How to refer to a file in Azure Devops

Azure Devops is a necessary evil. I mean someone or something has to run my code, and I prefer it not being me.

Last week, I ran into the case where I had to pull up a config from a file and load it into my pipeline. I asked ChatGPT and this is what I was told to do.

To reference a specific file in Azure Devops, use the Build.SourcesDirectory variable that is available for each build.

Say we want to refer to the file models/active_models.json which is input for src/run.py like this:

$ tree
models
├── active_models.json
src
├── run.py

Then we can simply do this:

- task: AWSShellScript@1
  inputs:
    scriptType: 'inline'
    inlineScript: |
      python ./src/run.py --path $(Build.SourcesDirectory)/models/active_models.json
