Processing DSL script Pipeline.groovy in Jenkins

Question

I am getting below errors while executing Jenkins job that is made for pipeline creation using groovy script. I am getting no clue how to fix it.

**Processing DSL script Pipeline.groovy
ERROR: (Pipeline.groovy, line 82) No signature of method: Pipeline.buildFlowJob() is applicable for argument types: (java.lang.String, Pipeline$_run_closure1$_closure6) values: [/Jen/Build/SysInfo/Pipelines/check/jobs/Build-Flow, Pipeline$_run_closure1$_closure6@346365c9]**

The error is pointing to below line of code in groovy script:

**buildFlowJob(under_folder+"Build-Flow") {
    displayName("Build " +jobtest)
    parameters {
        stringParam('Test_PREFIX','','Environment  pre-fix')
        stringParam('branch',feature_branch,'Feature Branch to build')
         labelParam('HOMESlave')    
    }**
