get all file from specific folder from a commit in pipeline scripts

[vmunisamy]

I'am actually trying to get all files and folder from a git commit  from my branch, to place them in a certain directory that need to be created, so that in my script when ant is run it take those files into considerations for deployment. 

I know how to create a new repo in ant, but before that I need to get only those files in the last commit on the branch.

Here are the tools available in my docker image to write the script : 

My pipeline look like this : 

image:  
  name: abhisheksaxena7/salesforcedockerimg
pipelines:  
   branches:      
     lot2:      
       - step:          
         deployment: Test          
         script:           
          - ant -buildfile build/build.xml getCode -Dsfdc.username=$SFDC_SRC_USERNAME -Dsfdc.password=$SFDC_SRC_PASS$SFDC_SRC_TOKEN -Dsfdc.serverurl=https://$SFDC_SERVERURL -Dsfdc.retrieveTarget=src            
          - ant -buildfile build/build.xml deployEmptyCheckOnly -Dsfdc.username=$SFDC_USERNAME -Dsfdc.password=$SFDC_PASS$SFDC_TOKEN -Dsfdc.serverurl=https://$SFDC_SERVERURL -Dsfdc.retrieveTarget=src

 Instead of the first line in the script for retrieving the code from my salesforce org, I want to get the files from my last commit and write them to the folder i will specify as the sfdc.retrieveTarget variable. I have no idea what to write to achieve this
