Proposal: Excluding JRebel support from the Jenkins core (JENKINS-64037)

[Oleg Nenashev]

Hi all,

At some point there was a JRebel model added to Stapler and the Jenkins core. It was used to support hot reloading of classes when developing Jenkins in some conditions: https://wiki.jenkins.io/display/JENKINS/Developing+with+JRebel .

This flow has not been used for a long time. It is unlikely that it can operate properly anymore, especially with Java 11. I suggest removing the dependency on JRebel to reduce the Jenkins core size and to prevent potential transitive dependency issues and to slightly reduce the jenkins core's footprint. What do you think?

P.S: If someone wants to recover the JRebel support and demonstrate it, it might be even better than just removing the component.

Thanks in advance,

Oleg

That seems reasonable to me.

Makes sense. If and when somebody wants to use this, they can figure
out how to freshen it up.

Same question about https://github.com/stapler/stapler-adjunct-zeroclipboard . It is a part of the Jenkins core API and it "provides an easy way to copy text to the clipboard using an invisible Adobe Flash movie and a JavaScript interface". Yes, with flash...  Last release of this Stapler module was in 2014, last release of the upstream https://github.com/zeroclipboard/zeroclipboard was in 2017. 

I was unable to find any real usages of https://github.com/stapler/stapler-adjunct-zeroclipboard/blob/master/src/main/resources/org/kohsuke/stapler/zeroclipboard.jelly in the Jenkins core and plugins

With Adobe Flash being deprecated and EoLed, maybe we should also remove this library from the core

FTR https://github.com/jenkinsci/jenkins/pull/3780 is why
