When I create a plain pipeline project I have the option to periodically poll the scm and if changes are detected, the build is run. that worked well for me.
Now I created a multibranch pipeline and added 2 branches. However, in the configuration I can not set the same as in the normal pipeline project, because it tells me I can only view the configurations of the sub-branch-projects.
Maybe I'm also doing it wrong, so I try to tell you what I actually want to achieve.
I have a PHP project inside of a Git repository. There are two branches that I want to be built on new commits (when pushed to the main repository)
The main repository resides on a self hosted version of Bitbucket Server. If possible, I want to avoid hooks and let Jenkins poll for changes on the bitbucket server. So how can I achieve that?
You just need to check the option Periodically if not otherwise run trigger at the multibranch level. This replaces per-job polling, because it also detects new branches and the like.
If I got you right, all you want to do is to build ONLY these 2 branches?
If so, under "Branch Sources" just click the "Advanced" and fill in the textfield "Include branches" your branches e.g. test test2 (note the space between the branch names)
Actually you'll have configure SCM pollig (the way you expect it) in the Jenkinsfile itself. It's the properties DSL elelement that handles the configuration:
properties([
pipelineTriggers([pollSCM('H 20 * * 1-5')])
])
Anyways I highly suggest to have a closer look at the Pipeline Snippet Generator:
<your-jenkins-url>/pipeline-syntax/
it s easy to miss but extremely helpful and it s populated based on your currently installed plugins. There you will also find a comprehensible set of options available for properties

I have a build job on Bamboo that has parameterized branches. All branches (for e.g. feature branches created by developers at will) have a default set of parameters, and specific branches override some of them. Note that once I set a variable for a given branch to a certain value, every build of that branch takes that value. I'm trying to recreate this in Jenkins, but there doesn't seem to be a way to do so.
I created a multibranch pipeline and defined the parameters in my Jenkinsfile with suitable defaults. However, the only way I can override the parameters for a branch is to click "Build with parameters" and update them. That works for that build, but next build that gets triggered reverts back to using the default values. This seems like such a basic use case that I feel like I must be missing something or misconfigured the project somehow, considering I don't have any experience using Jenkins before trying this. Thanks in advance for your help!
I have a project which has multiple jenkins files and a jenkins with the bitbucket team plugin. The whole point is to separate staging from release.
When I push on bitbucket a change on a branch that both jobs monitor ( lets say master ) then both jobs will trigger as expected. I would like to disable this trigger on one of the jobs and force it to be manual only (lets say on job A which is the release. The jenkinsfile defined the release process but should be run only manually ) .
so far in the team configuration I cannot stop the trigger but neither in a jenkinsfile I can set a property ( this#ignorePostCommitHooks ) and make it work. ( I do setup it. But it does nothing ). Is there a way to configure the job triggering?
Also a side question, Jenkins offers this option
But even after setting it when I save the configurations and jenkins starts looking in the repository for matching projects / branches it will start building any branch it finds. Is there a way for this option to actually work?
Thank you in advance.
Wrapping it into an all match make it work.
We have Jenkins set up with 7 multibranch pipeline projects, each building off the same git repo, but for different target platforms. Each of these multibranch pipelines builds a number of branches. We currently set which branches each multibranch pipeline builds by using the following property in the multibranch project configuration:
Branch Sources -> Git -> Behaviors -> Filter by name (with wildcards)
Currently, each multibranch pipeline has the same string of branches in this Filter by name (with wildcards) field. Each time we want Jenkins to start building a new branch, we go through all 7 multibranch project configurations and update this field to include the new branch.
It's a bit of a pain to go through each configuration and change this field every time, since we always want each configuration to have the same list of branches. Is it possible to simply use some type of a variable in this field? This way we only would need to change one location instead of trying to keep 7 different configurations in sync with each other, which is prone to error and also a bit of a pain.
Thanks for your help!

Rather than filtering with wildcards, you could try filtering branches with regular expression. In our case, pattern like:
(master|develop|release.*|feature.*|bugfix.*)
has been working well to cover the repository. That is, assuming that you follow Git Flow or similar methodology. Unfortunately, there is no simple way to sync the configuration between MultiBranch Pipelines build from one repository. Neither Multibranch Pipeline, nor Organization plugins are designed to work with Multiple Jenkinsfiles.
Also, you can try to sync only the branch configuration between Projects using Jenkins script console. Most of the Job configuration does not have to be set on Project level. For instance, you can create shared script (or shared library) to would be sourced by other jobs, to set the same job properties on each of them. See How do you load a groovy file and execute it for details.
if you want to use the wildcard you can provide like below:
In this example it will discover only qa and dev branch.
NOTE: You have to use "Discover branches" also with "filter by name (with wildcards)" behaviour.
After creating a Multibranch Pipeline in Jenkins I can easily tell it to poll for changes or additions of any branches and it will automatically create jobs for and build those branches. I told the Multibranch job to also discover tags, so it automatically creates jobs for each tag, which is great.
Is there a clean way for Jenkins to automatically build those tags as well, instead of me having to trigger them manually? As you can see below, the job for the tag is there, but I have to manually build it.
I would have commented with this, but I don't have enough reputation. I believe this is a duplicate of Jenkins Multi-branch pipeline doesn't schedule tag jobs. See my answer there, copied below.
In short, if you build and install the Jenkins plugin available at https://github.com/AngryBytes/jenkins-build-everything-strategy-plugin then you can add a Build Everything strategy which will automatically build tags.
Not automatically triggering a build for discovered tags seems to be by design according to JENKINS-47496. Stephen Connolly offers an explanation and suggestion for what you might do:
Stephen Connolly added a comment - 6 days ago
Tags are not built by default (because otherwise you could have a
build storm when checking out a repository) and worse, the order tags
will be built in is unpredictable... and you might have a Jenkinsfile
that deploys to production when a tag is built.
There is an extension point in branch-api called BranchBuildStrategy
which - if implemented - will allow deciding whether to build tags.
See
https://github.com/jenkinsci/github-branch-source-plugin/pull/158#issuecomment-332773194
for starting point on how to create such an extension plugin... I
believe there is some work on one at
https://github.com/AngryBytes/jenkins-build-everything-strategy-plugin
As #tommy-ludwig says, you need an additional plugin providing a Build Strategy ; since his original post, Stephen Connolly has published the Basic Branch Build Strategies Plugin which among others provides a strategy to build tags.
If, like me, you don't care if the tags show up on a separate tab, you just want the tags to be visible when your various branches are being built (which implies that your tags will be built), then do this:
In your multibranch pipeline's configuration, go to "Branch Sources", "Git", "Behaviors", and add "Advanced clone behaviors". By default, when you add this you will see that "Fetch tags" is checked. Voila!
I have multi-configuration project in Jenkins. My git repository have different branches. For example:
dev
stage
bug/code1
feature/code2
etc...
I want to create different Post build tasks, Publish HTML reports etc for each branch.
What is the problem? I changed configuration for stage branch. All works fine only before Branch Indexing. After this process, custom configuration for each branch replaced by multi-configuration project. It means if I added specific task only for stage branch, after Branch Indexing task will be removed.
Multi-Branch Project Plugin says this:
Sub-projects appear to be configurable, but they will be overwritten
by branch indexing if you manually modify them. There is no clear way
to remove or hide the configuration option on sub-projects (except
maybe with project-based matrix authorization??), though version 0.1.x
of this plugin accomplished that via some trickery that is not
possible in newer versions.
So my question is: How I can create custom configuration for each branch? Or what is the best solution for this? Maybe I should create different projects for stage, dev branches?
Thank you.
We have the similar situation like you, more than 10 branches need to be maintained. Instead of using multi branch plugin, we use job dsl to create the jobs for each branch.
For example, hello_branch1, hello_branch2....
Inside our job dsl project, we save the different json config for the different branches. In your case, you can think we save the post build script, or report to be published....
This will make sure the generated jobs are standalone and will not affect each other.
