Question

我需要在Jenkins的多行shell脚本中访问Groovy定义的变量（例如var1）。我需要使用双引号＆＃34;＆＃34;＆＃34;在sh。（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）。它需要使用单引号＆＃39;＆＃39;＆＃39;在sh并使用\来逃避美元$符号。（我指的是here）

我如何同时使用它们？任何帮助都感激不尽。

e.g。

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

使用多行GString（'''）来使字符串插值工作，而不是多行字符串（"""），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
"""

DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true);
Document doc = dbf.newDocumentBuilder().parse(isIn);
DOMHelper.useIdAsXmlId(doc.getDocumentElement());

KeyStore ks = KeyStore.getInstance("Windows-ROOT", "SunMSCAPI");
ks.load(null, null);
CertificateValidationProvider validationProviderMySigs = new PKIXCertificateValidationProvider(ks, false, null);
XadesVerificationProfile instance = new XadesVerificationProfile(validationProviderMySigs);
XadesVerifier verifier = instance.newVerifier();
XAdESVerificationResult r = verifier.verify(getSigElement(doc), null);

所以，在你的情况下只需使用

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
