解决[ERROR] Plugin org.mybatis.generator:mybatis-generator-maven-plugin:1.3.7 or one of its dependenci

在使用maven管理项目时候，难免会出现一些找不到依赖的问题

入下面这种

如果出现上面的红色报错，此时还用maven 的clean 或者install操作

你会看到控制台出现以下信息

注意这句

点击它

 得到一个下载的文件

你仔细看控制台的提示信息发现

 [ERROR] Plugin org.mybatis.generator:mybatis-generator-maven-plugin:1.3.7 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.mybatis.generator:mybatis-generator-maven-plugin:jar:1.3.7: Could not transfer artifact org.mybatis.generator:mybatis-generator-maven-plugin:pom:1.3.7 from/to nexus-aliyun (https://maven.aliyun.com/repository/public): Connect to maven.aliyun.com:443 [maven.aliyun.com/127.0.1.2] failed: Connection refused: connect -> [Help 1]

他是说不能去xxx服务器下载这个玩意

那就手动下载下来

既然是maven需要下载下来的，肯定是下载到具体某个位置的

那么继续看看我们maven的pom中具体配置的是什么信息

没错了，就是这里  ，这里在你的maven仓库中可找到具体位置

 

 接着把手动下载下来的文件放进来，把.lastUpdated文件删除

再执行install一次看看

仓库位置中增加了几个新的文件

 

以上问题解决
