在 当前仓库根目录下执行命令

git submodule add https://github.com/xxx/child.git

检查仓库状态

git status

更新子库

git submodule update --remote

下拉父仓库Git并保住子库也更新

git pull --recurse-submodules

推荐使用 Githubdesktop工具

这样你可以更清楚的看到自己子库关联状态

在Unity本使用脚本调用Git

public static void NewGitCommand( string arguments, string WorkingDirectory = "./" ){string gitPath = "git";ProcessStartInfo startInfo = new ProcessStartInfo( gitPath, arguments ){WindowStyle = ProcessWindowStyle.Hidden,UseShellExecute = false,ErrorDialog = false,CreateNoWindow = true,RedirectStandardError = true,RedirectStandardInput = true,RedirectStandardOutput = true,LoadUserProfile = true,WorkingDirectory = WorkingDirectory};var p = new Process { StartInfo = startInfo };p.OutputDataReceived += new DataReceivedEventHandler( ( object sender, DataReceivedEventArgs eventArgs ) =>{if ( !string.IsNullOrEmpty( eventArgs.Data ) ){Debug.Log(eventArgs.Data);}} );p.ErrorDataReceived += new DataReceivedEventHandler( ( object sender, DataReceivedEventArgs eventArgs ) =>{if ( !string.IsNullOrEmpty( eventArgs.Data ) ){Debug.Log( eventArgs.Data );}} );p.Start();p.BeginOutputReadLine();p.WaitForExit();p.Close();p.Dispose(); }

案例

   public static void InitOrUpdateSubmodule(){//Log.PINK( "Begin Update Submodule ======>" );NewGitCommand( "submodule update --init --recursive" );NewGitCommand( "pull" );NewGitCommand( "submodule update" );NewGitCommand( "submodule update --remote" );AssetDatabase.Refresh();//Log.PINK( "End Update Submodule ======>" );}
