Defining Conditional Steps

[Sascha Mowtschan]

I want to run some steps only in particular cases.

My expectation would be like:

- step:
   name: some conditional step
   script:
     - echo "run only if the condition is true"
   when: <some condition>

Hi @Sascha Mowtschan

We don't have such configuration to set special conditions for a build to happen. 
Would you mind sharing what type of conditions you would test in the when clause?
Depending on what you share for those conditions I'll be able to open a feature request for this.

If you are attempting to avoid builds on certain commits you can use the "[skip ci]" token in their commit message. Commits with that token will not trigger builds.

• Reference: Bitbucket Pipelines FAQ - Atlassian Documentation (Section: Can I commit without triggering the pipeline?).

Hi @Daniel Santos 

something like:

when: $(git diff --name-only --diff-filter=AMDR HEAD^ some-directory-or-file) != ""

Hi @Sascha Mowtschan

I've created the following feature request for this:

Please vote on this one and add yourself as a watcher to make sure you will have any updates from that ticket. Let me know if you have more comments or questions on this matter. =]

I voted and added my self as a watcher.

- step:
          name: path1 failing step
          script:
             - echo "failing path1"
             - exit 1
          condition:
              changesets:
                 includePaths:
                   - "path1/*"
                   - "path2/*"

Hi @Alex Popa

Could you please share me the documents or more configuration for this condition step?

Many thanks,

NAT

@NAT search for "condition", because BB pipeline documentation sucks https://support.atlassian.com/bitbucket-cloud/docs/configure-bitbucket-pipelinesyml/

At the moment, using exactly the syntax specified in the documentation results in an error that the yaml file is failing schema validation.  It says 

There is an error in your bitbucket-pipelines.yml at [pipelines > branches > master > 0 > step > condition]. 
To be precise: At least one condition is required

My step is defined as:

 - step: &codegen
     name: Generate Protos
     script:
       - make ci_tools
       - make proto_go
     artifacts:
       - golang/**
     condition:
       changesets:
         includePaths:
           - "proto/**/*.proto"
