

File->new project
選擇maven專案，勾上Create from archetype，選擇
scala-archetype-simple

標記路徑為Source root：在目錄上右鍵 -> “Mark directory as”

兩個Source root

• src/main/java
• src/main/scala

兩個test source root

• src/test/java
• src/test/scala

2. pom配置

        <project.build.sourceEncoding
 
>UTF-8</project.build.sourceEncoding>
        <hadoop.version>2.7.3</hadoop.version>
        <compile.version>1.8</compile.version>
        <junit.version>4.12</junit.version>
    </properties>

3. 打包命令

mvn clean scala:compile compile package

4. 檢視jar包內容

jar vtf xxx.jar
