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

mvn spring-boot:build-image -P<environment>

命令构建 docker 映像，但出现错误：

[INFO]     [creator]     ERROR: failed to build: exit status 1

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？

Answer 1

我遇到了类似的错误：

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

我通过在 Docker Windows 桌面中禁用 beta 功能（尤其是

containerd

）解决了这个问题。

Answer 2

使用 spring-boot 2.4.2 和 Java 11 版本修复了该问题：

pom.xml

<parent>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-parent</artifactId>
  <version>2.4.2</version>
  <relativePath/>
</parent>

<properties>
  <java.version>11</java.version>
  <maven.compiler.source>11</maven.compiler.source>
  <maven.compiler.target>11</maven.compiler.target>
  <spring-cloud.version>2020.0.1</spring-cloud.version>
</properties>
