命令行输入mvn -v可以成功,但输入mvn help报错:
No plugin found for prefix help in the current project and in the plugin groups
可能是配置文件出错了,找到C盘.m2文件夹下的setting.xml文件
修改mirror标签 如下:
<mirror>
<id>aliyunmaven</id>
<mirrorOf>*</mirrorOf>
<name>阿里云公共仓库</name>
<url>https://maven.aliyun.com/repository/public</url>
</mirror>
