今天在B站视频找了BV1GK4y1v7xz尚硅谷的springcloud视频，出现一点问题。

父组件pom

子组件的pom里面的maven依赖报错找不到原因下载的依赖全是 unknown，找了一下午才发现父组件pom里面的

<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-dependencies</artifactId> <version>2.2.2.RELEASE</version>

<scope>import</scope> </dependency>

<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>Hoxton.SR1</version>

<scope>import</scope> </dependency>

<dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-alibaba-dependencies</artifactId> <version>2.1.0.RELEASE</version>

<scope>import</scope>

里面的<type>pom</type>把pom写成了大写字母，记录一下
