这个错误是Gradle构建工具在解决依赖关系时出现的问题。它表示Gradle无法找到符合您项目要求的Spring Boot Gradle插件的版本。根据错误消息，您的项目需要Java 8兼容的版本，但是Gradle解析的版本似乎只兼容Java 17。您可以尝试更新Gradle和Spring Boot Gradle插件的版本，或者尝试明确指定使用Java 8兼容的版本。您可以尝试在build.gradle文件中添加以下内容来明确指定使用Java 8兼容的版本：

plugins {
    id 'org.springframework.boot' version '2.5.4'
}

请注意，版本号可能需要根据您需要使用的版本进行更改。
