Jenkins Jira steps - Groovy code in Declarative Pipeline

Question

Seems like Jira steps works only in Scripted pipeline . How can I make use of JIRA steps inside Declarative pipeline ? I get the error Unsupported map entry expression for CPS transformation when I try defining Jira steps inside pipeline.

stages {    
    stage('Create JIRA Ticket'){            
        steps{          
            
            script {
                def jiraserver = "Demo"
                
                def testIssue = [fields [
                        project [id: '10101'],
                        summary: '[Test] Code Scan - $BUILD_NUMBER ',
                        description: 'Automated Pipeline',
                       customfield_1000: 'customValue',
                       issuetype: [id: '10000']]]
                    
                response = jiraNewIssue issue: testIssue
                echo response.successful.toString()
                echo response.data.toString()
                
                jiraAddComment site: 'Demo', idOrKey: 'Test-1', comment: 'Started Unit Tests'
            }
        }               
    }

I get the error WorkflowScript: 42: Unsupported map entry expression for CPS transformation in this context @ line 42, column 17 project [id: '10101'],

You have several syntax issues on the testIssue parameter definition which causes the Unsupported map entry expression exception.
The issues is that fields and project are dictionary keys and should be followed with : .
In addition if you wish to interpolate the BUILD_NUMBER in the summary use double quotes ( "" ).

The following should work:

    def testIssue = [fields: [
                        project: [id: '10101'],
                        summary: "[Test] Code Scan - $BUILD_NUMBER",
                        description: 'Automated Pipeline',
                        customfield_1000: 'customValue',
                        issuetype: [id: '10000']]]
