Symbolic link for "latest" for windows-stable in get.jenkins.io points to older release

[sofiatajos]

Problem with this page

https://get.jenkins.io/windows-stable/latest/

Expected behavior

https://get.jenkins.io/windows-stable/latest/ should point to latest LTS release.
As of writing this, LTS is 2.426.1.

Actual behavior

https://get.jenkins.io/windows-stable/latest/ points to version 2.222.1.

Possible solution

No response

@sofiatajos where did you encountered this https://get.jenkins.io/windows-stable/latest/ link?

Looking at the "Download" page of jenkins.io, I can only go to https://get.jenkins.io/windows-stable/ (which correctly serves the last LTS version 2.426.1), I haven't found any trace of "latest" link.

Hi @lemeurherve, we have been using the jenkins.io repository (https://get.jenkins.io/war-stable/latest/jenkins.war) for an automatic build in order to always pull the latest WAR file, and wanted to do the same for the MSI installer.

To pull the latest Jenkins.msi installer, currently we can use https://get.jenkins.io/windows-stable/2.426.1/jenkins.msi. This can be seen from this link (https://www.jenkins.io/download/thank-you-downloading-windows-installer-stable/) after manually clicking on Windows from the Jenkins Download page.

I was thinking that expected behavior for latest for the MSI installer would be the same as the WAR file links, and found that https://get.jenkins.io/windows-stable/latest/ leads me to https://get.jenkins.io/windows-stable/jenkins-2.222.1.zip/.

With this https://get.jenkins.io/windows-stable/latest/jenkins.msi actually downloads version 2.222.1 of the msi installer.

Thanks!

Thanks @sofiatajos for these explanations.

This issue is the same as #3034.

It might be resolved by #3414. Putting this last help desk issue on our next infra milestone.

Meanwhile, I can propose you to construct your own "latest" download link by retrieving the last LTS version from https://updates.jenkins.io/stable/latestCore.txt

Hi @lemeurherve, I understand. We've already implemented your suggestion to get the link for the latest LTS version, but I just wanted to report this so it wouldn't be missed. Thanks!

Update: as per jenkinsci/gradle-plugin#387, the proper way to get the latest WAR is to use the updates.jenkins.io webservice (which hosts the update center index but also provide custom logic to emit redirects to the latest version:

https://updates.jenkins.io/current/latest/jenkins.war redirects to https://updates.jenkins.io/download/war/2.440/jenkins.war (today: next week the version will be updated)

It does NOT work for other packages (MSI, deb, rpm, etc.) though.
