Multiple pipeline with single repository

Hi,

I would like to create multiple pipeline with single repository using classic.  Its a gradle build and the jar name specified in build.gradle file. (

Pipeline created as below. 

testODD and testEven

If i trigger the odd build it could generate the jar like. test.odd-1.0.1.jar.

currently odd flow working fine. now i need to generate the the even jar. I dont want to create one more branch for even. 

How can i acheive this.
