GitHub Actions If contains function not working with env.VARIABLE

[gomfucius]

I have setup an environment variable using:

echo "::set-env name=PROJECT_TO_TEST::$(sh scripts/test.sh)"

test.sh just echoes “SomeString, MoreString”

In a step right after, I’m doing a if check to see the PROJECT_TO_TEST variable contains ‘SomeString’ and a dummy ‘ShouldNotRun’ like so:

- name: Conditionally Run
  if: contains('${{ env.PROJECT_TO_TEST }}', 'SomeString')
  run: |
    echo "SomeString did exist and should run"
- name: Conditionally Run
  if: contains('${{ env.PROJECT_TO_TEST }}', 'ShouldNotRun')
  run: |
    echo "ShouldNotRun"

In this case, only the “SomeString did exist and should run” should get printed, but “ShouldNotRun” is also getting printed.

I had to remove the ${{}}, this works:

if: contains(env.PROJECT_TO_TEST, 'SomeString')

Yeah, you are right. According to this document - When you use expressions in an if conditional, you do not need to use the expression syntax (${{ }}) because GitHub automatically evaluates the if conditional as an expression.
