MVN 构建镜像 - “拨号 tcp：查找 github.com：名称解析暂时失败”

Question

我正在尝试使用命令构建 docker 映像mvn spring-boot:build-image -P<environment>，但出现错误：

在重新启动 docker 服务之前，我收到另一个错误：

[INFO]     [creator]     Get "https://repo.spring.io/release/org/springframework/cloud/spring-cloud-bindings/1.7.1/spring-cloud-bindings-1.7.1.jar": 
x509: certificate signed by unknown authority
[INFO]     [creator]     ERROR: failed to build: exit status 1

我缺少什么配置？

我在 Windows 上遇到类似的错误：

拨号tcp：查找objects.githubusercontent.com：i/o超时

将 DNS 更改为 1.1.1.1 解决了该问题。
