maven - 在子 java 模块 pom 中声明依赖项的必要性

Question

当父级的 pom at (or ) 部分中存在依赖项时，是否有必要在子级的 pom.xml 中声明依赖项？他们是遗传的吗？

Answer 1

The fallowing elements from the parent POM are inherited by the children pom's:

• Dependencies
• Plugin executions
• Plugin configurations
• Other misc. elements (e.g SCM settings, developers, reports)

For more info see: Pom Inheritance

So in your case you don't need to declare again the dependencies in the child pom.
