当我将 JRE 版本从 1.8 更改为 1.6 时，Maven-jetty-plugin 无法解决项目依赖关系
Maven-jetty-plugin can't resolve project dependency when I changed JRE version from 1.8 to 1.6
OS: openSUSE Leap 4.2
IDE：日食火星
JDK 已安装：打开 JDK 1.8 & Oracle JDK 1.6
我最近必须向现有系统添加一些新功能。我的环境如上
这个系统有 5 个独立的项目，它们的根文件夹设置并排，并使用 maven 来管理构建周期。
部署环境的 JRE 版本是 Oracle JDK1.6，所以在实施新功能并使用 JDK1.8 成功测试后，我必须在我的开发环境中将其降级，虽然我认为这五个项目的文件夹结构并没有按照maven的推荐来排列。
当我将 Installed JDK 从 1.8 更改为 1.6 时，尝试使用 maven-jetty-plugin(jetty:运行) 运行 系统，我得到以下错误输出:

为什么JDK1.6无法正确识别yingfan-cpm-web项目对yingfan-cpm-core项目的依赖？
P.S。 JDK版本是这两种情况的唯一区别。
