If I do ``` jobs: exclude: - if: 1 = 1 os: linux ``` in a .travis.yml file, Travis does Linux builds. If, however, I do ``` jobs: exclude: - os: linux ``` What I’m trying to do is to suppress most builds if the branch is coverity\_scan, but nothing I tried worked. What must I do here? ---

And I did ``` - gem install travis-conditions ``` in `before_install`. ---

Could you link to build(s) showcasing the problem? Just an excerpt is not enough for diagnostics, it can very well be something else entirely. ---

[This tcpdump build](https://travis-ci.org/github/the-tcpdump-group/tcpdump/builds/686926320) was the one where I first tried this. In [this commit](https://github.com/the-tcpdump-group/tcpdump/commit/5fd77bf58db4a16ec3989decc50cf18b2fef30f8) I tried suppressing Coverity builds by adding entries like ``` - arch: ppc64le if: branch == coverity_scan ``` to the ``` jobs: exclude: - arch: ppc64le os: osx - arch: s390x os: osx - arch: arm64 os: osx - compiler: gcc os: osx ``` section of .travis.yml to suppress ppc64, s390x, and arm64 coverity\_scan builds, because 1) they shouldn’t be necessary (AMD64 builds should suffice) and 2) they got stuck and reported errors. As that build indicates, it did not suppress the build. I tried several other things; in [this build](https://travis-ci.org/github/the-tcpdump-group/tcpdump/builds/686962013) [I tried just doing](https://github.com/the-tcpdump-group/tcpdump/commit/74941cf9d060745f77a900863a104ca05f21ba3f) ``` jobs: exclude: - if: 1 = 1 ``` as I inferred it should simply suppress _all_ builds; again, it did not. ---

**Please enable build config validation, or run your config through [https://config.travis-ci.com/explore.](https://config.travis-ci.com/explore.)** I forked your project and I have it enabled, and [immediately got an error from it](https://travis-ci.org/github/native-api/tcpdump/builds/687224760/config): > `root` : both `matrix` and `jobs` given, `matrix` overwrites `jobs` So your `jobs:` clause with the excludes is being ignored. Indeed, when I commented out `matrix:`, [jobs were excluded as expected](https://travis-ci.org/github/native-api/tcpdump/builds/687226138). `matrix:` is now an alias to `jobs:`, so just merge them under the latter name. ---

OK, we now have ``` jobs: fast_finish: true exclude: - arch: ppc64le os: osx - arch: s390x os: osx - arch: arm64 os: osx - compiler: gcc os: osx - if: branch = coverity_scan arch: ppc64le - if: branch = coverity_scan arch: s390x - if: branch = coverity_scan arch: arm64 cache: ccache env: global: # encrypted COVERITY_SCAN_TOKEN from # https://scan.coverity.com/projects//submit_build?tab=travis_ci - secure: "DwUeukcRGl1vXNZDDt2237zCA58ZzmzWpCkPcb/Hpeh8OvRw1eBZJiu4L8iD2qtY4A/dPDvOeBiml5MF6bVri9Dui1yPkvkvFqIXzbK5CWS6Ye+NgSBNMwqnAjhTMv/x8I4Bvy9IhDGwj/2JXVUvjBddRMLRyr/ag+MDRB1IVAI=" # Coverity run condition (avoid matrix multiple runs), need customized # build script.

Running [https://travis-ci.org/github/the-tcpdump-group/tcpdump/builds/689209239/config](https://travis-ci.org/github/the-tcpdump-group/tcpdump/builds/689209239/config) through [https://config.travis-ci.com/explore](https://config.travis-ci.com/explore), I’m not getting any `ppc64le` jobs. But they are in the actual build – which is supposed to be using the same expansion logic. This does seem to be a bug.
