我对CI/CD概念相对陌生。
我正在尝试使用Jenkins中的声明性管道(没有SCM(克隆Github存储库。
如果我在没有任何凭据的情况下这样做，那么我可以在控制台输出中看到Jenkins已经在尝试克隆该repo，但这需要非常长的时间。我已经可以看到，在Jenkins工作区中，我有一个名为github repo的文件夹，但里面只有一个.git文件夹，它需要很长时间，但从未提取repo。在互联网上搜索后，我发现访问存储库的权限不见了。
然后我在Jenkins中添加了Github repo的凭据。我有以下脚本。
pipeline {
agent any
stages {
stage('clone repo') {
steps {
withCredentials(usernamePassword(credentialsId :jenkins-user-github ,passwordVariable: 'GIT_PASSWORD', usernameVariable: 'GIT_USERNAME' )){
// Get some code from a GitHub repository
bat("""
git config --global credential.username {GIT_USERNAME}
git config --global credential.helper "!echo password={GIT_PASSWORD}; echo"
git clone https://github.com/aakashsehgal/FMU.git
echo "pulled the code"
""")
}
}
}
}
}
但我得到以下错误：

知道我在这里错过了什么吗？
在后台使用用户名和密码时，会出现语法问题。您应该使用${GIT_USERNAME}，而不是仅使用{GIT_USERNAME}。
话虽如此，您需要明确提到您需要签出的分支。我想默认情况下您会希望签出到master分支。因此，请使用以下内容：
pipeline {
agent any
stages {
stage('Checkout') {
steps {
script {
// The below will clone your repo and will be checked out to master branch by default.
git credentialsId: 'jenkins-user-github', url: 'https://github.com/aakashsehgal/FMU.git'
// Do a ls -lart to view all the files are cloned. It will be clonned. This is just for you to be sure about it.
sh "ls -lart ./*"
// List all branches in your repo.
sh "git branch -a"
// Checkout to a specific branch in your repo.
sh "git checkout branchname"
}
}
}
}
}
如果您想在默认情况下签出到特定的分支，请在管道阶段使用以下内容。使用以下部分，您将不需要单独运行git checkout命令。
pipeline {
agent any
stages {
stage('Checkout') {
steps {
checkout([$class: 'GitSCM', branches: [[name: '*/branchname']], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: 'jenkins-user-github', url: 'https://github.com/aakashsehgal/FMU.git']]])
sh "ls -lart ./*"
}
}
}
}
