💡 Hint

Common Mistakes

Using 'develop' or other branch names instead of 'main'.

Forgetting to compare the branch name as a string.

The deployment should happen only on the 'main' branch, so the condition must check for 'main'.

Complete the code to skip deployment if the build is triggered by a pull request.

Jenkins

💡 Hint

Common Mistakes

Using empty string '' instead of null.

Using 0 or true which are not valid for this check.

When the build is not a pull request, CHANGE_ID is null. So to skip deployment on PRs, check if CHANGE_ID is not null.
