我刚开始学习groovy，我想将svnSourcePath和svnDestPath传递给svn copy命令中的shell脚本。但是网址未呈现。

node {
 stage 'Copy Svn code'

def svnSourcePath = "${svnBaseURL}${svnAppCode}${svnEnvDev}${SVN_DEV_PACKAGE}"
def svnDestPath = "${svnBaseURL}${svnAppCode}${svnEnvTest}${SVN_DEV_PACKAGE}"

print "DEBUG: svnSourcePath = ${svnSourcePath}"
print "DEBUG: svnDestPath = ${svnDestPath}"

withCredentials([[$class: 'UsernamePasswordMultiBinding', credentialsId: crendentialsIdSVN, passwordVariable: 'SVN_PWD', usernameVariable: 'SVN_USER']]) {
    sh '''  
    svn copy $svnSourcePath $svnDestPath -m 'promote dev to test' --username $SVN_USER --password $SVN_PWD '''
}  
}

输出量

+ svn copy -m 'promote dev to test' --username techuser --password 'xxxyyy' 
     svn: E205001: Try 'svn help' for more info
