当我尝试构建项目时出现以下错误:
无法在 org.msgpack:jackson-dataformat-msgpack:jar:0.8.17 -> com.fasterxml.jackson.core:jackson-databind:jar:2.9.9 处收集依赖项:无法读取 Artifact com.fasterxml.jackson.core的描述符:jackson-databind:jar:2.9.9:无法从/到maven传输 Artifact com.fasterxml.jackson.core:jackson-databind:pom:2.9.9(https://repo1.maven.org/maven2): sun.security.validator.ValidatorException: PKIX 路径构建失败: sun.security.provider.certpath.SunCertPathBuilderException: 无法找到请求目标的有效证书路径
我读到问题出在 http://repo1.maven.org/maven2 上我需要将其更改为https。搞定了，还是不行。然后我在google中找到了另一个建议->使用keytool添加maven证书并重新启动。做到了。还是不行。让一位同事向我发送他们的存储库，它起作用了(ofc，有所有依赖项)。然后我想在我们的junit测试中引入类别，所以我添加了surefire插件，这次问题是类似的:
Unable to generate classpath: org.apache.maven.artifact.resolver.ArtifactResolutionException:

所以我决定去一一下载，但这太糟糕了，我更喜欢解决这个问题而不是手动下载所有内容。
最佳答案
事实证明，问题出在我们的防火墙上 - 它以某种方式阻止了对所有 Maven 存储库的请求。当我要求 IT 停止并测试它时，maven 能够从标准 maven 存储库(带有 https 的存储库)下载所有内容
关于java - Maven 无法从 https ://repo. maven.apache.org/maven2 下载依赖项/插件，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/60300627/
