Problem

Starting 1st June 2023 (planned), GitHub Actions will not support ::set-output name...:: syntax cannot be used.

Solution

If the command in the workflow file is not complex, you can simply replace the old syntax with the new one using regex like this: echo "::set-output name=(.+?)::(.+?)" -> echo "$1=$2" >> \$GITHUB_OUTPUT

This regex will replace the command like this:

steps:
- run: echo "::set-output name=my-output-variable-key::value"

with

steps:
- run: echo "my-output-variable-key=value" >> $GITHUB_OUTPUT

The previous syntax was quite confusing at first. So while it requires a lot of work by developers around the world, it’s a good occasion to refactor it with the cleaner syntax! ✨
