Suspend distribution of Crowd2 plugin

Suspend distribution of Crowd2 plugin

jenkins-infra/helpdesk#3854 explains that the Crowd2 integration plugin uses a dependency that is not open source licensed.

The Crowd2 integration library is Atlassian licensed as described in jenkins-infra/helpdesk#3842 (comment)

The Atlassian license is not an open source license. Refer to https://www.atlassian.com/legal/software-license-agreement for the details of the license.

https://www.jenkins.io/project/governance/#license says that the Jenkins project requires plugins that it distributes to be open source, including their dependencies. When a closed source dependency is detected in a plugin, we suspend distribution of that plugin. If maintainers update the plugin to remove the closed source dependency, distribution can begin for the new release that removes the closed source dependency.

Fixes jenkins-infra/helpdesk#3854

Could we ping the maintainers before suspending, so it at least doesn't catch them by surprise?

The only active maintainer left is @DuMaM, FYI above.

That's a great suggestion. I sent a message to the email address (as stored on accounts.jenknis.io) of the 5 maintainers. My guesses of the GitHub identities of those maintainers are:

• @KostyaSha
• @martinspielmann
• @DuMaM
• @akouznetchik

Hi Everyone,

I will be unable to rewrite this and make it open source, but I've just bumped into this notice:
https://www.atlassian.com/licensing/crowd#crowd-data-center

Important changes to our Server and Data Center products
We’ve ended sales for new server licenses and will end support for server on February 15, 2024 PT. We’re continuing investment in Data Center with several key improvements. [Learn what this means for you.](https://www.atlassian.com/migration/assess/journey-to-cloud)

And, because of that, think it will be better to suspend this plugin.

Could you please prepare, notification info for users about this change?

Thanks

Hi,

I archived a plugin and labeled this as deprecated.
Could you please add notice here?

Thanks for adding the deprecated topic to the repository and archiving that repository. That makes it very clear that it is deprecated and not receiving further changes.

The update center instructions say:

Use this file to mark a plugin as deprecated while continuing to distribute it. If a plugin should be removed from distribution entirely, instead set a deprecation notice URL in artifact-ignores.properties.

The addition to artifact-ignores.properties is what has been done in this pull request.
