Exclude jobs based on branch name

[lmazuel]

Hello,

I'm sorry if this topic is covered somewhere in the documentation, I wasn't able to find an answer anywhere.

I want to exclude jobs from my matrix depending of the branch name.
For instance, let's say I have two Python jobs:

language: python
python:
  - "2.7"
  - "3.6"

I want to exclude "2.7" if branch names startswith "deploy", but do everything if not ("master", PRs, etc.).

Deployment framework already allows me to deploy only if "python" is "3.6", but the other job are still executed (for nothing, waste of time and resources).

I was looking for a way to declare that in "exclude" of "matrics" (of anywhere else to achieve the goal :))

Workaround tentative: is there a way to skip a job from a before_install step (so I can check $TRAVIS_TAG and exit)?

Thank you!

matrix:
  - python: "3.6"
  - python: "2.7"
    before_install:
      - if ! [[ $TRAVIS_TAG ]]; then exit 0; fi

works to bail out early, but you still need to wait for the machine to be provisioned and the setup that happens before_install

This feature is useful for Build Stages.

Same requirement over here. We are building an Android .apk on a - language: android matrix and it takes several minutes for the environment to boot and startup before bailing thanks to - if [ -z "$TRAVIS_TAG" ]; then travis_terminate 0; fi;.

It'd be nice if it could be skipped altogether. Something like an on: clause for every include in the matrix, perhaps?

This feature is super useful for partial builds.

Same issue on our side. The "deploy" job still has to boot up and run even for PR builds where we definitely do not want to deploy code.

feature was already approved , more info at travis-ci/beta-features#11

While it is considered beta (some future changes are possible), our recent release of the Build Stages feature makes this possible. https://blog.travis-ci.com/2017-09-12-build-stages-order-and-conditions

In the use case of OP:

I want to exclude "2.7" if branch names startswith "deploy", but do everything if not ("master", PRs, etc.).

One can write:

language: python
python:
  - "3.6"
matrix:
  include:
    - python: "2.7"
      if: branch =~ ^deploy

@BanzaiMan I had success with your suggestion by flipping the order of the if

language: python
python:
  - "3.6"
matrix:
  include:
    - if: branch =~ ^deploy
      python: "2.7"
