When I create a new Freestyle project in Jenkins, the default branch is "master".
Can Jenkins be configured so that the default branch is "main"jenkins default branch
When you configure a freestyle project, you also need to configure the section Source Code Management. In there you choose Git, and amongst other settings you enter the branch specifier. Per default it points to */master.
From the online help within Jenkins:
Specify the branches if you'd like to track a specific branch in a
repository. If left blank, all branches will be examined for changes
and built.
The safest way is to use the refs/heads/ syntax. This way
the expected branch is unambiguous.
If your branch name has a / in it make sure to use the full reference
above. When not presented with a full path the plugin will only use
the part of the string right of the last slash. Meaning foo/bar will
actually match bar.
If you use a wildcard branch specifier, with a slash (e.g. release/),
you'll need to specify the origin repository in the branch names to
make sure changes are picked up. So e.g. origin/release/

I have provided branch specifiers as shown in below image. If I remove the branch specifier with $BRANCH in it, job works perfectly(gets triggered) as anyone commits to develop or feature branches.
Now I also want that same job should also be able to build the project on any specific branch of choice. So I added a branch specifier and put $BRANCH in it. I have defined BRANCH as a string parameter and the user can give branch value as input when triggering the job manually.
But in this scenario even if the user gives a "bugfix112" job is still building develop branch. Or if earlier poll action had built the job on feature branch than even after providing user-input, the job will still build feature branch.
It seems like manual input has no effect. How can I configure a Jenkins job that can be triggered on poll SCM and also with user input for the branch parameter?
i also tried giving */$BRANCH,*/${BRANCH} but no success.
So I had raised above issue with Jenkins git plugin author and it looks that for the above scenario we have to use the multi-branch pipeline. In fact, I agree with the statement.
https://issues.jenkins-ci.org/browse/JENKINS-61074
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.
I Have been working on bitbucket and jenkins for android applications. I am having many branches in my repository and i want to track just my master branch in jenkins where it meets the following criteria. 1) When we push any code with name 'A' into master it should automatically trigger a build.2) when we push a code as name 'B' into the same master branch it shouldn't trigger the build. Is there a way to do it. I tried excluding branch by using :^(?!.release).*$ but it is picking all other branches too.
Can anyone help?
You can specify which branch to be built in your job like this:
If you don't want the build to occur for specific codes then you can add them in to the Excluded Regions
Go to Additional Behaviors under Git in your job configuration and select Polling ignores commits in certain pathsand add the paths to the files for those you want to ignore builds if any changes happen to them:
This should work!
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
We use TFS source control and have two build controllers (one VS2010 the other VS2012). We use the default build workflow template bar a few custom changes.
As we have many branches, how would we go about changing the workspace based on the desired branch?
I was thinking of adding a parameter for the branch ($\oursourcecontrol\branches\main) and then just passing it as a variable in to the get workspace part of the workflow.
Or is there a better way of doing it?
You currently can't and it is really a shame. It would completely break the Trigger support for CI and Gates checkins. You can use the TFS Community Build Manager to quickly clone and adjust build definitions to support multiple branches though.
What you could do, is to fetch more than you need (say $/Sourcecontrol/Branches/*) and then use a string-replace on any path parameter (like solutions to build, test settings file etc) to point them all to the correct solution. You'll probably need to do some templating like {BRANCH} so that you can easily replace these tokens.
The Git build template does support this on a Git repository, but you'd need TFS 2013 to make use of server side Git support.
I mapped the server path in the Repository tab at higher level that TFS branches are contained. Cloak rest of the branches not required for Get sources step except the branch to be built. And create variable to pass the branch name, check allow at queue time. Use this branch variable in build steps to make the build definition work for all the branches. You may need more than one variable based on your branches structure in TFS.
