How to change string from variable in yml file?

Question

I have a yml file used by an Azure pipeline for configuration.

variables: 
    CHANGE_URL :   $(System.PullRequest.SourceRepositoryURI)/pull/$(System.PullRequest.PullRequestNumber)   

The resulting variable CHANGE_URL is: https://github.com/username/project-boilerplate.git/9

The values are coming from Azure's predefined system variables. I'm trying to remove the '.git' from this string. I tried

CHANGE_URL : sed 's/...$//' <<< $(System.PullRequest.SourceRepositoryURI) but that did not work. I'm not sure how much control I have with yml files.

Answer 1

you need to have a script step that does that:

- bash: |
    value=$(sed 's/...$//' <<< $(System.PullRequest.SourceRepositoryURI))
    echo "##vso[task.setvariable variable=CHANGE_URL]$value"

and then in your subsequent steps you'd have a variable CHANGE_URL with the value you needed
