Jenkins error :54: expecting anything but ''\n''; got it anyway

Question

我在 jenkins 管道中使用以下 apache groovy 脚本将我的工件 (dev.ear) 部署到服务器。我在 groovy 中嵌入了 shell 脚本，以安全地将 dev.ear 从 jenkins slave 复制到目标服务器（unix 服务器）。

node('linux') {
    stage('Checkout/Download/Deploy') {
        timeout(time: 30, unit: 'MINUTES') {

        def ziptmp = '.ziptmp'
        output = sh returnStdout: true, script:"/bin/rm -rf ${ziptmp}; /bin/mkdir ${ziptmp}; cd ${ziptmp}; /usr/bin/unzip -qq ${tempdir}/${artifactFilename}; ls -ltr; echo *; 
            if [ -e dev.ear ]
            then
                scp dev.ear lsfi@${serverName57}:/apps/wls/dev/applications;
                echo "COPIED DEV ARTIFACT TO SERVER"

            else
                echo "DEPLOYMENT PACKAGE DOESNT CONTAIN DEV ARTIFACT"
            fi"
        echo "RESULT::: ${output}"
        }
    }
}

触发 Jenkins 作业时出现以下错误

WorkflowScript: 54: expecting anything but ''\n''; got it anyway @ line 54, column 171.
   ctFilename}; ls -ltr; echo *;

我删除了 shell 脚本中的新行并更新了如下代码：

def ziptmp = '.ziptmp'
output = sh returnStdout: true, script:"/bin/rm -rf ${ziptmp}; /bin/mkdir ${ziptmp}; cd ${ziptmp}; /usr/bin/unzip -qq ${tempdir}/${artifactFilename}; ls -ltr; echo *; if [ -e dev.ear ] then scp dev.ear lsfi@${serverName57}:/apps/wls/dev/applications; fi;"
echo "RESULT::: ${output}"

但我收到以下错误：

line 2: syntax error near unexpected token `fi'

如何解决这个错误。

Answer 1

Groovy 不喜欢 GString 中的换行符。根据 the Grails cookbook，您可以使用 '''Your multiline String''' 或 """Your multiline ${GString}""".

制作多行字符串

我不太确定 bash 语法，但根据 these docs.

，您似乎还缺少 if [ -e dev.ear ] 后的分号

综合起来：

output = sh returnStdout: true, script: """/bin/rm -rf ${ziptmp}; /bin/mkdir ${ziptmp}; cd ${ziptmp}; /usr/bin/unzip -qq ${tempdir}/${artifactFilename}; ls -ltr; echo *; 
    if [ -e dev.ear ];
    then
        scp dev.ear lsfi@${serverName57}:/apps/wls/dev/applications;
        echo "COPIED DEV ARTIFACT TO SERVER"
    else
        echo "DEPLOYMENT PACKAGE DOESNT CONTAIN DEV ARTIFACT"
    fi"
echo "RESULT::: ${output}"""
