maven混合编译java&scala

步骤：

1. mvn 生成scala项目
mvn archetype:generate \

-DarchetypeGroupId=org.scala-tools.archetypes \

-DarchetypeArtifactId=scala-archetype-simple \

-DremoteRepositories=http://scala-tools.org/repo-releases
或 参考 笔记《Idea+Maven创建scala项目》

2.添加java目录，添加完后，在IDEA中目录结构如下：



3.修改pom.xml文件
删除：



在<build><plugins>下增加maven插件：
<plugin>

<groupId>org.codehaus.mojo
</groupId>

<artifactId>build-helper-maven-plugin
</artifactId>

<version>1.9.1
</version>

</plugin>

4.直接使用package打包，打包结果如下图：



5.pom.xml文件示例：
