如果以前的提交被重新纠正，管道将失败

Question

当将提交合并到主人身上时，我能够运行管道以检查是否需要重新重新进行，但是一旦将提交重新构成并与主分支同步，它将通过管道。我的脚本是比较合并完成后的两个父母所做的。如果将提交重新列入并将其合并到Bitbucket Master分支，则搜索使管道失败的方法。

我的脚本如下：

#!/bin/bash
trg=$1
itg=$2

parent_commit_count=$(git cat-file -p $BITBUCKET_COMMIT | grep -o -i parent | wc -l)
echo "Number of parent commits:"$parent_commit_count
if [ "${parent_commit_count}" = "2" ] 
then
echo "Validating master branch graph shape"
fi

if [[ -z $trg ]]; then
trg=HEAD
fi

if [[ -z $itg ]]; then
itg=master
fi

ret=$(git rev-list $trg..$itg)
if [[ -z $ret ]]; then
 echo "No rebase required, sexy graph is maintained."

else
    echo "Commit $BITBUCKET_COMMIT needs to be rebased to absorb the following changes:"
     for r in $ret
     do
     echo $r
     done
    exit 1
fi

branches:
    master:
      - step:
          name: Branch Trigger to Master
          script:
            - echo "Checking Merge Commit"
            - chmod +x MergeCommitCheck.sh && ./MergeCommitCheck.sh
