開始 try 的：
variables:
f1Flag: false
f2Flag: false
trigger:
branches:
include:
- master
# paths:
# include:
# - "test_pipelines/*"
steps:
- powershell: |
## get the changed files
$files=$(git diff-tree --no-commit-id --name-only -r $(Build.SourceVersion))
$temp=$files -split ' '
$count=$temp.Length
echo "Total changed $count files"
For ($i=0; $i -lt $temp.Length; $i++)
{
$name=$temp[$i]
echo "this is $name file"
if ($name -like 'test_pipelines/*') #if test_pipelines is a subfolder under a folder use "- like '*/f1/*'"
{
##set the flag variable f1Flag to true
Write-Host "##vso[task.setvariable variable=f1Flag]true"
}
}
- script: echo $(f1Flag)
