Jenkins:如何使用powershell检查Nexus中是否存在服务器目录？

pipeline {
    agent any
    
    stages {
        stage('Check Nexus Directory') {
            steps {
                powershell '''
                $url = "https://nexus.example.com/repository/my-repo/my-directory"
                $response = Invoke-WebRequest -Uri $url -Method Head
                
                if ($response.StatusCode -eq 200) {
                    Write-Host "Directory exists in Nexus."
                } else {
                    Write-Host "Directory does not exist in Nexus."
                }
                '''
            }
        }
    }
}
