Validate the code coverage of Apex test classes from Jenkins before deployment (Continuous Integration using Salesforce DX and Jenkins)

Question

Can anyone help me to set up configurations to validate the code coverage of Apex test classes before deployment through Jenkins (Continuous Integration)? Here is a snippet from my Jenkins file.

#!groovy
import groovy.json.JsonSlurperClassic
node {
    def BUILD_NUMBER = env.BUILD_NUMBER
    def RUN_ARTIFACT_DIR = "tests/${BUILD_NUMBER}"
    def SFDC_USERNAME
    def TEST_LEVEL='RunLocalTests'
    def HUB_ORG = env.HUB_ORG_DH
    def SFDC_HOST = env.SFDC_HOST_DH
    def JWT_KEY_CRED_ID = env.JWT_CRED_ID_DH
    def CONNECTED_APP_CONSUMER_KEY = env.CONNECTED_APP_CONSUMER_KEY
    println 'KEY IS' 
    println JWT_KEY_CRED_ID
    println HUB_ORG
    println SFDC_HOST
    println CONNECTED_APP_CONSUMER_KEY
    def toolbelt = tool 'toolbelt'
    stage('checkout source') {
        //When running in multi-branch job, one must issue this command
        checkout scm
    }
    withCredentials([file(credentialsId: JWT_KEY_CRED_ID, variable: 'jwt_key_file')]) {
        stage('Authorize to Dev Org') {
            if (isUnix()) {
                rc = sh returnStatus: true, script: "${toolbelt}/sfdx force:auth:jwt:grant --client-id ${CONNECTED_APP_CONSUMER_KEY} --username ${HUB_ORG} --jwt-key-file ${jwt_key_file} --set-default-dev-hub --instance-url ${SFDC_HOST}"
            } else {
                rc = bat returnStatus: true, script: "\"${toolbelt}/sfdx\" force:auth:jwt:grant --client-id ${CONNECTED_APP_CONSUMER_KEY} --username ${HUB_ORG} --jwt-key-file \"${jwt_key_file}\" --set-default-dev-hub --instance-url ${SFDC_HOST}"
            }
            if (rc != 0) { error 'hub org authorization failed' }
        }
       stage('Check Apex Test Coverage') {
            if (isUnix()) {
                rmsg = sh returnStdout: true, script: "${toolbelt}/sfdx force:source:deploy:report -u ${HUB_ORG} --test-level ${TEST_LEVEL} --code-coverage"
            } else {
                rmsg = bat returnStdout: true, script: "\"${toolbelt}/sfdx\" force:source:deploy:report -u ${HUB_ORG} --test-level ${TEST_LEVEL} --code-coverage"
            }
            def jsonSlurper = new JsonSlurperClassic()
            def report = jsonSlurper.parseText(rmsg)

            if (report.status == 'Succeeded') {
                if (report.result.totalCoverage < 75) {
                    error "Code coverage (${report.result.totalCoverage}%) does not meet the minimum requirement (75%)."
                }
            } else {
                error 'Failed to retrieve code coverage report.'
            }
        }
        stage('Deploy Code') {
            // need to pull out assigned username

            if (isUnix()) {
                rmsg = sh returnStdout: true, script: "${toolbelt}/sfdx force:source:deploy --manifest manifest/package.xml -u ${HUB_ORG}"
            } else {
                rmsg = bat returnStdout: true, script: "\"${toolbelt}/sfdx\" force:source:deploy --manifest manifest/package.xml -u ${HUB_ORG}"
            }             
       printf rmsg
            println('Hello from a Job DSL script!')
            println(rmsg)
        }
    }
}

I tried with the above snippet the org were authorized succuessfully but getting this error on the stage of running a test classes "Error (2): Nonexistent flags: --test-level, --code-coverage See more help with --help C:\ProgramData\Jenkins.jenkins\workspace\AssignmentOrgDeployment>"C:\Program Files\sf\bin/sfdx" force:source:deploy:report -u [email protected] --test-level RunLocalTests --code-coverage "
