今天新建一个springboot项目时,项目建好后,在IDEA下载依赖包时,下载了很久都没有下载完,后来仔细一看,是下载不了。
解决方法:
在项目的pom.xml文件上右键,弹出框中选择maven,再选择open 'settings.xml' 或者是 create 'settings.xml' ,操作如图:
在该文件中填入如下内容:

<? 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" > < mirrors > < mirror > < id >nexus</ id > < name >internal nexus repository</ name > <!-- <url>http://192.168.1.100:8081/nexus/content/groups/public/</url>--> < url >http://repo.maven.apache.org/maven2</ url > < mirrorOf >central</ mirrorOf > </ mirror > </ mirrors > </ settings > |
重新右键pom.xml文件,选择 maven ,选择 Reimport 即可下载依赖。操作步骤及settings.xml文件内容如图:
settings.xml文件内容:
至此,依赖依法下载的问题已经解决。。
疑惑:将settings.xml文件中的<mirrors>替换成如下内容,竟然也无法下载依赖(但看网上博客说会让下载速度变快的)
