java - 包 redis.embedded 不存在

标签 java spring intellij-idea spring-boot redis

我使用一个小型 Spring Boot 项目，在使用命令 mvn clean install 时出现以下错误

很明显，我在项目中使用了embedded-redis依赖，

        <dependency>

这是我收到错误消息的文件，

如何解决问题？

最佳答案

您为依赖项设置的范围是测试。因此在使用 clean install 时不包含它。删除范围标记并重试。

有关 Maven 依赖范围的更多信息: https://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html#Dependency_Scope
