I have created a job in the Jenkins for the .net component. I want a condition or feature in the Jenkins to check if the repo of that component is updated by the SVN or not. If code is updated in the SVN then only that component should be build. By this way, I want to configure multiple jobs.
You have to set the job in order to pull from an SVN Repository.

You will be able to setup your pulling frequency, the basic poll configuration will check for new commit in all the SVN repositories checked out by your job.

I have a free style project which will trigger on commits. I have kept poll scm which polls for commits in remote repository. This jenkins job actually make some changes to a file after checkout and then commits+push back to remote repository.
This push by jenkins job is actually triggering back a new build due to scm poll for new commits is set in job. I want this job not to trigger again for self commit by job itself
It is not clear if you are using Git. In case you are and expect that the file will be always be changed by Jenkins, Git plugin in freestyle has options to ignore certain file paths.
If this specific file is expected to edited by user other than Jenkins than only solution I can think of is through conditional logic in jenkins pipeline-as-code.
Is there any way to make Jenkins builds after each commit in any branch ?
Because i found in my project's configuration that Jenkins run build only after detecting commits in specific branch or in the default ( eq to master in git ).
PS: i'm using mercurial and Jenkins file.
Should i change project type ( new item type in Jenkins ) or are there any modifications in configs.
There are two things that you should check for this (I haven't work with Mercurial)
Does Mercurial has the option to create webhooks?
There is a jenkins plugin for Mercurial? (I think there is)
You must configure on the mercurial site the webhook pointing to Jenkins and give the point to the job you want to run, and on which events does it will fire. On the Jenkins side you must configure on the job who it will behave.
For example, with GitLab, the plugin has an option configured on the "Build Trigger" section where you configure the events and the branches that fires the job. In GitLab, in the repository you create the webhook, that is only a URL pointing to the Jenkins job.
I got this solution and it worked for me.
with Mercurial, we can use the "tip" keyword.The tip revision is the most recent changeset in the repository. It is the most recently changed head.
I have around 10 repositories that I would like to poll. If a folder is a added in the root folder of any repo, I'd like to trigger a certain build, (the same).
I thought using the Poll SCM plugin but it requires one job per repo and it's not scalable.
Is there any clean way to do this and any plugin that would help?
EDIT: I have a job generating debian packages from folders that are in my 10 repositories (each folder corresponds to a separate package). When a new folder is added, it means a new package is.
I would like then to trigger a packaging build so developers can fetch it from our apt repository without waiting the nightly build
You can use this plugin:
https://wiki.jenkins.io/display/JENKINS/Pipeline+Multibranch+Plugin
As per the manual:
Enhances Pipeline plugin to handle branches better by automatically
grouping builds from different branches. Automatically creates a new
Jenkins job whenever a new branch is pushed to a source code
repository. Other plugins can define various branch types, e.g. a Git
branch, a Subversion branch, a GitHub Pull Request etc.
See this blog post for more info:https://jenkins.io/blog/2015/12/03/pipeline-as-code-with-multibranch-workflows-in-jenkins/ "
I have development code repository at bitbucket and another test script code repository at bitbucket. Now I have setup a Jenkins job by linking test code repository. Is there any way to trigger jenkins job automatically on change in development repository ?
You can add the BitBucket Plugin to your Jenkins instance. It will allow you to configure a webhook in BitBucket that will then trigger any Jenkins job listening for that webhook. The plugin's page has a detailed breakdown, but the basics are;
In your repo in BitBucket, create a new Webhook using your Jenkins' url. I believe the url is generally http://[your jenkins url]/bitbucket-hook/
Make the trigger a repo push.
In your Jenkins job, check the box "Build when a change is pushed to BitBucket" under the Build Triggers section.
Now any time you commit to the repo you created the Webhook on, that Jenkins job will be run.
You can also limit what branches trigger commits by parameterizing your Jenkins build to ignore certain branches / keywords / etc if that's something you need for your specific project.
Builds by source changes
You can have Jenkins poll your Revision Control System for changes. You can specify how often Jenkins polls your revision control system using the same syntax as crontab on Unix/Linux. However, if your polling period is shorter than it takes to poll your revision control system, you may end up with multiple builds for each change. You should either adjust your polling period to be longer than the amount of time it takes to poll your revision control system, or use a post-commit trigger. You can examine the Polling Log for each build to see how long it took to poll your system.
Alternatively, instead of polling on a fixed interval, you can use a URL trigger (described above), but with /polling instead of /build at the end of the URL. This makes Jenkins poll the SCM for changes rather than building immediately. This prevents Jenkins from running a build with no relevant changes for commits affecting modules or branches that are unrelated to the job. When using /polling the job must be configured for polling, but the schedule can be empty.
I am creatig a new Jenkin Job. This job is using SVN version control and coding is done in Java and also i am creating jar using ANT.
Now I would like to create job that detects changes in svn repository.
i.e., When ever the developer changes the code jenkins job need to executed automatically.
Can any one please help me.
Thanks
Have you given Subversion Plugin a read?
Post-commit hook is of concern to you -
Jenkins can poll Subversion repositories for changes, and while this is reasonably efficient, this can only happen up to every once a minute, so you may still have to wait a full minute before Jenkins detects a change.
To reduce this delay, you can set up a post commit hook so the Subversion repository can notify Jenkins whenever a change is made to that repository.
