Question

我正在使用Scala代码进行Maven项目，我想基于不同的Scala版本（2.10.6和2.11.8）生成两个jar。如果有人请建议解决方案我如何在单个maven安装执行中实现这一点，或者如果在Maven中使用某些Maven插件有任何其他方法来实现这一点。

Answer 1

创建针对不同版本的Scala重写依赖关系的配置文件。您需要在两个配置文件上运行mvn install。有关详细信息，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。

我能够使用多次执行来解决这个问题。
