我有一个多模块maven项目，其中有4个模块。
一个 乙 C D（D取决于A，B，C）
所有这些模块都有共同的依赖关系，如spring-data-mongodb等。
当我进行全新安装时，我希望所有上述常见依赖项都捆绑到D中，但maven也将它捆绑到A，B，C中，并且D的jar文件大小很大。
有没有办法让maven将所有上述常见的依赖关系，例如spring-data-mongodb等放在一个地方，让所有的A，B，C和D都在jar中使用它？
谢谢。
父母pom如下：

PS：这是一个Spring启动项目。

您的依赖关系捆绑在每个工件中，因为您已在根POM的<dependencies/>中指定了它们。此列表应仅包含所有模块100％所需的依赖项。好的做法是首先使用根POM的<dependencyManagement/>部分中的版本定义每个项目依赖项，然后在每个模块POM的<dependencies/>部分中仅指定必要的依赖项。

问题在于我的Sprint启动插件配置（在父pom中添加），它将所有相关的jar捆绑到项目的所有模块中。
将构建弹簧引导插件移动到适当的模块后，maven将所有相关的jar放入一个地方，一切都很好。
