被 maven-dependency-plugin 视为未使用的 Spring Boot 核心依赖项 [英] Spring boot core dependencies seen as unused by maven-dependency-plugin

问题描述

maven-dependency-plugin 将 Spring Boot 依赖项检测为未使用，但实际上需要它们来运行我的应用程序.我会做错什么吗?

maven-dependency-plugin detects spring boot dependencies as unused, but they are actually requied to run my application. Would I have made something wrong ?

推荐答案

这是正常的，因为您的代码不直接使用任何这些依赖项.Spring Boot 的工作方式是分析您的类路径，并通过添加相应的依赖项为您自动配置许多不同的东西.由于配置发生在您的应用程序代码之外，Maven 认为这些依赖项是未使用的.

This is normal since your code doesn't directly utilize any of those dependencies. The way Spring Boot works is it analyzes your classpath and will autoconfigure many different things for you simply by adding the corresponding dependency. Since the configuration is happening outside of your application code, Maven believes these dependencies to be unused.
