While your build may be running on Java 17, it has been configured to require Java 8. This is shown in Gradle's error message above:
The consumer was configured to find a runtime of a library compatible with Java 8
Perhaps you have misconfigured sourceCompatibility in your Gradle script? Setting to 1.8 will produce the error you are seeing. It should be set to 17 as shown in a project generated on https://start.spring.io.
If you have any further questions, please follow up on Stack Overflow or Gitter. As mentioned in the guidelines for contributing, we prefer to use GitHub issues only for bugs and enhancements.

虽然您的构建可能在 Java 17 上运行，但它已被配置为需要 Java 8。这在 Gradle 上面的错误消息中显示：
The consumer was configured to find a runtime of a library compatible with Java 8也许您
sourceCompatibility在 Gradle 脚本中配置错误？设置为1.8将产生您所看到的错误。它应该设置为在https://start.spring.io17上生成的项目中所示。如果您还有其他问题，请关注 Stack Overflow 或Gitter。正如贡献指南中提到的，我们更喜欢仅将 GitHub 问题用于错误和增强功能。
i did configure sourceCompatibility 17,and i did downloaded from start.spring.io;2.6.3 is ok
id 'org.springframework.boot' version '2.6.3'
this is my configuration:
plugins {

id 'io.spring.dependency-management' version '1.0.11.RELEASE'
id 'java'
}
group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '17'
configurations {

Could you share the output of ./gradlew --version as well as the content of the settings.gradle file? A complete, sample project that we could check out on GitHub would also help.
Comment From: snicoll
Also make sure that ./gradlew --version shows that you're using Java 17.

i found something showed up on my idea
Comment From: wilkinsona
Thanks for the sample. It works for me with both Oracle JDK 17 and OpenJDK 17. This is the first time that you've mentioned IDEA. It may be that you need to upgrade so that your IDE is aware of JDK 17. See https://youtrack.jetbrains.com/issue/IDEA-282531 and the issues to which it links. This is all out of Spring Boot's control so I'm afraid there's nothing more that we can do to help you here.

@wang-xiaowu we've already indicated that all of this is out of Spring Boot's control so there's not much we can do to help you here.
