如何在groovy Jenkinsfile中选择不同的git代码库(main和forked)来运行Jenkins2.0作业

pipeline {
    agent any
    
    stages {
        stage('Checkout') {
            steps {
                script {
                    if (env.BRANCH_NAME == 'main') {
                        git url: 'https://github.com/your-main-repo.git', branch: 'main'
                    } else if (env.BRANCH_NAME == 'forked') {
                        git url: 'https://github.com/your-forked-repo.git', branch: 'main'
                    } else {
                        error "Unsupported branch: ${env.BRANCH_NAME}"
                    }
                }
            }
        }
        
        // Add more stages for your Jenkins job
        
    }
}
