【问题描述】：

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：

在我重新启动 docker 服务之前，我遇到了另一个错误：

[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？

【问题讨论】：

你能解决我遇到类似问题的问题吗

@MohsinKhan 回答。

【参考方案1】：

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

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>
