Jenkins neo.sh not found error while using SAP Project Piper Library

I am setting up a CI/CD pipeline scenario for SCP NEO environment based on the prebuilt pipeline on Project Piper. I tried to execute a pre-built library called Project Piper for Jenkins and I got the following error.The error seems neo.sh is not found. But I downloaded neo SDK and placed it in the neo-sdk folder. Also neo.sh is available inside /opt/sap/neo-sdk/neo-java-web-sdk-3.39.10/tools folder in linux

Please see error in Jenkins

please see .pipeline/config file where that location is referenced

Docker is not used and I set-up Jenkins in ubuntu inside Vmware virtual machine.If the docker is not available,the library is capable of running locally in Jenkins server. I am keeping neo-sdk tool in a local folder which contain neo.sh which is used to deploy application to SAP Cloud Platform.I am not writing any script my own as everything is prebuilt scripts from Project piper
