[WARNING] Could not transfer metadata org.sonarsource.sonar-packaging-maven-plugin:sonar-packaging-maven-plugin/maven-metadata.xml from/to central (https://repo.maven.apache.org/maven2): sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
使用技术：maven 仓库：阿里云
如果报上边那个错误，有多种情况，最直接的方法就是换仓库，可以换国内的或国外的，
国内的下载快，但第三方可能存在验证问题；国外的下载较慢，其实也不是很慢，推荐国外使用maven官方的。
首先说一下我最后的解决方法。
我的方法一：
打开idea---》setting---》runnner
在vm options中添加：-Dmaven.wagon.http.ssl.insecure=true -Dmaven.wagon.http.ssl.allowall=true 中间用空格隔开
根据网上搜查，大致还有以下几个方案，不过我尝试都没效果
1.删除本地仓库依赖（我删除了本地仓库，没有效果，反而使项目依赖全都没有，一堆爆红）
2.判斷是连到 repo.maven.apache.org 的时候凭证未信任.

打包
$ javac InstallCert.java
執行
$ java InstallCert repo.maven.apache.org
他會問你
Enter certificate to add to trusted keystore or ‘q‘ to quit: [1]
輸入 1 ,之後會在執行目錄下生成 jssecacerts
將“jssecacerts”的文件放入JAVA_HOME/jre/lib/security目錄下
再進行maven編譯就可以了
