settings.xml中程式碼已文章下給出
當你在settings.xml指定了本地倉庫,當你的專案需要jar包的時候,maven會去本地倉庫中查詢,如果沒有會去國內maven倉庫下載到你制定的本地倉庫.

settings.xml

需要修改的是你的倉庫的位置

<?xml version="1.0" encoding="UTF-8"?>

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 

          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
