How do I retrieve the URL of a Jenkins downstream job without waiting for the job to finish? I can access the downstream job in the Jenkins web interface, but I cannot retrieve the URL immediately in the upstream pipeline.
my_job = null
my_job = build job: 'Downstream Job', wait: false, propagate: false
my_job_url = my_job.getAbsoluteUrl() // my_job is still null
Is this not possible?
Given what #roman said in the comment, JENKINS-31392 is the best workaround.

I have a master job which triggers multiply downstream jobs. If some of the downstream jobs fail, I don't want to have failed upstream job. Is there any condition I could set?
Because of that one failed job, I have this status of upstream job, and I want it to be success.
Ok if you want the the downstream jobs are success or not and you don't want to wait until those finish. then you can use in your master jobs in build job command propagate: false, wait: false
I have an old classic ui jenkins pipeline. now i need this pipeline to be triggered on the completion of other pipelines. And get the upstream pipeline information in this old pipeline.
I know how to set the upstream build trigger in the jenkins pipeline. However i cannot find a way to get the upstream build information (eg, project name, git commit).
When i output the env variables in downstream pipeline, i can only see the BUILD_CAUSE=UPSTREAMTRIGGER which is not useful for me.
Trigger Downstream Job With Parameters
The old job would need to be updated to be parameterised, then you can pass the required information as parameters when you build the downstream job.
Example:
build job: "DOWNSTREAM_JOB_NAME",
parameters: [string(name: 'upstreamJobName', value: env.JOB_NAME),
string(name: 'upstreamJobVar', value: "${upstreamJobVar}"]
Trigger Downstream Job Without Parameters
When parameters are not being send from triggering upstream job, then we can get some of the upstream information in the downstream job like this:
currentBuild.upstreamBuilds[0].projectName
All available methods for upstreamBuilds information can be found here
I have a pipeline which triggers a jenkins freestyle job.
How to access the pipeline name from the freestyle job.
I tried using ${BUILD_CAUSE} but it shows the value as UPSTREAMTRIGGER.
How to get the pipeline name?
JOB_NAME may contain the name of the job that you're after, unless it was triggered by an upstream job.
See a list of generic Jenkins environment variables that are available in most builds. The best way to find out what environment variables are available is to run sh 'printenv' in the steps.
If you need the name of the upstream job in a downstream job, I'd suggest setting a parameter on the downstream job and then referencing it when you trigger the job.
e.g. Upstream Pipeline job:
...
step {
build job: 'freestyle-downstream-job', parameters: [
string(name: 'upstream_job_name', value: "${JOB_NAME}")
]
}
...
I have an upstream project in Jenkins which calls in sequence some downstream projects with the "Trigger/call builds on other projects" plugin.
How can I automatically abort a build of any downstream project when I perform the aborting of the upstream project?
If the upstream is aborted, the downstream is still running and I want a different behaviour.
Thanks.
As mentioned in my comment, you can have downstream jobs listen to upstream jobs instead of having upstream jobs trigger downstream jobs. When it comes to parameters, the following groovy code example can be used to retrieve them:
def up_stream_cause = currentBuild.rawBuild.getCause(hudson.model.Cause$UpstreamCause)
if (up_stream_cause != null ) {
def up_stream_run = up_stream_cause.upstreamRun
def parameters_action = up_stream_run.getAction(ParametersAction)
def parameters = parameters_action.getParameters()
}
Alternatively, you can of course simply build the downstream build during the upstream build using the following groovy code:
build job: 'job_name',
parameters: [
[
$class: 'StringParameterValue', name: 'parameter',
value: 'value'
]
]
Both of those solutions allow you to not trigger a downstream build when your upstream build fails, aborts or is unstable.
You can review:

Pipeline jobs can by stopped by sending an HTTP POST request to URL endpoints of a build.
BUILD ID URL/stop - aborts a Pipeline.
BUILD ID URL/term - forcibly terminates a build (should only be used if stop does not work.
BUILD ID URL/kill - hard kill a pipeline. This is the most destructive way to stop a pipeline and should only be used as a last resort.
This last option is quite effective
I have an upstream pipeline which is calling another downstream pipeline
build job: "/org/projectA/master",
parameters: [[$class: 'StringParameterValue', name: 'variable', value: 'value']],
wait: true
In my downstream pipeline, there is a step to ask for approve
input "Deploy to prod?"
Currently the job is paused in the downstream pipeline waiting for approve, but in my main job (upstream pipeline), it is just waiting for sub pipeline to finish, doesn't show any message for approver. So is it possible to display the interactive input in my main pipeline? then the approver doesn't need to click to the sub pipeline to check the status.
BTW, I cannot move the input to main pipeline, cause there are other steps after it in the sub pipeline.
Thanks in advance for any suggestion
I really wouldn't recommend it, but there's a way via Jenkins Remote API -
Jenkins input pipeline step filled via POST with CSRF - howto?
curl -X POST -H "Jenkins-Crumb:${JENKINS_CRUMB}" -d json='{"parameter": {"name": "${PARAMETER_NAME}", "value": "${PARAMETER_VALUE}"}}' -d proceed='${SUBMIT_CAPTION}' 'http://j${JENKINS_URL}/job/${JOB_NAME}/${BUILD_ID}/input/${INPUT_ID}/submit'
The question would be how would you run this? A new input in the upstream job? Run when?
It might be more useful to divide the downstream job into two and run the actual deploy only when user accepts the input in the upstream job.
