vSphere Cloud: java.lang.NoSuchMethodError in SSHLauncher

Issue Type:	Bug
Assignee:	Unassigned
Components:	vsphere-cloud-plugin
Created:	2019-06-11 16:51
Environment:	vSphere Cloud 2.19, SSH Slaves 1.30.0
Priority:	Blocker
Reporter:	Nick Jones

Having upgraded to SSH Slaves 1.30, our vSphere Cloud plugin no longer works – agent nodes fail to provision, and a message like the following gets logged:

 
                                                                Unexpected exception encountered while provisioning agent agent1

Re: vSphere Cloud: java.lang.NoSuchMethodError in SSHLauncher

Looking at https://github.com/jenkinsci/vsphere-cloud-plugin/blob/6aee348fbe3a6c046383a2749de7b22c59152252/src/main/java/org/jenkinsci/plugins/vSphereCloudSlaveTemplate.java#L477-L481 and https://github.com/jenkinsci/ssh-slaves-plugin/blob/master/src/main/java/hudson/plugins/sshslaves/SSHLauncher.java#L249-L251, and when the signature of this SSHLauncher constructor was last changed, I'm not sure how this ever worked, as it looks to be missing an argument for the sshHostKeyVerificationStrategy parameter{{. Not sure what to do to fix?}}

Re: vSphere Cloud: java.lang.NoSuchMethodError in SSHLauncher

In our Jenkins installation even all statically configured SSH slaves are broken after the update to 1.3.0 of the SSH Slaves plugin. The plugin changelog has note about breaking changes, but gives no hint, how to get the SSH slaves working again. We had to restore version 1.29.4 from the backup (the plugin manager failed to that).
