</project>

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 ?

Answer 1

mvn 全新安装测试

Answer 2

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。

Answer 3

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