stash unstash to transfer data in Jenkins from a build container to the other node

Question

I am having a Jenkins master running as a container on two virtual machine.

I am trying to run a build inside a docker container on a node so during the build process i had stashed my target folder to use it later on other node .In the job's log the stashing of folder was successful. when the build was finished the container is automatically destroyed then in the next step I unstashed that folder to achieve another stages in separate node but it didn't work..

I think unstash is not doing anything.

How do I transfer my target from the container to another node?

Below is the code written for pipeline:

node('docker') {
  stage('Checkout Code') {
      checkout scm
          }
  stage('Build') {
    withMaven( jdk: 'jdk_8', maven: 'maven 3') {
        mvn 'clean install'
        stash name: 'war', includes: 'x.war'
    }
  }

node('master') {
  stage('test') {
    withMaven( jdk: 'jdk_8', maven: 'maven 3') {
      unstash :	'war'
      sh 'mvn clean test'
    }
  }
 }
}

Can any one help me with this?

Thanks

I don't think that it is even getting stashed since the generated war should not be in the same directory where you executed mvn clean install.

I suppose the war to be under target.  It can be changed which includes: 'x.war' to includes: 'target/x.war' or go to the maven repository where the war is installed and stash the file from there:

withMaven( jdk: 'jdk_8', maven: 'maven 3') {
  mvn 'clean install'
  dir('<path to war>'){
      stash name: 'war', includes: 'x.war'
  }
}

I hope it will help you resolve your query.

I agree with @Shubham, I highly doubt if the folder was stashed in the first place.

Answer 3

Hey @Atul, Try keep your war under the target

Answer 4

Keep your war under target like this:

change includes: 'x.war' to includes: 'target/x.war'

Answer 5

Since the container gets destroyed once the job is done , i guess we are not able to store the stashed file, may be try to do a sftp or scp to master server from docker node or we can start a container by passing arguments to mount a specific directory of master so that file will get stored in master file system
