I'm new to Jenkins. I have a stack of 5 different jobs. I want them to execute endlessly, meaning the first one will start after successfull finish of 5th. Is there a way to do this? Is Jenkins pipeline plugin the right tool to make this?
If you already have 5 non-pipeline jobs, the easiest way is to
set a downstream job on each job as it makes a loop.
In the configuration page of each job, Add post-build action > choose Build other projects > Enter a name of a downstream job.
in pipeline there is a build step (https://jenkins.io/doc/pipeline/steps/pipeline-build-step/), but I haven't tried if this can take trigger itself (most probably).

Is there a possible to prevent the full jenkins job from running, that is periodically scheduled; if there is no SCM changes since the last build.
For example,
There is a daily night build, to create a build. The completion of this job triggers(upstream project) the automation testing job for that build.
I would like to be able to have two things
Stop the 1st build job, if there is no SCM change since the last job
2nd upstream automation test job runs only if it has not run for 1 week. (after it has been triggered by the 1st Job)
Thanks in advance
The first part is simple, instead of "Build periodically" set to "Poll SCM" with the same schedule. It's exactly what it does: periodically checking for changes and only running the job if there were some.
The second part (triggering another job with a time constraint) is more complicated. One option is "Throttle builds" (to 1 per week) in addition to your usual build triggering scheme. Another one is "Trigger builds remotely (e.g., from scripts)" option and checking whether required conditions are met in some sort of script or service.
For the first
Did you try the poll the SCM every night? If no changes, the Jenkins job wont start.
0 23 * * *
Will run every night at 11 p.m
for the second
use the following plugin : https://wiki.jenkins.io/display/JENKINS/Run+Condition+Plugin
i am new to Jenkins , i need to execute one job that run's another multiple jobs in parallel were it should not stop even if one job fails.
i am not sure how to achieve it. After googling i can achieve by 3 ways Multi-Job plugin , Pipeline multiple Jenkins jobs , Build after other projects , Build Flow Plugin.
can any body please provide me the correct way.
Update : i am trying to achieve this using the pipeline plugin , can any body suggest me were it was correct choice ?..Please suggest!..
We use the Parameterized Trigger Plugin to do this.
In your build configuration add a Trigger/call builds on other projects build step. Add the names of the builds you want to trigger as a comma separated list and make sure that the Block until triggered projects finish their builds box is unchecked. Your build will trigger each of the listed builds, however note that your parent build won't wait for them to finish it will just trigger them and then perform the rest of it's buildsteps so if you have buildsteps.
If you do want to wait then check the block until triggered builds finish box, but set the options for when to fail the build, build step or mark the build as unstable appropriately.
If you need to pass parameters to the jobs you can add parameters using this plugin. If your downstream jobs need different parameters for different jobs you can click the add trigger button which adds another project to build where you can specify different options.
If these other jobs are follow up jobs to the current job and you don't need to wait for them to finish you can also achieve what you want to do by using the post build action build other projects, but again this occurs after the current job and you won't be able to use the results.
can any body please provide me the correct way.
I wouldn't approach using Jenkins with a "one correct way" mentality. Often times the requirements of your build will dictate which method or plugin you use in your build configurations.
The job can start other jobs via the jenkins api.
updated Answer : i used pipeline plugin to achieve my task and tuffwer was right to if u have paramaterized trigger plugin!..
Jenkins to run 10 jobs sequentially and few parallely and let say 1-2 jobs are successful and job3 failed. I fixed the job3.Now I want to again trigger the job but only want to trigger it from job3.All 10 jobs have string parameter.
I can pick an choose what jobs to trigger. how can I achieve it.Please help.
The whole point of CI is to have multiple runs frequently, so that in next run you can see them all stable. Not sure why you wanted to do this. However, You can take 2 approaches.
You can use conditional Step plugin along with multiphase plugin,
wrap you build step with condition and pass whether you want to run
it or not. only if the condition is passed then the individual jobs
will be triggered.
You can use jenkins-cli and trigger the jobs
which ever you wish.
I'm trying to build the above 'delivery pipeline' using Jenkins.
Every job excluding "Manual Step" will run when upstream jobs end with success. My problem is that I cannot do 'join'
between the two jobs (run "Manual Step" and "Auto Step" in parallel and wait for the 2 to finish sucessfully before "Final Step").
Is there any way to make this possible with Jenkins? Maybe some plugin?
This question is very similar to this one: How do I make a Jenkins job start after multiple simultaneous upstream jobs succeed?
But what I really want is to know if it is possible to parallelize two different types of jobs (jobs who run manually and jobs who run automatically).
Since it's been a time since I posted the question and it seems there is no elegant solution to the problem I'm going to share my work-around:
First, I edited the two jobs so that a new file is created whenever the Manual and Automatic Jobs finish successfully (1 file for each job).
Next, I put a validation on the 'Final Step' job to only run if the two files are created. If the two files are created, proceeds to the 'Final Step' job instructions
I have a job that, when complete, starts another job through post-build actions:trigger parametrized build. However at times, I wish to just run one specific job manually (not through the timer) without chaining off the rest of the jobs. How would I accomplish such a task.
Thanks in advance!
You can't in your current setup.
You want the Flexible Publish Action to make your post-build action conditional (probably based on parsing the console log for indication that the build is manual)
