这解决了我的问题。

   git pull https://myusername:mypassword@github.com/path_to/myRepo.git

我的代码片段:

environment {
    ...
    ...
    git_repo = 'my-repo'
}

stage ('Update Helm Chart') {
    steps {
        echo 'Updating values.xml file with latest Docker image tag'

        withCredentials([usernamePassword(credentialsId: '6bgg7dd45-c65f13-4275-a96ddehdv67gdr', usernameVariable: 'GIT_USER', passwordVariable: 'GIT_PASS')]) {
            sh '''
                git checkout ${git_branch}
                ...
                ...
                git remote set-url origin "http://${GIT_USER}:${GIT_PASS}@git.example.com/scm/${git_repo}.git"
                git push origin ${git_branch}
            '''
        }
    }
}

我的Git用户名是deploy.user@example.com，所以我必须首先URL编码@ %40。在URL编码之后，我的用户名变成了deploy.user%40example.com。

然而，我仍然得到以下错误:

fatal: repository 'http://****:****@git.example.com/scm/my-repo.git/' not found

经过一些试验和错误，我发现，如果我不使用变量的用户名，而是硬编码它，它的工作。

git remote set-url origin "http://deploy.user%40example.com:${GIT_PASS}@git.example.com/scm/${git_repo}.git"

如果有人在github.com上遇到这个问题，检查你是否接受了回购所有者允许提交给你的邀请。直到你接受邀请，回购将是无形的为您。所以你会得到ERROR: Repository not found。

Normally it happens because the project is private and you have not rights to write it. I had the same "problem" a few times, and it was for that reason. If the project it is yours, just create a private and a public key following this link: https://docs.github.com/en/github/authenticating-to-github/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent and add them to the "SSH and Key" section on gitHub, then you will be able to push to the repo. In the other hand if the project it is not your, ask the owner to give you the rights for it.

在执行此操作之前，请确保您拥有对回购的写权限。如果您仍然得到错误，请执行以下操作:

Generate a personal access token from your account from Settings > Developer Settings > Personal Access tokens. Keep the token safe somewhere. Go to your repository and run the following: git remote rm origin Then add a new origin along with your username: git remote add origin https://USERNAME@github.com/REPOSITORY_LINK.git Now when you push the code, a prompt will show up asking for your password or personal access token. Paste the token that we generated in the first step in the field, and we're done.

当我试图推到我以前访问过的私人回购时，我遇到了这个错误。问题不在于回购是私有的还是公共的，问题在于Github API现在使用个人令牌而不是用户名和密码进行身份验证和授权。

以下方法解决了我的问题:

删除远程原点:git远程删除原点 生成一个个人代币:你可以在Github Docs中找到说明。 重新添加原点，但使用您的用户名和生成的令牌:

git远程添加origin https://USERNAME:GENERATED_TOKEN@github.com/username/reponame.git

注意: 如果在创建和使用令牌一段时间后遇到此问题，请确保令牌没有过期。如果是，重新生成它，并确保对使用旧令牌的回购重复第3步(如上所述)。此外，如果您更改了令牌，请为使用旧令牌的repo重做步骤3。
