本地仓库配置

本地仓库需首先在目标位置新建repository文件夹,执行mvn system:help命令从远程仓库下载相关包,可能需把默认位置repository文件夹复制过来.

  <localRepository>/usr/local/maven/repository</localRepository>
  <!--
  /home/kun/.m2/settings.xml #默认位置
  -->

mvn -v成功, mvn system:help报错

解决:没有相关jar包,maven配置文件导致,仓库位置问题,添加如下配置:

<mirror>
  <id>repo1 Maven</id>
  <name>all repository mirror</name>
  <mirrorOf>*</mirrorOf>	
  <url>https://repo1.maven.org/maven2</url>
</mirror>
