你期待的结果是什么？实际看到的错误信息又是什么？

<parent>那一行报错 报错信息这里报错，报错
Multiple annotations found at this line:- For artifact {org.springframework.boot:spring-boot-starter-redis:null:jar}: The version cannot be empty 后面还有一大串什么

<denpendcy>也报错 Project build error: 'dependencies.dependency.version' for org.springframework.boot:spring-boot-starter-redis:jar is missing.

报错的两个地方我标注出来了 这是直接导的github上的一个例子 不知道为什么导入进去报错了

Answer 1

一般来说, spring-boot 的 parent 应该是这个

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.0.RELEASE</version>
        <relativePath /> <!-- lookup parent from repository -->
    </parent>

Answer 2

spring-boot-starter-redis配置下方添加版本号
