I want to create the following flow:
I have some program which is making a REST CALL to one of my builds, it could make it any time in a day, but i don't want this my jennkins build to be executed immediately, only in a specific interval of time E.G between 3-5 AM, but only if it has been triggered by the REST Call.
Is there any plugin or a way to do it ?
The easiest way would probably be to do some PowerShell scripting and an additional job:
Create an empty dummy job (This will be the one you trigger through the REST api)
Create another job, which will be the one you actually want to execute within a specific interval of the day. Use a Cron Build Trigger
to setup when the job should execute in case of a trigger
Using the PowerShell Plugin and Run Condition Plugin, write some PowerShell code using the Jenkins REST api to fetch information about the "dummy" job. Here you will check whether the dummy job has run (triggered) or not today, and then you can decide with the Run Condition build step, if you want to proceed with the build.

I have 2 jenkins machines:
JenkinsA and JenkinsB.
I need a trigger in JenkinsA to trigger the execution of a project in JenkinsB. However I don't need to run remote job immediately. I need put it in queue and be able to schedule when it will run.
I also need send parameters from A to B.
Currently I am using the plugin:
https://wiki.jenkins-ci.org/display/JENKINS/Parameterized+Remote+Trigger+Plugin
This plugin allows build remotely and send the parameters, but it does not allow the execution schedule in the job of Jenkins B.
When using the build trigger and triggering the job remotely, you can append &delay=30sec (or any number of seconds) to the end of the build URL. This will allow the job to enter the quiet period and delay the build for the set period of time. the URL will look something like this JENKINS_URL/job/build?token=TOKEN_NAME&delay=30sec **or** /buildWithParameters?token=TOKEN_NAME&delay=30sec
I am new to Jenkins plugin development. M trying to write a plugin that should be executed before any Multi configuration type job runs in Jenkins.
In this plugin I want to write rules that will check what configuration parameters user has selected while submitting the job, based on selected parameters, I want to decide whether to allow the job to run or to restrict it.
User should be shown reason as to why that job cannot be run in the Console Output.
Does anyone have any ideas which class I need to extend or which interface I need to implement in order to get a hook into Jenkins job run?
You could look at the Matrix Execution Strategy which allows for a groovy script to select which matrix combinations to run. I would think if your script threw an exception it would stop the build.
For background, the multi configuration projects run a control job (or flyweight) which runs the SCM phase then starts all the actual combinations. This plugin runs after the flyweight SCM checkout.
If nothing else, this will give you a working plugin to start from
Disclaimer: I wrote this plugin
Blocked queue job plugin was what I needed
Out of the box that plugin supports two ways to block the jobs -
Based on the result of last run of another project.
Based on result of last run of the current project
In that plugin the BlockQueueItemTaskDispatcher.java extends Jenkin's QueueTaskDispatcher providing us a hook into Jenkins logic to allow or block the jobs present in the queue from running.
I used this plugin as a starting point for developing a new plugin that allows us to restrict project based on parameters selected and the current time. Ultimate goal is to restrict production migrations from running during the day.
Overriding the isBlocked() method of QueueTaskDispatcher gave access to hudson.model.Queue.Item instance as an argument to me. Then I used the Item instance's getParams method to get access to build parameters selected by the user at runtime. Parsed the lifecyle value from it. Checked the current time. If lifecycle was Production and current time was day time then restricted the job by returning non null CauseOfBlockage from isBlocked() method. If that condition was false, then returnedCauseOfBlockage as null allowing the queued job to run.
I have a Jenkins job that should not start building until another job has been built successfully at least once. They are not related per se, so I don't want to use triggers. Is there a way to do this?
Some background: I'm using SCM polling to trigger the second job. I've looked at the Files Found Trigger plugin, but that would keep on triggering the second job after the first on has been built. I've also found the Run Condition Plugin, but that seems to work only on build steps, not on the entire build.
Update - The second job copies artifacts from the first job. As long as the first job has never completed successfully, the Copy Artifact step fails. I am trying to prevent that failure, by not even attempting to build the second job until the first job has completed once.
One solution is to use the Build Flow plugin.
You can create a new flow job and use this DSL:
I've used 10 in the retry section but you can use any numbers.
This flow job can be triggered by monitoring the same SCM URL of your second job.
Update, here is a second solution.
You can use the HTTP Request plugin.
If you want to test that your first job has been built successfully at least once, you can test this URL:
http://your.jenkins.instance/job/your.job/lastSuccessfulBuild/
One example:
As my build has never been successful, the lastSuccessfulBuild URL doesn't exist. The HTTP Request changes my build status to failure.
Does it help?
The Block queued job plugin can be used for this: https://wiki.jenkins-ci.org/display/JENKINS/Block+queued+job+plugin
Is there a way to trigger a scheduled job?
I am building a pipeline of connected jobs which trigger each other once complete. I want one of the jobs to be scheduled to run at a particular time of the day. So I want to be able to essentially add to a queue to trigger at a later time.
Is that possible?
Cheers
To schedule a Jenkins job to run at a specific time, go to the job's landing page, click Configure from the left-side menu, scroll down to 'Build Triggers' section and pick 'Build Periodically'.
There you can specify the cron job formatted string to denote when and how often you'd like this first job to be scheduled for running.
If that job is not the first job in line, you can always use 'Quiet Period' option under 'Advanced Project Options' which puts in a delay in that job before the build steps actually run. You can specify the number of seconds you want that job to wait for before it actually executes.
This plugin seems to be piggybacking on the 'Quiet Period' feature though I haven't tried it myself: https://wiki.jenkins-ci.org/display/JENKINS/Schedule+Build+Plugin. You might have luck using it to your advantage.
You could use the Jenkins Workflow plugin suite (mentioned in your tag, perhaps unintentionally). It has a sleep step. If you wanted the next stage of the pipeline to run at a particular time of day, rather than after a fixed interval, you could do some simple computation with java.util.Calendar to determine the seconds between now and then.
In a single Jenkins job, we can trigger a build by specifying a schedule and also by polling. But then, in both the cases, the build is triggered, and the deploy operation that I have configured as a post-build step (using PostBuild Task plugin) also happens. I want that the build happens whenever a change is detected by polling, but deploy should happen only according to the schedule I have provided.
Is it possible to do it in a single job, or do I have to configure 2 separate jobs for them ?
You said you are using PostBuild Task plugin. This allows to do a regular expression on the console log to determine whether to execute a task or not.
Builds started by schedule will have Started by timer at the top of the log. All you need to do is add this expression to your PostBuild step under "Log Text" field. If you are already using some criteria in there, click "Add" button to add another "Log Text" field, and use the "AND" operator between them
It will be cleaner to do it in 2 jobs. However, if you really need to have it in one job, you could use a combination of Jenkins plugins to do the job.
Use EnvInject Plugin to expose the BUILD_CAUSE and/or BUILD_CAUSE_SCHEDULED* environment variable(s). (This may not be necessary, you might be able to reference the Jenkins variables within the Jenkins configuration by default)
Use Flexible Publish plugin, post-build action, to set up a conditional publish step when BUILD_CAUSE == SCHEDULED, or when BUILD_CAUSE_SCHEDULED == true. (Just test one condition.) Note that you'll need to use Jenkins' expression syntax, like so:
${ENV,var="BUILD_CAUSE_SCHEDULED"}
* BUILD_CAUSE_SCHEDULED is not its real name, you'll need to find this out on your own, sorry.
