Trying to retrieve latest commit in main branch before the new head.
But using CI_COMMIT_BEFORE_SHA its returning always zero's. In case, if I run pipeline from the GitLab UI.
It working fine if its trigged automatically in case of a push to main branch.
Pipline Custome Variables using Predefined Gitlab CI variables:--
Check if this is related to issue 12850 "CI_COMMIT_BEFORE_SHA is all zero in a merge request pipeline".
Or issue 28252 "Expose CI_MERGE_REQUEST_SOURCE_BRANCH_SHA and CI_MERGE_REQUEST_TARGET_BRANCH_SHA in detached merge request pipelines"
Try a simple test to see if that would work better with your current version of GitLab:
image: node:8
test-ci-vars:
only:
- master
- merge_requests
script:
- echo CI_COMMIT_REF_NAME=${CI_COMMIT_REF_NAME}
- echo CI_MERGE_REQUEST_SOURCE_BRANCH_SHA=${CI_MERGE_REQUEST_SOURCE_BRANCH_SHA}
- echo CI_MERGE_REQUEST_TARGET_BRANCH_SHA=${CI_MERGE_REQUEST_TARGET_BRANCH_SHA}
- echo CI_MERGE_REQUEST_SOURCE_BRANCH_NAME=${CI_MERGE_REQUEST_SOURCE_BRANCH_NAME}
- echo CI_MERGE_REQUEST_TARGET_BRANCH_NAME=${CI_MERGE_REQUEST_TARGET_BRANCH_NAME}
