github personal access token
fork了一份unreal源码，想用sourcetree clone到本地，但提示“这是一个无效路径/URL”，点详细，看到报错信息：
命令: git -c diff.mnemonicprefix=false -c core.quotepath=false --no-optional-locks ls-remote https://github.com/wantnon/UnrealEngine-Yang
输出:
错误: remote: Support for password authentication was removed on August 13, 2021.
remote: Please see https://docs.github.com/en/get-started/getting-started-with-git/about-remote-repositories#cloning-with-https-urls for information on currently recommended modes of authentication.
fatal: Authentication failed for 'https://github.com/wantnon/UnrealEngine-Yang/'
命令: hg identify extensions.hgext.hgsubversion=! https://github.com/wantnon/UnrealEngine-Yang
输出:
错误: abort: HTTP Error 404: Not Found
命令: perl.exe C:\Users\admin\AppData\Local\SourceTree\app-3.4.15\tools\svn.pl info https://github.com/wantnon/UnrealEngine-Yang

gpt回答：
即是说，从报错信息看，这个仓库需要使用personal access token访问才行，并给出了git命令写法：
git -c diff.mnemonicprefix=false -c core.quotepath=false --no-optional-locks ls-remote https://<your-username>:<personal-access-token>@github.com/<your-username>/<repository>.git
所以解法如下：
1，source登录github：
2，github页面上申请personal access token：
github页面settings->developer settings，创建一个名为myCommonToken的token：
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（注：此token现已失效）
token设置如下：（all repositories+权限全开）
3，运行命令行：
在sourcetree命令行中运行命令：
git -c diff.mnemonicprefix=false -c core.quotepath=false --no-optional-locks ls-remote https://wantnon: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@github.com/wantnon/UnrealEngine-Yang.git
可见，成功列出了仓库中文件，说明访问成功了。
接下来clone。
切换目录：
clone：
git clone https://wantnon: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@github.com/wantnon/UnrealEngine-Yang.git
clone成功。
然后把clone到本地的仓库添加到sourcetree即可：
