在jenkinsfile groovy中执行bash命令

Question

请帮忙

在这里，我有一部分 Jenkinsfile 像

@Library('groovy_shared_libraries')_

stage("Ensure droplet don`t exist and Create DO Droplet") {
    // Ensure droplet don`t exist
    ExistDroplet = sh(
        script: "doctl compute droplet list | awk '{gsub(/\./, "", $2)} 1' | grep -w $(echo $FullDomainName | sed "s/\.//g") | awk '{ print $2 }' | wc -l"
        returnStdout: true
    ).trim()

我如何在 jenkinsfile groovy 中执行这个 bash 命令？

doctl compute droplet list | awk '{gsub(/\./, "", $2)} 1' | grep -w $(echo $FullDomainName | sed "s/\.//g") | awk '{ print $2 }' | wc -l

使用当前的实现，它返回一个错误

WorkflowScript: 26: unexpected char: '\' @ line 26, column 63.
   te droplet list | awk '{gsub(/\./, "", $

如果我在命令中添加额外的 \ 我有这个错误

WorkflowScript: 26: illegal string body character after dollar sign;
   solution: either escape a literal dollar sign "\$5" or bracket the value expression "${5}" @ line 26, column 21.
           script: `"doctl compute droplet list | awk '{gsub(/\\./, "", $2)} 1' | grep -w $(echo $FullDomainName | sed "s/\\.//g") | awk '{ print $2 }' | wc -l",`

添加转义后 $2 jenkins 显示此错误

WorkflowScript: 26: illegal string body character after dollar sign;
   solution: either escape a literal dollar sign "\$5" or bracket the value expression "${5}" @ line 26, column 21.
           script: `"doctl compute droplet list | awk '{gsub(/\\./, "", \$2)} 1' | grep -w $(echo $FullDomainName | sed "s/\\.//g") | awk '{ print \$2 }' | wc -l",`

这一切都适用于这个命令doctl compute droplet list | grep -w \"$FullDomainName\" | awk '{ print \$2 }' | wc -l doctl compute droplet list | grep -w \"$FullDomainName\" | awk '{ print \$2 }' | wc -l doctl compute droplet list | grep -w \"$FullDomainName\" | awk '{ print \$2 }' | wc -l但我需要添加

 awk '{gsub(/\\./, "", $2)} 1' | grep -w $(echo $FullDomainName | sed "s/\\.//g")

\是 shell 和 Jenkins 的转义字符。 如果您想将反斜杠字符发送到 shell 您需要使用另一个用于 Jenkins 的反斜杠字符（注意\\ ）：

script: "doctl compute droplet list | awk '{gsub(/\\./, "", $2)} 1' | grep -w $(echo $FullDomainName | sed "s/\\.//g") | awk '{ print $2 }' | wc -l"
