Maven使用阿里云镜像的问题 最近这几天创建新项目的时候,maven总是会下不了jar包,并且idea日志中会有如下错误

PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilder把你的maven的setting.xml中阿里云地址从http改为https即可 同时 如图位置可以同时改为
-Didea.maven3.use.compat.resolver -Dmaven.wagon.http.ssl.insecure=true -Dmaven.wagon.http.ssl.allowall=true前面为了防止maven报错,后面是取消ssl校验
—————————————————2020/7/6更新—————————————————————— 突然发现还是会报这个错，于是尝试了一下网上的安装证书方法，但是没有什么用 安装证书过程中也遇到一个问题，c盘的jdk我们没有权限加证书，于是将jdk装到D盘，但是D盘你使用keytool工具装证书的时候说'keytool' 不是内部或外部命令,也不是可运行的程序 解决方案：在你jdk的lib包下面打开cmd输入keytool -v -list -keystore，解决该问题 最终解决方案 点击输入 mvn clean install -Dmaven.wagon.http.ssl.insecure=true -Dmaven.wagon.http.ssl.allowall=true 解决该问题
