Jenkins - how to build a specific branch

Question

This isn t as simple as just doing a parametrized build  I ve already got a specific build process that will build and deploy whenever any of these branches are pushed to GitHub     So if I ve just pushed develop and it built successfully  how do I trigger a manual build and have it pull feature my-new-feature  without doing a git push   I tried enabling parametrized build  adding a new string called branch  and then adding a new branch specifier     branch  I then ran a build and set branch to feature my-new-feature and it still pulled from develop   I d appreciate any help

I don t think you can both within the same jenkins job  what you need to do is to configure a new jenkins job which will have access to your github to retrieve branches and then you can choose which one to manually build    Just mark it as a parameterized build  specify a name  and a parameter configured as git parameter    and now you can configure git options

There will be an option in configure under Build Triggers  Check the GitHub Branches  A hook will be created and then you can build any branch you like from Jenkins when you select github Branches   Hope it helps

This is extension of answer provided by Ranjith  I would suggest  you to choose a choice-parameter build  and specify the branches that you would like to build  Active Choice Parameter  And after that  you can specify branches to build  Branch to Build  Now  when you would build your project  you would be provided with  Build with Parameters  where you can choose the branch to build   You can also write a groovy script to fetch all your branches to in active choice parameter

I can see many good answers to the question  but I still would like to share this method  by using Git parameter as follows   When building the pipeline you will be asked to choose the branch   After that through the groovy code you could specify the branch you want to clone  git branch BRANCH 7  -1   url   https   github com YourName YourRepo git    credentialsId   github    Note that I m using a slice from 7 to the last character to shrink  quot origin  quot  and get the branch name  Also in case you configured a webhooks trigger it still work and it will take the default branch you specified master in our case

Best solution can be   Add a string parameter in the existing job   Then in the Source Code Management section update Branches to build to use the string parameter you defined   If you see a checkbox labeled Lightweight checkout  make sure it is unchecked   The configuration indicated in the images will tell the jenkins job to use master as the default branch  and for manual builds it will ask you to enter branch details  FYI  by default it s set to master
