Active Choice Plugin 2.5.6 Reactive Reference Parameter Formatted HTML cannot access environment variables

XMLWordPrintable

      I want to access environment variables in a Reactive Reference Parameter Formatted HTML parameter.

      I have a MultibranchPipeline Job in which I want to populate a parameter with dynamic values based on the branch name.

      My use case: I have an Azure Container Registry in which I have Docker Images with the following pattern: <branch_name>/<project>. In my multibranch pipeline job, I would like to access only the projects on that branch. 

      I tried to use the env.BRANCH_NAME variable but I couldn't manage to. I guess that value is populated at build time, and I can't access it beforehand.

      My code:

      [
    $class: 'DynamicReferenceParameter',
    choiceType: 'ET_FORMATTED_HTML',
    name: 'Tag',
    omitValueField: true,
    description: 'Select the tag to be deployed.',
    script: [
        $class: 'GroovyScript',
        fallbackScript: [
            classpath: [],
            sandbox: false,
            script: '''
                return """
                    <label for='value'>Error: The script failed or it is not allowed by Jenkins. Check Script approval from General Settings. Enter the value manually:</label><br>
                    <input type='text' name='value'>
                """
            '''
        ], 
        script: [
            classpath: [],
            sandbox: false,
            script: '''
                def jsonSlurper = new groovy.json.JsonSlurper()
                def acrCred = jenkins.model.Jenkins.instance.getExtensionList('com.cloudbees.plugins.credentials.SystemCredentialsProvider')[0].credentials.find { it ->
                    it.getId() == 'my_id'
                }
                
                def acrUsername = acrCred.getUsername()
                def acrPassword = acrCred.getPassword().getPlainText()
                
                def auth = "${acrUsername}:${acrPassword}".bytes.encodeBase64().toString()
                def tags = ['projA', 'projB'].collect { name ->
                    def req = (HttpURLConnection) new URL("https://${acrUsername}.azurecr.io/acr/v1/${env.BRANCH_NAME}/${name}/_tags").openConnection()
                    req.setRequestProperty('Authorization', "Basic ${auth}")
                    def result = jsonSlurper.parseText(req.inputStream.text)
                    result.tags.sort { a, b -> b.createdTime <=> a.createdTime }.collect { it.name }
                }
                
                tags = tags[0].intersect(tags[1])
                def html = "<select name='value'>"
                tags.forEach { tagName ->
                    html += "<option value='${tagName}'>${tagName}</option>"
                }

                html += "</select>"
                return html
            '''
        ]
    ]
]

      I'm opening this issue because in your docs you mentioned that we have access to two env variables:

      • jenkinsProject
      • jenkinsBuild

      I tried to use them but I get the following error:

      hudson.remoting.ProxyException: groovy.lang.MissingPropertyException: No such property: jenkinsBuild for class: WorkflowScript

      That error occurs when I use triple double quotes, i.e.:

      script: """jenkinsBuild.foo"""

      If instead, I use triple single quotes my fallback script runs.

       

      My question: Is there any way of getting the branch name in a Reactive Reference Parameter Formatted HTML?
