git 错误：致命：模棱两可的参数"起源/主"。pipeline_creation'：未知修订版或路径不在工作树中

Question

我正在使用gitlab。我有一个运行git命令diff的yml文件。这个命令显示了两个分支之间的差异。下面是yml文件

image: bitnami/git:latest
stages:
- Test
Test_stage:
tags:
- docker
stage: Test
script:
- echo "test stage started"
- git diff --color=always origin/main..pipeline_creation README.md | perl -wlne 'print 
$1 if /^e[32m+e[me[32m(.*)e[m$/'

当我在管道中运行这个时，我得到这个错误:

Created fresh repository.
Checking out e33fa512 as pipeline_creation...
Skipping Git submodules setup
Executing "step_script" stage of the job script
00:00
$ echo "test stage started"
test stage started
$ git branch -a
* (HEAD detached at e33fa51)
remotes/origin/pipeline_creation
$ git diff main..pipeline_creation README.md
fatal: ambiguous argument 'main..pipeline_creation': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'

本地命令工作正常，但当我在管道中运行它时，它没有显示预期的结果。有人知道我做错了什么吗?

git branch -a的输出显示了问题的原因:repo没有任何本地分支，只有一个远程分支remotes/origin/pipeline_creation。您需要先获取main分支，然后才能在git diff命令中使用它:

git fetch --depth=1 origin main
