How to mirror a p2 update site to my remote p2 update site?

Time:06-25

I have read this article about how to mirror a p2 update site to local, but how can I mirror a p2 update site (eg. https://download.eclipse.org/releases/2022-06 ) to one of my remote p2 update sites ?

By the way, are there any files required as a p2 update site? I noticed that the contents of the mirror-to local repository were missing some files, such as p2.index, compared to the mirror-from remote p2 update site.

CodePudding user response:

It does not matter whether your p2 update site is locally (accessed via file://...) or remotely (http://... or https://...). It's a folder structure that can be moved. So you can upload the directory of your to local mirrored p2 update site and vice versa.

A p2 repository must contain an artifacts.xml file and a content.xml file that might also be provided compressed as .jar and/or even more compressed as .xml.xz (assuming it's an artifact and a metadata repository in one and not separated, which is also possible). The p2.index file existing only for performance reasons. The best performance you will get with a p2.index plus an artifacts.xml.xz and a content.xml.xz file and for backward compatibility, an artifacts.jar file and a content.jar file in addition.

See Eclipse Wiki: What is the p2.index file? for more details.

You can also have a composite p2 repository.
