Eclipse Maven 构建Java和Scala混合项目

一，Eclipse 安装Maven 插件

可以到Eclipse Maket去搜索

二，安装scala插件

     1，新的scala插件可以在Eclipse Maket搜索安装；

     2，要想安装旧的，比如scala2.10.4插件，就要下载，Eclipse scala离线安装插件：Help->Install New SoftWare->add->local,选择本地插件地址

三、配置Ecipse Maven插件的远程Archetype库：windows->preference->Maven->Archetype->add
Remote Catalog,在catalog file输入：http://repo1.maven.org/maven2/archetype-catalog.xml，这是maven中央仓库的archetype-catalog地址：

四、new->maven->maven project->选择刚刚新建的catalog，然后搜索scala,选择scala-archetype-simple

五、修改新建Maven项目的pom文件。添加scala-maven-plugin

例如：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

六、自己新建src/main/java等source folder,结构如下
