An adapter of Jenkins update center.
Why
Jenkins downloads the plugins by parsing the JSON file which comes from a update center. One thing that you might already noticed is about the speed of downloading. Accessing a global storage for everyone could be slow although there're many mirror sites.
If you deep into the file update-center.json.
Almost every mirror file is base on http://updates.jenkins-ci.org/download/plugins.
So, the result is that these mirror sites can only speed up the process of downloading file update-center.json.
Jenkins can download the .hpi from your target mirror site.
Background
It's might not be a good idea to change the update-center.json file directly. keeping sync all files
should be simple without other logic.
Second, you need to provide a certificate file if you changed the update-center.json. Because Jenkins
will validate the file before parsing it. It's necessary due to the safety reason.
Design
- Create an adapter to replace the base URL
- Provide a certificate file
How to
Here's a prototype implement which added into localization-zh-cn-plugin. You Just need to take three steps if you want to use a real mirror of update center:
- install localization-zh-cn-plugin 1.0.10
- use the new certificate file
- change the update center URL
