除了引用的包之外.我只设置了:

<build><plugins> <plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId> </plugin></plugins> </build>这是必须的.应该不影响

和 jdk版本配置

为什么每次都要去下载呢 ?

问题解答

mvn clean install test

可能两次依赖包的版本不一致，你可以去本地仓库看一下是否一个包下有多个版本。

首先要先确认idea里的maven和外部的maven用的是不是一个settings.xml
