Download Atlassian SDK in 2025?

I am currently trying to download the atlassian-plugin-sdk-9.1.1.

The initial known URL was https://packages.atlassian.com/debian/atlassian-sdk-deb/.
It is now redirected to https://misc.artifacts.atlassian.com/ with a below return

AccessDenied
Access Denied

On markerplace side, from the page Atlassian Marketplace , the provided URL for “Download Installer” is https://marketplace.atlassian.com/download/apps/1210993/version/900100100

It requests now an authentification (not based on our Atlassian Partner Account) … Is it reserved to Atlassian team internally ?

In https://developer.atlassian.com/server/framework/atlassian-sdk/install-the-atlassian-sdk-on-a-linux-or-mac-system/#step-2--download-and-install-the-sdk , the provided URL is https://packages.atlassian.com/mvn/maven-external/com/atlassian/amps/atlassian-plugin-sdk/9.1.1/atlassian-plugin-sdk-9.1.1.tar.gz with also an authenficiation …

In https://developer.atlassian.com/server/framework/atlassian-sdk/atlassian-maven-repositories-2818705/, the below Maven Repositories are listed :
Atlassian Repository:

For 2 first URL, we have an authentication required.
For 2 last URL, we have the message
404, Sorry, the page you’re looking for cannot be found

… In Status Page, which service is related Maven Repoistories

Main question : How to retrieve the Atlassian SDK ?

UPDATE :
Related https://packages.atlassian.com/mvn/maven-external/com/atlassian/amps/atlassian-plugin-sdk/9.1.1/atlassian-plugin-sdk-9.1.1.tar.gz, by using another browser profile, the download works.

Hi @vthoule_smartview

You can retrieve the Atlassian SDK 9.1.1 juste here too: Atlassian Repository: com/atlassian/amps/atlassian-plugin-sdk/9.1.1/

We’re upgrading Atlassian SDK via Homebrew. It actually works pretty well.
