Jenkins Parallel Trigger and Wait - jenkins

Question

I have 4 jobs which needs to be executed in the following sequence
JOB A
|------> JOB B
|------> JOB C
|------> JOB D
In the above
A should trigger B & C parallely and C inturn triggers D.
A should hold the job as running till all 3 of them completed.
I tried the following plugins and couldn't achieve what I am looking for
Join Plugin
Multijob Plugin
Multi-Configuration Project
Paramterized Trigger Plugin
Is there any plugin which I haven't tried would help me in resolving this. Or is this can be achieved in a different way. Please advise.

Answer 1

Use DSL Script with Build Flow plugin.
try this Example for your execution:
build("job A")
parallel
(
{build("job B")}
{build("job C")}
)
build("job D")

Answer 2

Try the Locks and Latches plugin.

Answer 3

This may not be optimal way, but it should work. Use the Parameterized Trigger Plugin. To Job A, add a build step (NOT a Post Build Action) to start both Jobs B and C in the same build step AND block until they finish. In Job C, add a build step (NOT a Post Build Action) that starts Job D AND blocks until it is finished. That should keep Job A running for the full duration.
This isn't really optimal though: Job A is held open waiting for B and C to finish. Then C is held open until D is finished.
Is there some reason that Job A needs to remain running for the duration? Another possibility is to have Job A terminate after B and C are started, but have a Promotion on Job A that will execute your final actions after jobs B, C and D are successful.

Answer 4

I am trying to build a same system. I am building a certification pipeline where I need to run packager/build/deploy jobs and and corresponding test jobs. When all of them are successful, I want to aggregate the test results and trigger the release job that can do an automated maven release.
I selected Build pipeline plugin for visualization of the system. Initially tried with Parameterized trigger Plugin with blocking builds. I could not setup archiving the artifacts/fingerprinting and downstream build relationship this way since archiving the artifacts works only in postbuild. Then I put the Parameterized trigger in Post build activity. This way I was able to setup downstream builds, fingerprinting, aggregate test results but the build failures were not bubbling to upstream job chain and upstream jobs were non blocking
I was finally able to achieve this using these plugins-
Build Pipeline
MultiJob Plugin
FingerPrint Plugin
Copy Artifacts Plugin
Join Plugin
I'm using Jenkins 1.514
System looks like this
Trigger Job --> build (and deploy) Job (1..n) ---> Test Job (1..n)
Trigger Job -
Create as MultiJob and create a fingerprint file in shell exec
echo date +%s > fingerprint.txt
Trick is that file needs to be archived during the build, to do that execute this script-
ARCHIVEDIR=$JENKINS_HOME/jobs/$JOB_NAME/builds/$BUILD_ID/archive
mkdir $ARCHIVEDIR
cp fingerprint.txt $ARCHIVEDIR
Create MultiJob Phase consisting of build/deploy job.
Build/deploy job is itself a multijob
follow the same steps for creating build/deploy job as above relative
to fingerprinting.
Copy the fingerprint.txt artifact from upstream job
Setup MultiJob phase in deploy job that triggers the test job
create a new fingerprint file and force archive it similar to above step
Collect Junit results in the final test job.
In the trigger Job, use Join Plugin to execute the Release Job by choosing 'Run Post Build Actions at join' and execute the release project only on stable build of Trigger Job.
This way all the steps are showing up in Build Pipeline view and Trigger job is blocking for all downstream builds to finish and sets its status as the worst downstream build to give a decision point for release job.

Multijob Plugin
If you'd like to stop the mess with downstream / upstream jobs chains definitions. Or when you want to add a full hierarchy of Jenkins jobs that will be executed in sequence or in parallel. Add context to your buildflow implementing parameter inheritance from the MultiJob to all its Phases and Jobs. Phases are sequential while jobs inside each Phase are parallel.
