Jenkins plugin conflict resolution and version upgrade

First come an error message, which is really hard to pull. .

1. First solve the first problem, change the plug-in download address to a domestic source

Official source: https://updates.jenkins.io/update-center.json
Domestic source: https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/current/update-center.json
Domestic source 2: http://mirror.xmission.com/jenkins/updates/update-center.json

Modify the configuration file

Enter /updates/default.json in the jenkins installation directory, and replace updates.jenkins-ci.org/download with mirrors.tuna.tsinghua.edu.cn/jenkins,
In some jenkins versions, updates.jenkins.io/download is replaced by mirrors.tuna.tsinghua.edu.cn/jenkins
Then, change www.google.com to www.baidu.com

sed -i 's#http://updates.jenkins-ci.org/download#https://mirrors.tuna.tsinghua.edu.cn/jenkins#g' default.json
sed -i 's#http://www.google.com#https://www.baidu.com#g' default.json

restart jenkins

2. In the process of solving the plug-in installation problem, I found that my jenkins version was too low, resulting in incompatibility of some installed plug-ins or plug-ins that the installed plug-ins depend on, so the second problem is to upgrade jenkins

Here I installed jenkins with docker. You can read my previous article for installation, so you must first enter the jenkins container

3. After replacing the jenkins.war file, the docker image file cannot start the solution

  778  docker cp 456f:/usr/share/jenkins/jenkins.war ./
  779  ll
  780  docker cp 456f:/usr/share/jenkins/jenkins.war.2.328.bak ./

Screenshot after repairing the problem
Note: Due to the replacement of the war file, both the ssh credentials and the java-web file need to be replaced, just restart after replacement
