使用不同的Scala版本生成两个相同的Maven项目的瓶子

Question

我有一个使用Scala代码的Maven项目，我想根据不同的Scala版本（2.10.6和2.11.8）生成两个jar。 如果有人请建议的解决方案，我如何才能做到这一点单Maven的安装执行或是否有使用一些Maven插件Maven中实现这一目标的任何其他方式。

Answer 1

我能够使用多次执行来解决此问题。

<build> 
    <plugins> 
    <plugin> 
     <groupId>net.alchim31.maven</groupId> 
     <artifactId>scala-maven-plugin</artifactId>

       <configuration>

       <outputDir>${project.build.outputDirectory}/scala-2.10</outputDir>

创建具有依赖性覆盖了不同版本的Scala的概况。您需要在两个配置文件上运行mvn install。欲了解更多信息，请参阅：different-dependencies-for-different-build-profiles-in-maven

此外，您还需要更改配置文件中的工件名称/版本以区分这两者。
