错误：无法在jenkins输出控制台中更新svn repo

Question

嗨，我正在尝试使用jenkins构建项目。我正在使用jenkins管道，并且已在我的jenkinsfile中编写了此代码

node {
    stage('checkout')
    {
    checkout([$class: 'SubversionSCM', additionalCredentials: [], excludedCommitMessages: '', excludedRegions: '', excludedRevprop: '', excludedUsers: '', filterChangelog: false, ignoreDirPropChanges: false, includedRegions: '', locations: [[cancelProcessOnExternalsFail: true, credentialsId: '007bee40-b740-4f9f-99a4-f6b505163dd7', depthOption: 'infinity', ignoreExternalsOption: true, local: '.', remote: 'http://34.204.108.229/repos/newrep/branches']], quietOperation: true, workspaceUpdater: [$class: 'UpdateUpdater']])
    }

}

但是在构建它时出现此错误错误：无法更新http://34.204.108.229/repos/newrep/branches org.tmatesoft.svn.core.SVNException：svn：E200030：READONLY

任何帮助将不胜感激
