maven依赖整理

转发请会注明出处：

　　最近发现项目打的包都比较大，无论在本地部署还是在环境上部署，都比较影响效率。所以整理一下项目中得依赖，去除没有引用得一些依赖。

　　主要用到两个命令：

1. 查看依赖树

mvn dependency:tree

　　这将显示当前项目的完整依赖结构，帮助你了解哪些依赖被引入及其版本。

2.分析未使用依赖

mvn dependency:analyze

　　此命令会报告：

• Used undeclared dependencies - 使用了但未显式声明的依赖　　　　
• Unused declared dependencies - 声明了但未使用的依赖

3.整理

• 运行 mvn dependency:analyze 来获取初步的依赖使用分析报告
• 对报告中标记为"Unused declared dependencies"的依赖进行人工核查
