A common pattern for developing libraries and frameworks is to run the same tests against multiple versions of a language or frameworks. A great example is the rails pipeline:

But we don't have any ready examples of how to do this. It'd be great to have an example pipeline to point to!

Be neat to have a Python example…

# Install virtualenvwrapper on the system
pip install virtualenvwrapper

# From an env hook
export WORKON_HOME=~/Envs
source /usr/local/bin/virtualenvwrapper.sh
mkvirtualenv .
workon .

Hi, you can see my step, I want to skip the command when if the result is true.

`steps:

• label: ":maven: :package:"
  command: mvn package
  if: build.tag == "v1.0"
  artifact_paths: "target/*.jar"
  plugins:

  • docker-compose#v1.5.2:
    run: maven
    config: .buildkite/docker-compose.yml

• wait

• label: "Deploy"
  command: "deploy.sh"
  if: build.tag == "v1.0"`

but when I add the tag v1.0 and push the code, I found all command will not be work through. can you help me?
