Multiple jobs in Jenkins are triggering after code delivery in RTC work stream

Question

I have a work stream in which, I have multiple projects (Components) and for each project i have created a separate jobs in Jenkins.

I am looking the solution for my issue, First i will explain the scenario of my work stream.

Explanation of Jenkins

I have created two separate jobs in Jenkins like (Job for project "A" and Job for project "B"). I am using Ant 1.9.14 for build.

explanation of Issue

All the setup of Jenkins jobs and RTC are done, Jobs are triggering and creating build files successfully.

Main issue is that, Currently i am working on project "A" and doing check-in and delivering code properly in my main work stream for project "A", but as soon as I deliver code in my work stream for project "A" Jenkins build starts for both projects.

So, Is there any way to start a specific project build in Jenkins?
