Hello,

I have following requirements:

1. I want several Jobs for a Project with multiple Branches (or even Repositories)

• Integration: Build everything (with flags for faster compilation), don`t archive anything
• Staging: Allow a set of Parameters to control the build (what & how), Archive the output files. Usefull for building feature Branches for testing and verifying bug fixes.
• Release: Build the release artifacts with release settings. Archive release artifacts and sources

1. Changelogs are preserved for branches.
2. Incremential Builds should be possible

To solve this, I would need to create 3 multibranch jobs for the same sources - and a way to differenciate between them
I could work with job names (eg. adding .staging to the name) and parse the name in the scripts, but I `d prefer a better solution.

Some possibilities are:

• Allow defining Env Parameters for Multi-Branch jobs.
• Allow defining the script (and its repository) similar to the pipeline jobs.

1) would allow me to pick the right buildscript depending on a variable, and the parameters for the staging build could be seeded and optionally replaced by the pipeline scripts per-branch-job.
2) would allow to directly specify the build-script (no extra script for parsing env variables needed)
