instead full form like within branch driven pipeline

pipelines:

Expected:

Always return full form.

Workaround

Add the following command in your script, prior to using the BITBUCKET_COMMIT variable.

- export BITBUCKET_COMMIT=$(git log -1 --format="%H" $BITBUCKET_COMMIT 2>/dev/null)
- echo $BITBUCKET_COMMIT

BITBUCKET_COMMIT will then return the full hash.
