Azure DevOps Pipeline - list all Build SourceBranches - azure

Question

This is my simple pipeline,
# Starter pipeline
# Start with a minimal pipeline that you can customize to build and deploy your code.
# Add steps that build, run tests, deploy, and more:
# https://aka.ms/yaml
pool:
name: LinuxJavaCIBuildAgents #CheckmarxAgents #LinuxJavaCIBuildAgents
workspace:
clean: all
resources:
repositories:
- repository: repo_a
type: git
name: InternalProjects/repo_a
trigger:
- main
- release
- repository: repo_b
type: git
name: InternalProjects/repo_b
trigger:
- main
- release
steps:
- task: Bash#3
inputs:
targetType: 'inline'
script: echo ....??? what to echo to list all repositories and their source branch from resources.repositories
How do I list all Build SourceBranches that are involved in the above build pipeline? we have 2 repos: repo_a and repo_b, I want to list them using bash and list their source branches.
Thanks

Azure DevOps supports multiple repositories check out as a built-in function, Refer to the YAML code below:-
# Starter pipeline
# Start with a minimal pipeline that you can customize to build and deploy your code.
# Add steps that build, run tests, deploy, and more:
# https://aka.ms/yaml
pool:
vmImage: ubuntu-latest
workspace:
clean: all
resources:
repositories:
- repository: repo_a
type: git
name: InternalProjects/repo_a
ref: main
trigger:
- main
- release
- repository: repo_b
type: git
name: InternalProjects/repo_b
ref: main
trigger:
- main
- release
steps:
- checkout: repo_a
- checkout: repo_b
- script: dir $(Build.SourcesDirectory)
While running the pipeline it will ask for authorization to allow both the repositories to run like below:-
After granting the permission:-
To list the build source branches of the above repos you can use the below echo command as a Bash Inline script in your YAML code:-
# Starter pipeline
# Start with a minimal pipeline that you can customize to build and deploy your code.
# Add steps that build, run tests, deploy, and more:
# https://aka.ms/yaml
pool:
vmImage: ubuntu-latest
workspace:
clean: all
resources:
repositories:
- repository: repo_a
type: git
name: InternalProjects/repo_a
trigger:
- main
- release
- repository: repo_b
type: git
name: InternalProjects/repo_b
trigger:
- main
- release
steps:
- task: Bash#3
inputs:
targetType: 'inline'
script: |
#!/bin/bash
echo
for repo in $(echo $(echo "${resources}" | jq -r '.repositories[].name')); do
echo "Repository: $repo"
echo "Source branches: $(echo "${resources}" | jq -r '.repositories[] | select(.name == "$repo") | .trigger[]')"
echo "Source branches"
done
Pipeline Run:-
If you want to make sure all repos run on the same branch and require a warning if another repo runs on a different branch, Use below YAML code:-
# Starter pipeline
# Start with a minimal pipeline that you can customize to build and deploy your code.
# Add steps that build, run tests, deploy, and more:
# https://aka.ms/yaml
pool:
vmImage: ubuntu-latest
workspace:
clean: all
resources:
repositories:
- repository: repo_a
type: git
name: InternalProjects/repo_a
trigger:
- main
- release
- repository: repo_b
type: git
name: InternalProjects/repo_b
trigger:
- main
steps:
- task: Bash#3
inputs:
targetType: 'inline'
script: |
#!/bin/bash
# Get the source branch of the first repository
source_branch=$(echo "${resources}" | jq -r '.repositories[0].trigger[]')
# Loop through the other repositories and compare the source branch with the first repository
for repo in $(echo $(echo "${resources}" | jq -r '.repositories[].name' | tail -n +2)); do
if [[ $(echo "${resources}" | jq -r '.repositories[] | select(.name == "$repo") | .trigger[]') != "$source_branch" ]]; then
echo "Error: Repository $repo is running on a different branch ($(echo "${resources}" | jq -r '.repositories[] | select(.name == "$repo") | .trigger[]')) than the first repository ($source_branch)"
exit 1
fi
done
echo "All repositories are set to run on branch $source_branch"
