How to put value in variable in Jenkinsfile with sshcommand - jenkins

Question

I would like to create a Pipeline in Jenkins which get the value of a command executed with sshCommand.
I've got a file like this on a remote server :
VALUE 11
Here is my Pipeline :
pipeline {
agent any
stages {
stage('Get Init') {
steps {
withCredentials([[$class: 'UsernamePasswordMultiBinding', credentialsId:'xxxxxxx', usernameVariable: 'USERNAME', passwordVariable: 'PASSWORD']]) {
script {
def remote = [:]
remote.name = 'xxxxxx'
remote.host = 'xxxxxx'
remote.user = USERNAME
remote.port = 22
remote.password = PASSWORD
remote.allowAnyHosts = true
sshCommand remote: remote, command: "init=\$(cat /var/log/myFile | grep VALUE | awk '{print \$2}')"
}
}
}
}
stage("Test") {
steps {
script {
test = sh(script "echo $init")
}
}
}
}
}
}
I want to get the "11" in a variable to compare it later in my Jenkinsfile. How to do this ?

Answer 1

You can use in below way :
Example:
def Result = sshCommand remote: remote, command: "<Your command>"
# Declare variable init
def init
pipeline {
agent any
stages {
stage('Get Init') {
steps {
withCredentials([[$class: 'UsernamePasswordMultiBinding', credentialsId:'xxxxxxx', usernameVariable: 'USERNAME', passwordVariable: 'PASSWORD']]) {
script {
def remote = [:]
remote.name = 'xxxxxx'
remote.host = 'xxxxxx'
remote.user = USERNAME
remote.port = 22
remote.password = PASSWORD
remote.allowAnyHosts = true
# Execute your command and take return value in the init variable
init= sshCommand remote: remote, command: "cat /var/log/myFile | grep VALUE | awk '{print \$2}')"
echo "Initial Value: " + init
}
}
}
}
stage("Test") {
steps {
script {
test = sh(script "echo ${init}")
}
}
}
}
}
}
