我有一個用例，我必須在 Jenkins Pipeline 中撰寫一個 shell 腳本作為變數并運行它。我的用例的簡短概念如下
pipeline{
agent any
stages{
stage('print Vars'){
steps{
script{
String script = """
export pipelineScriptVar='This is a var'
echo "${pipelineScriptVar}" """
sh script
}
}
}
}
}
當我嘗試運行相同時，我收到以下錯誤。

Finished: FAILURE
但是當我洗掉 echo 步驟并嘗試像這樣 grep 環境變數時。
export pipelineScriptVar='This is a var'
env | grep "pipeline"
我得到了預期的輸出。
uj5u.com熱心網友回復：
在您的情況下，您在一個名為 script 的字串中宣告 pipelineScriptVar，因此當您將此腳本變數作為 shell jenkins 運行時，請考慮將 pipelineScriptVar 作為 jenkins 變數而不是 shell 變數。
So you can use '\' to suppress the string notation of jenkins. Use '\' before ${pipelineScriptVar} like \${pipelineScriptVar}. Hope you find this useful
uj5u.com熱心網友回復：
當您在腳本（或任何其他字串變數）周圍使用雙引號（“）時，字串被插值，變數被 Jenkins 替換。因此，不要用雙引號括起來，而是用單引號括住您的腳本。
pipeline{
agent any
stages{
stage('print Vars'){
steps{
script{
String script = '''
export pipelineScriptVar='This is a var'
echo "${pipelineScriptVar}" '''
sh script
}
}
}
}
}
$或者正如 Dharani 提到的，你可以用反斜杠來逃避。\$
