Question

我目前有一个平面结构的项目，具有以下依赖性;

    Core  --> core.jar
            Service --> WAR
            Domain --> domain.jar
                    Web  -> WAR

差不多，一切都取决于Core模块的core.jar，而Web依赖于Domain模块的域jar，这取决于Core。

我打算将其转换为Maven，我需要一些反馈我应该使用的最佳结构。

我的选择是保持当前结构，然后从每个模块生成jar文件，并将它们用作maven依赖的一部分。要么在某种层次结构中重新构建模块，我需要一些帮助。

我想遵循Maven的某种最佳实践。

Answer 1

设置父pom，您可以使用它来保持子项目中的依赖关系。然后将每个jar / war工件设置为模块。

每个模块使用模块pom中的普通<dependencies>来获取其依赖关系。

所以有这个：

parent-project [pom]: 
    modules: 
       core [jar]
       domain [jar] - depends on core
       service [war] - depends on core
       web [war] - depends on domain

作为一个具体的例子，这是我的一个项目的样本：

Answer 2

我认为我试图展示的内容符合您的选择。

创建POM项目为父
将每个jar和war添加为模块

我的选择是保持当前结构，然后从每个模块生成jar文件，并将它们用作maven依赖的一部分。

Maven项目设置
