如何在 Jenkins Groovy 的多行 shell 脚本中同时使用 Groovy 定义的和 OS 系统变量

Question

我需要在 Jenkins 的多行 shell 脚本中访问 Groovy 定义的变量（例如 var1）。我需要在sh中使用双引号"""。（我指的是here）

但我也需要读取和更改 os 系统变量（例如 aws_api_key）。它需要在 sh 中使用单引号 ''' 并使用 \ 来转义美元 $ 符号。（我指的是这里）

我怎样才能同时使用它们？任何帮助都感激不尽。

例如

node ("Jenkins-Test-Slave") {
stage ("hello world") {
    echo 'Hello World'
}

def var1="bin"
stage ("test") {
    withEnv(["aws_api_key='define in withEnv'","service_url=''"]) {
        echo var1
        sh '''
            echo the groovy data var1 is "${var1}",'\${var1}',\$var1,${var1},var1!!!
            echo default value of aws_api_key is \$aws_api_key
            aws_api_key='changed in shell'
            echo new value of aws_api_key is \$aws_api_key

            export newvar='newxxx'
            echo the new var value is \$newvar
        '''
    }
}
}

结果是：

+ echo the groovy data var1 is ,${var1},,,var1!!!
the groovy data var1 is ,${var1},,,var1!!!
+ echo default value of aws_api_key is 'define in withEnv'
default value of aws_api_key is 'define in withEnv'
+ aws_api_key=changed in shell
+ echo new value of aws_api_key is changed in shell
new value of aws_api_key is changed in shell
+ export newvar=newxxx
+ echo the new var value is newxxx
the new var value is newxxx

Answer 1

代替 multi-line String( ''') 使用 multi-line GString( """) 使字符串插值工作，然后${var1}将按预期进行插值：

sh """
    echo the groovy data var1 is "${var1}",'\${var1}',\$var1,${var1},var1!!!
    echo default value of aws_api_key is \$aws_api_key
    aws_api_key='changed in shell'
    echo new value of aws_api_key is \$aws_api_key

    export newvar='newxxx'
    echo the new var value is \$newvar
"""

def var1 = 'bin'

//the following are `groovy` strings (evaluated)

sh "echo var1 = $var1"
//outputs> echo var1 = bin

sh "echo var1 = ${var1}"
//outputs> echo var1 = bin

sh """echo var1 = ${var1}"""
//outputs> echo var1 = bin

sh "echo var1 = \$var1"
//outputs> echo var1 = $var1

//the following are usual strings (not evaluated)

sh 'echo var1 = $var1'
//outputs> echo var1 = $var1

sh '''echo var1 = $var1'''
//outputs> echo var1 = $var1

所以，在你的情况下只需使用

def var1 = 'bin'
sh """
   echo var1 = $var1
   shell_var = 'yyy'
   echo shell_var = \$shell_var
""""
