Remember a jenkins build failure

Today, I have been stuck on downloading a jar package during the build. With the help of the development partners, I found a solution:

Modify the maven configuration file (/usr/local/apache-maven/conf/settings.xml) and add the following in the <mirrors></mirrors> tags:

<mirror>
  <id>alimaven</id>
  <name>aliyun maven</name>
  <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
  <mirrorOf>central</mirrorOf>
</mirror>

Then rebuild it again.

The reason for this failure may be that maven uses foreign mirrors by default, and there is a problem of network delay or interception. It is good to change to domestic mirrors.
