在Jenkins管道中使用凭证签出SVN？

Question

如何通过Jenkins管道groovy脚本检出需要用户凭据的Subversion存储库？似乎内置svn命令不支持凭据，因此我尝试了如下代码：

node {
    stage 'checkout'
    withCredentials([[$class: 'UsernamePasswordMultiBinding',
                      credentialsId: '34761a89-1402-47d7-96e2-aec22ffdc50b',
                      usernameVariable: 'USERNAME', passwordVariable: 'PASSWORD']]) {
        sh "svn co https://trac.nci.org.au/svn/cable/branches/$SVN_BRANCH --username $USERNAME --password $PASSWORD cable_branch"
    }
}

但这失败了

groovy.lang.MissingPropertyException: No such property: USERNAME for class: groovy.lang.Binding
    at groovy.lang.Binding.getVariable(Binding.java:63)
    at org.jenkinsci.plugins.scriptsecurity.sandbox.groovy.SandboxInterceptor.onGetProperty(SandboxInterceptor.java:224)
    at org.kohsuke.groovy.sandbox.impl.Checker$4.call(Checker.java:241)

    at ___cps.transform___(Native Method)
    ...

我想念什么？

您可以将 代码片段生成器 用于 常规SCM 步骤。这将显示熟悉的Subversion配置选项，并照常将凭据作为参数。

代码段生成器会产生一些难看的参数选择表示，如下所示：

checkout([$class: 'SubversionSCM', 
          additionalCredentials: [], 
          excludedCommitMessages: '', 
          excludedRegions: '', 
          excludedRevprop: '', 
          excludedUsers: '', 
          filterChangelog: false, 
          ignoreDirPropChanges: false, 
          includedRegions: '', 
          locations: [[credentialsId: '34761a89-1402-47d7-96e2-aec22ffdc50b', 
                       depthOption: 'infinity', 
                       ignoreExternalsOption: true, 
                       local: 'cable_branch', 
                       remote: "https://trac.nci.org.au/svn/cable/branches/$SVN_BRANCH"]], 
          workspaceUpdater: [$class: 'UpdateUpdater']])

注意， 远程 部分使用双引号，因此变量$ SVN_BRANCH被正确替换。
