You should consider using a dependency management/build tool such as Maven or Gradle . 您应该考虑使用诸如Maven或Gradle之类的依赖项管理/构建工具。

This way each of your projects will be a module, which can be referenced from the other project as a dependency. 这样，您的每个项目都将是一个模块，可以从另一个项目中将其作为依赖项进行引用。 You can still use the first project alone and the two-dependent projects alone as wall. 您仍然可以单独使用第一个项目，也可以单独使用两个依赖项目。 Then the tool lets you just simply package the resulting project in a artifact such as WAR with all the dependencies. 然后，该工具使您可以简单地将生成的项目打包到带有所有依赖项的工件（例如WAR）中。

It is a good idea to use such a tool in any case as it has many additional advantages: 在任何情况下都使用这种工具是一个好主意，因为它具有许多其他优点：

Lets you manage also your third party dependencies without needing to manually download the libraries and add them to the classpath 使您还可以管理第三方依赖性，而无需手动下载库并将其添加到类路径
It is much easier to use such a project in cases like continuous integration. 在诸如持续集成的情况下使用这样的项目要容易得多。
You can run all your tests automatically during the build process to make sure everything works 您可以在构建过程中自动运行所有测试，以确保一切正常
It resolves transitive dependencies (dependencies of your dependencies) 它解决传递依赖（依赖关系的依赖关系）
It builds resulting archive file for you 它为您构建生成的存档文件
You can have multiple profiles for different environments 您可以针对不同的环境使用多个配置文件

Make both of your projects modules of one Maven parent pom project. 制作一个Maven父pom项目的两个项目模块。 This way you can build them both at the same time. 这样，您可以同时构建它们两者。
