Jobs inside stages not executing in parallel

[cryptox31]

I have tried various configurations inside stages but I am unable to make travis execute jobs in parallel inside stages.

I have gone through these links:

• https://docs.travis-ci.com/user/build-stages/
• https://docs.travis-ci.com/user/build-stages/using-yaml-aliases/ (test staging part)
  and I have still not gotten it(stage FVT) to work in parallel

This one snippet of the travis yaml

dist: trusty
language: java
sudo: true
group: bluezone
jdk: openjdk11
services:
  - docker

branches:
  only:
    - develop

before_cache:
  - rm -f  $HOME/.gradle/caches/modules-2/modules-2.lock
  - rm -fr $HOME/.gradle/caches/*/plugin-resolution/
cache:
  apt: true
  directories:
    - $HOME/.gradle/caches
    - $HOME/.gradle/wrapper
    - $HOME/.cache/pip
install:
  # Install Ansible.
  - sudo apt-get update
  - sudo apt-get install python3
  - sudo -H pip install --upgrade pip
  - sudo -H pip install ansible
  - sudo apt-get install sshpass

jobs:
  include:
    - stage: "Build and Deploy"
      script: ./playbooks/dev/deploy_image.sh
    - &fvt
      stage: test
      script: ./qa/src/test/resources/test1.sh
    - <<: *fvt
      script: ./qa/src/test/resources/test2.sh

and this is another snippet (The section above jobs.include is not pasted as it is same as the 1st snippet):

jobs:
  include:
    - stage: "Build and Deploy"
      script: 
      - ./playbooks/dev/deploy_image.sh
    - stage: "FVT"
      name: "A"
      script:
      - ./qa/src/test/resources/test1.sh
    - stage: "FVT"
      name: "B"
      script:
      - ./qa/src/test/resources/test2.sh

When reporting problems, please consider including:

1. What you are trying to achieve
2. What you have tried (probably a link to the configuration)
3. What happened instead (often, pointing to a build log URL, in the form of https://travis-ci.com/OWNER/REPO/build/NNNNNNN would be helpful).

The title itself says that jobs are not executing in parallel.

Unfortunately, I cannot link the travis repo here because it’s a private repo.

Do you know what are the possible reasons for the jobs inside stages not executing in parallel?

[BanzaiMan]

They could be queued simultaneously, but one of them could be held in the queue for a few different reasons. Your organization might be running too many jobs, and your repo might have a limit on the number of concurrent jobs. Without concrete information, we cannot really help you. If you wish to discuss it in private, please email support@travis-ci.com.

So, I figured what the problem was.

I changed the concurrent build setting to two and parallel jobs inside stages started working

but this caused a side effect to our builds because our builds depend on external servers to test the build we deploy to.

Is there a way to only allow parallel builds inside stages and limit to 1 concurrent build?

@BanzaiMan Any updates?

@cryptox31

Is there a way to only allow parallel builds inside stages and limit to 1 concurrent build?

Then there is no need to have these in the same stage. Just separate them into different stages. “Build 1”, “Build 2”, “Build 3”, etc.
