重复获得 "PKIX path building failed" 和 "unable to find valid certification path to requested target"

Question

我在 mvn clean install 执行期间一直面临证书这个烦人的问题。

我发现 solution 工作正常。

现在的工作方式是我必须通过浏览器访问（即 https://repo.spring.io/milestone or https://repo.maven.apache.org/maven2/）错误提及的网站，然后必须从那里导出证书（如下图所示）并加载到 lib\security\cacert 每次我遇到这个`PKIX 构建错误时都使用 keytool。
有时我必须再次访问同一个站点https://repo.maven.apache.org/maven2/并且需要重新下载证书并插入lib\security\cacert 使用 keytool，如 solution 中所述。

有什么办法可以一劳永逸地解决这个问题吗？

系统:

Apache Maven 3.8.4 
Maven home: C:\apache-maven-3.8.4
Java version: 17.0.1, vendor: Eclipse Adoptium, runtime: C:\Program Files\Eclipse Adoptium\jdk-17.0.1.12-hotspot
Default locale: en_IN, platform encoding: Cp1252
OS name: "windows 10", version: "10.0", arch: "amd64", family: "windows"

Answer 1

我可以通过替换 cacert 文件来解决这个问题。更准确地说，我已将 Eclipse Adoptium\jdk-17.0.1.12-hotspot 的 cacert 替换为 Eclipse Adoptium\jre-8.0.312.7-hotspot 来修复它。

令我惊讶的是，替换新的 cacaert 文件后，我不必使用 keytool 手动加载证书。旧的 cacert 文件导致问题的原因仍然是个谜。

注意：在替换新文件之前备份原始 cacert 文件。

如果仍未解决，请尝试此 solution。
