前言
在国内使用Maven下载远程仓库jar包,速度真是不太理想,慢的真心无法忍受。所以,最好的解决办法是通过Maven设置代理(使用XX-Net翻墙
)或者Maven使用代理。
Maven设置代理
- 编辑 ${user.home}/.m2/settings.xml 文件,如果该目录下没有该文件,复制 $MAVEN_HOME/conf/setting.xml
找到
<proxies>
节点,设置代理信息1

<id>xx-net</id>

<protocol>http</protocol>
<host>127.0.0.1</host>

</proxy>完成上述配置,仍然还是会有

[ERROR] Failed to execute goal on project xiaov: Could not resolve dependencies for project org.b3log:xiaov:war:2.2.0: Failed to collect dependencies at org.b3log:latke:jar:2.3.5 -> com.alibaba:druid:jar:1.0.16: Failed to read artifact descriptor for com.alibaba:druid:jar:1.0.16: Could not transfer artifact com.alibaba:druid:pom:1.0.16 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 -> [Help 1]
原因就是Maven走的是https,使用代理连接才会出现上述SSL认证问题。

请将下述配置信息覆盖settings.xml

Maven使用镜像
这里推荐使用阿里Maven仓库镜像(Nexus仓库),希望能稳定存活。
修改Maven的settings.xml文件,配置mirrors的子节点,添加如下mirror:1
