I have scheduled the jenkins job at 7 pm at evening... But whenever the changes observed in
SVN then only the job should run or else it should not trigger even the job is scheduled at 7 pm
Please help me with the powershell script to not run the job or the job should exit when no change occur in SVN even scheduler is there also... Please help me out with this..

I'm using the polling scm (git) plugin to trigger jobs. I've set the quiet period to 30 seconds for a specific job.
When I commit:
the job indeed sits in the "build queue" for 30 seconds.
I cancel it, and it goes away
However the polling scm plugin seems to re-trigger and then build the job. at the next poll period
How do I cancel the job without letting it start, and then canceling it?
This is not possible with timer triggered scm polling.
The reason is, that on each poll jenkins will compare the remote to the local revision and will find out that the remote revision it is newer thus triggering a build. Aborting the build before a checkout or update doesnt change the local revision so it will retrigger a build on the next poll triggered by the timer.
A solution is, to make use of post-commit hooks.
Post-commit hooks are configured on the remote machine and are basically scripts that run after a commit has happened. As you can trigger a poll by calling some url on your jenkins server, its merely some configuration on the scm server to trigger a poll exactly after a commit has happened. That way, after an abort, jenkins will only trigger a poll on the next commit to the repository.
Theres usually some hints how to setup this in the documentation of the various scm plugins, i.e. the git plugin.
I have a scheduler that makes builds of about 20 tasks at midnight and uses the same job recursively. However, when one job fails it has a postbuild job, that finds the culprit in svn and sends mails with the details to the culprit. My Problem is, that before the postbuild job can fetch the infos from the logfiles of the failed job, the scheduler already started a new one and all logs etc are deleted. How can i make jenkins wait to start the next job until the postbuild is finished.
There is an option in the jenkins post build plugin - named as "Block Until the triggered job".
This should work
I scheduled a job in Jenkins to run each day at 1800 stopping some process. After I made configuration in Jenkins I build the job but it executed immediately and then moved over to the schedule. Can I prevent that first run somehow so let's say I build job at 1400 but it only executes at 1800 and not at 1400 when built?
I'm trying to setup a Jenkins server to monitor a bunch of cron jobs. I will launch most of them using the Jenkins freestyle project however some of the cron jobs will be remote so they will be communicating back as external jobs. How can I get warnings when those external jobs fail? and can I set the schedule they should be on so I can get warnings even when they don't run?
Thanks.
To my understanding and to answer your latter question, you can setup an overall cron scheduler in your Jenkins monitoring job in such a way it runs exactly during the time you expect the remote cron to execute . Say ur remote job executes at 1 pm every day u can configure your Jenkins monitor cron to kick off a build at 12.45 pm or 1 pm based on ur needs.
A solution to your first question could be to have a wrapper script execute the remote invocation of jobs so tht u can monitor the return value of tht remote invocation.
Like if you have an ant script invoke the Java command remotely, it will return a non zero if the Java command failed execution and the ant script will also fail and so your Jenkins job executing the ant script will fail and u will be notified about it.
I can help you with further specific steps if you did not follow me
Suppose i have set a Jenkins job from 12 pm to 1pm. Let us say job has been started. Now suppose Administrator has set Jenkins to be restarted at 12:30 PM. What would happen- will my script gets paused or gets failed?
Surely your builds will abort if jenkin is going for a restart/shutdown. I have seen some cases where you lose even the build log for that particular build.
(jenkins_url)/safeRestart. This will allow all running builds to complete.
(jenkins_url)/restart will force a restart without waiting for builds to complete.
