Jenkins pipeline share information between jobs

Question

We are trying to define a set of jobs on Jenkins that will do really specific actions. JobA1 will build maven project, while JobA2 will build .NET code, JobB will upload it

Answer 1

There are two ways to share info between jobs:

1. You can use stash/unstash to share the files/data between multiple jobs in a single pipeline.

   stage ('HostJob') {
       build 'HostJob'
       dir('/var/lib/jenkins/jobs/Hostjob/workspace/') {
           sh 'pwd'
           stash includes: '**/build/fiblib-test', name: 'app' 
       }
   }
   
   stage ('TargetJob') {
       dir("/var/lib/jenkins/jobs/TargetJob/workspace/") {
       unstash 'app'
       build 'Targetjob'
   }
   

   In this manner, you can always copy the file/exe/data from one job to the other. This feature in pipeline plugin is better than Artifact as it saves only the data locally. The artifact is deleted after a build (helps in data management).

2. You can also use Copy Artifact Plugin.

   There are two things to consider for copying an artifact:

   a) Archive the artifacts in the host project and assign permissions.

   b) After building a new job, select the 'Permission to copy artifact' → Projects to allow copy artifacts: *

   c) Create a Post-build Action → Archive the artifacts → Files to archive: "select your files"

   d) Copy the artifacts required from host to target project. Create a Build action → Copy artifacts from another project → Enter the ' $Project name - Host project', which build 'e.g. Lastest successful build', Artifacts to copy '$host project folder', Target directory '$localfolder location'.
