Try running mvn installon the Main project first.
首先尝试mvn install在 Main 项目上运行。
Your project is missing the other modules, which likely have never been installed to local repository.
您的项目缺少其他模块，这些模块可能从未安装到本地存储库中。
Not that you would have to run install every time before running jetty:run.
并不是每次运行之前都必须运行 install jetty:run。
An alternative would be to use the eclipse, right click MyProject -> Run as -> Maven build..., enter -Djetty:port=8081 jetty:runin the goals field and check "Resolve workspace artifacts".
另一种方法是使用 Eclipse，右键单击 MyProject -> Run as -> Maven build...，-Djetty:port=8081 jetty:run在目标字段中输入并选中“解决工作区工件”。
