remote: ERROR: missing Change-Id in commit message footer
remote: Suggestion for commit message:

remote: Hint: To automatically insert Change-Id, install the hook:

 ! [remote rejected] HEAD -> refs/for/master (missing Change-Id in commit message footer)

error: failed to push some refs to 'ssh://gerrit@127.0.0.1:29418/demo-project'

执行完scp -p -P 29418 gerrit@127.0.0.1:hooks/commit-msg `git rev-parse --git-dir`/hooks/commit-msg之后没什么反应，再次提交还是不行

要在commit信息里面写上Change-Id才行

    Init commit
    
    Change-Id: Iacca76130d4b1d33bf234a9acc7f83bc8edf5bd9

这样才能提交
