Fail to upload Python dependencies for Xray scan in pipBuild

Describe the bug
When we use Artifactory plugin to build python script and upload the package to Artifactory. Zero dependencies were uploaded

To Reproduce

1. Create Python type local repo on artifactory server: Python-Test

2. Create Jenkins job to install and upload python packages as below

    stage('setup') { 
        steps {
           	script {
    			echo "artifactory Server name = ${artifactoryServer}"
           		rtServer = Artifactory.server "${artifactoryServer}"
                
           		rtPip = Artifactory.newPipBuild()
           		rtPip.resolver repo: appJson.virtualName, server: rtServer
           		
      			buildInfo = Artifactory.newBuildInfo()
    	        buildInfo.env.capture = true
    	        scanConfig = [
    	            'buildName'      : buildInfo.name,
    	            'buildNumber'    : buildInfo.number,
    	            'failBuild'      : false
    	        ]
   			}
    	}
    }
    
    stage('VirtualEnv') {
        steps {
            dir("${deployLocation}app/${repo}") {
                script {
    				virtual_env_activation = 'source activate "${repo}"'
    				sh'''                        
    				pwd
                    find . -iname "requirements.txt" | more
    				'''
    				requirements = readFile "./requirements.txt"
    				echo "requirements.txt = ${requirements}"
    				rtPip.install buildInfo: buildInfo, args: '-r "./requirements.txt"', envActivation: virtual_env_activation
            	}
            }
        }	
    }
   

   stage ('Package and create distribution archives') {
   steps {
   dir("${deployLocation}app/${repo}") {
   script {
   sh '''
   source activate "${repo}"
   python setup.py sdist bdist_wheel
   '''
   }
   }
   }
   }

   stage ('Upload packages') {
   steps {
   dir("${deployLocation}app/${repo}") {
   script {
   def uploadSpec = """{
   "files": [
   {
   "pattern": "./dist/",
   "target": "Python-Test/package/"
   }
   ]
   }"""
   rtServer.upload buildInfo: buildInfo, spec: uploadSpec
   }
   }
   }
   }

        stage('PublishBuildInfo') {
      	steps {
        	script {
    	    	rtServer.publishBuildInfo buildInfo
   			}
    	}
    }
   

After the package uploaded, zero dependencies were uploaded.

Below is the python requirements.txt file:
PyYAML==5.4.1
pytest==6.1.2
pytest-cov==2.11.1
requests==2.18.4
dse-tools==1.1.0
pandas==0.20.3
psutil==5.7.3
xlrd==1.2.0
openpyxl==3.0.5
pylint==2.6.0
jsonschema==3.2.0
feather-format==0.4.1
pyarrow==0.17.1

Expected behavior
We are building Python script on jenkins slave agent server. We have already installed and setup the python environment. All of the dependencies have already been downloaded into jenkins slave server. This is not a best practice to download dependency from artifactory every time when we build python script. We hope the plugin could upload the reqirements.txt to artifactory server to allow XRay to scan the dependencies.

If applicable, add screenshots to help explain your problem.

Versions

• Jenkins Artifactory plugin version: 3.10.6
• Jenkins operating system: Red Hat Enterprise Linux Server release 7.8 (Maipo)
• Artifactory Version: 6.16.0

Additional context
Add any other context about the problem here.

Start by reproducing the Jenkins pipeline with Artifactory plugin 3.10.6, focusing on rtPip.install, buildInfo, and the upload and publishBuildInfo stages. Verify whether locally installed requirements are recorded in build information for Xray scanning. Done means the listed dependencies are associated with the published build without requiring a fresh download.
