Question

我正在具有3级结构的Maven环境中工作：

Maven项目POM结构
  公司POM
  --项目POM
  ----模块1 POM
  ----模块... POM

公司POM定义了dependencyManagment和pluginManagement。这些默认值在公司级别维护。在项目POM中，我想覆盖项目POM中的某些默认值，并将其用于我的所有模块。

问题： 是否可以通过公司POM利用项目POM中的dependencyManagement和pluginManagement设置？

如果我需要详细说明问题或提供更多信息，请相应地指导我！

“项目POM”->是指公司POM。

Answer 1

问题：是否可以通过公司POM利用项目POM中的dependencyManagement和pluginManagement设置？

您可以这样做吗？是的，可以同时指定依赖项/插件管理以及实际的/来覆盖父设置。

您应该这样做吗？否，这使得POM管理的方法非常“不干净”，并且违背了最初使用dependencyManagement和pluginManagement的逻辑。

覆盖多个级别的POM中的依赖项/插件管理
