In a Jenkinsfile, I'm trying to scp a zip file to a remote host, and ssh
some commands to unpack it when it gets there.
I managed to add a "SSH username with private key" credential, and I can
see it in the "Credentials" list. I'm referencing that uuid in my
"sshagent" block.
When I run the job, I see the following:
JP_MechIdPrivateKey[<myusername>-private-key] class[java.lang.String]
[ssh-agent] Using credentials <myusername>
[ssh-agent] Looking for ssh-agent implementation...
[ssh-agent] Java/JNR ssh-agent
[ssh-agent] Skipped registering BouncyCastle, not running on a remote agent
[ssh-agent] Started.
[Pipeline] {
[Pipeline] sh
[ssh-agent] Stopped.
[usl-parent] Running shell script
[Pipeline] }
[Pipeline] // sshagent
[Pipeline] }
[Pipeline] // dir
[Pipeline] sh

The code in question looks like this:
println "JP_MechIdPrivateKey[${JP_MechIdPrivateKey}]
class[${JP_MechIdPrivateKey.class.name}]"
sshagent (credentials: [JP_MechIdPrivateKey]) {
sh "scp ${javadocJarPath} ${JP_JavadocJarHost}:/tmp"
sh "ssh ${JP_JavadocJarHost} \"cd
${JP_JavadocRootRemotePath}; rm -rf ${versionNumber}; mkdir
${versionNumber}\""
sh "ssh ${JP_JavadocJarHost} \"cd
${JP_JavadocRootRemotePath}; jar xvf /tmp/${baseFileName}\""
}
I believe I've heard that in order to avoid serialization issues, I have to
put things in @NonCPS methods, but I don't understand what parts of this
would need to go into a @NonCPS method, and what CANNOT go into a @NonCPS
method.
