Latest plugin for ssh-agent I'm getting all these com.cloudbees.jenkins.plugins.sshagent.LauncherProvider missing errors.

Has it been replaced or accidently deleted or something happen?

Can someone confirm that this class has in fact been permanently removed and if so what it's replaced with?

https://github.com/jenkinsci/ssh-agent-plugin/tree/master/src/main/java/com/cloudbees/jenkins/plugins/sshagent  you'll notice LauncherProvider.java is now gone.   Removal was part of this commit, https://github.com/jenkinsci/ssh-agent-plugin/commit/c84ce1c5751ec6d4048e2254819c46719147855b 

Documentation still has it listed even though it's removed in source 

https://javadoc.jenkins.io/plugin/ssh-agent/com/cloudbees/jenkins/plugins/sshagent/LauncherProvider.html

If I run this on the latest .jpi I get nothing

unzip -l ssh-agent/WEB-INF/lib/ssh-agent.jar | grep LauncherProvider

previous version...

$ unzip -l WEB-INF/lib/ssh-agent.jar | grep LauncherProvider

As for other plugins... There was one other I saw come up (probably where I got the code to use the LauncherProvider class) but can't find it at the moment.
