我有 springboot 版本：2.5.6
Java 版本 17
我目前正在学习这门课程：https://deloittedevelopment.udemy.com/course/microservices-with-spring-boot-and-spring-cloud/learn/lecture/24346750#questions/16133790
在我的雇主提供的笔记本电脑上练习，可能与防火墙有关。 如果有人可以对此进行确认，或对解决方案提出建议。

作为一种解决方法，我使用 Dockerfile 手动创建了 docker 映像。
【问题讨论】：
Get "https://github-releases.githubusercontent.com/…": x509: certificate signed by unknown authority 建议您的 CA 证书可能已过期。您可以测试您的笔记本电脑是否可以使用以下openssl s_client -connect github-releases.githubusercontent.com:443 验证证书链。如果这样可行，那么问题可能出在 Java 密钥库中。
【参考方案1】：
要检查的一件事 BellSoft Liberica JRE 11.0.13：为层做贡献 从https://github.com/bell-sw/Liberica/releases/download/11.0.13+8/bellsoft-jre11.0.13+8-linux-amd64.tar.gz下载
在https://github.com/bell-sw/Liberica/releases/ 中查看以前的版本，看看它们是否可用，我没有看到你正在使用的那个。
对于证书，请检查： https://forums.docker.com/t/docker-private-registry-x509-certificate-signed-by-unknown-authority/21262/7
