无法将所有perforce分支导入git repo

|| 我正在尝试从公司的Perforce软件仓库将项目导入git存储库。我已经成功地将单个分支添加到了一个git仓库中,但是我想做的是引入整个项目以及所有分支,但是我无法使其正常工作。 我有我的.p4settings文件:
P4PORT=perforce-server.local:1666
P4USER=my.username
P4CLIENT=my.clientspec.name
Clientspec非常简单:
//project/... //my.clientspec.name/project/...
-//project/External/... //my.clientspec.name/project/External/...
第二行是将外部库二进制文件从检出中排除。 我使用以下命令行开始git-p4导入:
git p4 clone --verbose --detect-branches --max-changes=100 //project/...@all
这将进行检查所有分支名称等,并尝试从第一个提交开始导入(此特定项目从变更列表771开始)
Importing from //project/...@all into project
Initialized empty Git repository in /Users/grant/Development/git_test/project/.git/
Reading pipe: git config git-p4.useclientspec
Reading pipe: git config git-p4.user
Reading pipe: git config git-p4.password
Reading pipe: git config git-p4.port
Reading pipe: git config git-p4.host
Reading pipe: git config git-p4.client
p4 -G branches
Opening pipe: p4 -G branches
p4 -G branch -o branch-1
Opening pipe: p4 -G branch -o branch-1
Reading pipe: git config --bool core.ignorecase
p4 -G branch -o branch-2
...
Opening pipe: p4 -G branch -o branch-n
p4-git branches: []
initial parents: {}
我不确定p4-git是否分支,并且最初的父母在这里应该是空的,但是确实如此。 最终,我们将开始将变更列表导入git并发生以下情况:
Getting p4 changes for //project/...
p4 changes //project/...
Reading pipe: p4 changes //project/...
p4 -G describe 771
Opening pipe: p4 -G describe 771
Importing revision 771 (1%)branch is MAIN

    Importing new branch RCMerge/MAIN

现在,作为perforce的新手,我不知道这意味着什么,也不知道如何解决此问题,甚至不知道是否可能解决。有人遇到过类似的问题吗?如果是这样,您如何解决?

我终于找到了解决这个问题的方法。事实证明,Perforce分支映射是反向完成的,这就是此问题的根源。 Branch-foo是从MAIN分支出来的,MAIN应该具有如下的分支映射:
//project/MAIN/... //project/Branch-foo/...
但是,创建分支的人反转了映射,因此导致:
//project/Branch-foo/... //project/MAIN/...
这让git-p4感到困惑,因为MAIN的第一个更改列表从#771开始,而Branch-foo的更改列表从#7652开始,因此它在Branch-foo中找不到任何父项并崩溃了。将分支规范更改为上面列出的第一个规范可以解决问题。
