No such property: api for class: groovy.lang.Binding error

Question

Im trying to build a pipeline on Jenkins that runs a command on node and informs me of the following error:

 groovy.lang.MissingPropertyException: No such property: api for class: groovy.lang.Binding
        at groovy.lang.Binding.getVariable(Binding.java:63)

        at com.cloudbees.groovy.cps.impl.PropertyAccessBlock.rawGet(PropertyAccessBlock.java:20)

i dont know the node command its an error command or its for another error this is de pipeline file:

def call() {
        pipeline { 
            agent any 
            
            parameters {
                string(name: 'branch', defaultValue: 'refs/heads/develop', description: 'git branch where fetch sourcecode')
            }
            
            environment {
                GIT_URL = getGitRepoURL()
                GIT_CREDENTIALS = '*******'
            }
            
            tools {
                nodejs "node"
            }
            
            triggers {
                cron('H 06 * * 1-5')
            }
            
            stages {
                stage ('Initialize'){
                    steps {

The error you see means that jenkins is finding the word api in your script and tries to interpret is a variable or command of jenkins, and doesn't find a match. I searched for the word api in your script and saw 2 issues:

• You're trying to use a multiline string but you're wrapping it with single quotes. You need to use triple quotes instead (more info on multiline strings here). I think this is causing the error message you see, because pipeline doesn't recognise that the second line of your string is part of a string and not pipeline code.
• You're using batch like variables (%VAR%) in a bash step. You should be using $VAR instead.

Try changing:

   sh 'cd ..\HelpDevelopsAPI
       node raml2html -s %WORKSPACE% -c %WORKSPACE%\..\apidef-aqj-commons -o /server/api --cat .*.html --schema /server/schema/%JOB_BASE_NAME% --mock /server/mock/%JOB_BASE_NAME%
       cd %WORKSPACE%'

to:

   sh '''cd ..\HelpDevelopsAPI
       node raml2html -s $WORKSPACE -c $WORKSPACE\..\apidef-aqj-commons -o /server/api --cat .*.html --schema /server/schema/$JOB_BASE_NAME --mock /server/mock/$JOB_BASE_NAME
       cd $WORKSPACE'''

You're mixing Windows-specific constructs/syntax in the shell task step. In addition to the suggestions made by @vasiliki-siakka: replace the backslash directory separators \ in your strings with forward slash /, and surround the variables with " (double quotes) to handle potential spaces in directory names:

sh '''
    cd ../HelpDevelopsAPI
    node raml2html -s "${WORKSPACE}" -c "${WORKSPACE}/../apidef-aqj-commons" -o /server/api --cat .*.html --schema "/server/schema/${JOB_BASE_NAME}" --mock "/server/mock/${JOB_BASE_NAME}"
    cd "${WORKSPACE}"
'''

OR
if your Jenkins runs on Windows, use the bat task step, and reference the variables in Windows style %VARIABLE_NAME%, but you still have to escape the backslashes like this \\ because the Jenkinsfile syntax is Groovy based. Untested example:

bat '''
    cd "%WORKSPACE%"
    node raml2html -s "%WORKSPACE%" -c "%WORKSPACE%\\..\\apidef-aqj-commons" -o \\server\\api --cat .*.html --schema "\\server\\schema\\%JOB_BASE_NAME%" --mock "\\server\\mock\\%JOB_BASE_NAME%"
    cd "${WORKSPACE}"
'''

I had a similar issue -

No such property: config for class: groovy.lang.Binding error

In my JenkinsFile, I was referencing an object named config - i checked previous version and realised I'd deleted a config object

No such property: config for class: groovy.lang.Binding error

Search your jenkins file and see if you're using an undeclared object.
