How to automate the changing of P4 client specs on a Jenkins build process for multiple build jobs?

Question

Context:

• One machine that uses Jenkins as a DOS-Jenkins service (not a Windows service).
• Source-Code Management is handled using a Perforce plugin.
• There is another job on the same machine that uses the Perforce plugin to sync files but from a different Perforce server.

Problem:

• The first task in the build process is a Windows-batch command that performs a force sync of a particular file.

p4 sync -f //depot/directory1/BuildVersion.cs

• However, the console output displays the following message:

C:\Users\<username>\.jenkins\workspace\<workspace_name>>p4 sync -f //depot/directory1/BuildVersion.cs 
//depot/directory1/BuildVersion.cs - must refer to client '<clientname>'.

C:\Users\<username>\.jenkins\workspace\<workspace_name>>exit 1 
Build step 'Execute Windows batch command' marked build as failure
Finished: FAILURE

Steps to try and address this issue:

• I have tried following the advice in the documentation, which can be found here, or alternatively, see the image below -- to no avail, possibly because I'm not understanding it.

• I have tried adjusting both build processes manually so that the p4 config client specification matches their respective build configurations -- however, the console outputs the same error message.

There is obviously a conflict with the P4 configurations conflicting with one another, and I would appreciate a solution that allows for both build processes to work with different P4 configurations using a DOS-Jenkins infrastructure.
