## 问题 ##

当 Maven 升级到3.8.1 之后，执行 mvn clean package 命令后会报错如下：

maven-default-http-blocker (http://0.0.0.0/): Blocked mirror for repositories

## 分析 ##

maven在3.8.1 的默认配置文件中增加了一组标签，如果仓库镜像是http 而不是https 就会被拦截禁止访问,而当前公司私服一般是http 而不支持https.

## 解决思路 ##

### 思路一: 降低Maven 版本到3.8.1 以下 ###

### 思路二：增加节点 ###

示例如下：

<mirror>
      <id>insecure-repo</id>
      <mirrorOf>external:http:*</mirrorOf>
      <url>http://www.ebi.ac.uk/intact/maven/nexus/content/repositories/ebi-repo/</url>
      <blocked>false</blocked>
    </mirror>

### 思路三：将镜像仓库从http 变成https ###

### 思路四：注释掉 $MAVEN\_HOME/conf/settings.xml 中的拦截标签 ###

## 解决方案 ##

*  找到Maven安装目录
 *  编辑 $M2\_HOME/conf/settings.xml
 *  注释如下代码

<mirror>
     <id>maven-default-http-blocker</id>
     <mirrorOf>external:http:*</mirrorOf>
     <name>Pseudo repository to mirror external repositories initially using HTTP.</name>
     <url>http://0.0.0.0/</url>
     <blocked>true</blocked>
     </mirror>
