Jenkins how to use jenkins variables in sshCommand plug-in? - jenkins

Question

I'm building war file by using maven and sending this build to another server via Jenkins ssh Publisher plugin.
stage('Deploy develop build to Test Server') {
when {
branch 'develop'
}
steps {
// sends war file to test_server
dir("${WORKSPACE}/ag.mycompany.feature/target/") {
sshPublisher(
alwaysPublishFromMaster: true,
continueOnError: false,
failOnError: true,
publishers: [
sshPublisherDesc(
configName: "test_server",
transfers: [sshTransfer(sourceFiles: "vc-admin_${VERSION}_${BUILD_NUMBER}_dev.war", remoteDirectory: '/wars/main_vc_admin/develop')],
verbose: true
)
]
)
}
}
}
this part working very well, I can see my war file with version and build number
then, I'm trying to cp these files (in remote server) to another folder and build a docker image via docker-compose.
connection to remote server via withCredentials is OK, and I tested with some sudo command like 'docker ps' and working well.
but I can't pass variables like VERSION and BUILD_NUMBER to sshCommand
is there any way to pass these variables?
And all examples in internet that I saw are in script{ ... } block for withCredentials and sshPublisher, that's why I used script block in declerative pipeline. I don't know how to create remote variable by using declerative pipeline.
stage("build docker containers") {
when {
branch 'develop'
}
steps {
script{
withCredentials([sshUserPrivateKey(credentialsId: 'test_server',
keyFileVariable: 'test_user',
passphraseVariable: '',
usernameVariable: 'test_user')]) {
// code block
def remote = [ : ]
remote.name = "MY_TEST_SERVER"
remote.host = "1.1.1.1"
remote.user = "user"
remote.password = "pass"
remote.allowAnyHosts = true
remote.identityFile = test_user
remote.pty = true
sshCommand remote: remote, command="cp /home/user/wars/main_vc_admin/develop/vc-admin_${VERSION}_${BUILD_NUMBER}_dev.war /home/user/main-vc-deployment/backend/vc-admin.war"
sshCommand remote: remote, sudo: true, command: "docker-compose --file /home/user/main-vc-deployment build && docker-compose --file /home/user/main-vc-deployment run -d"
}
}
}
}
