如何在eclipse中将java的dymanic web项目部署到jenkins，而代码更改更少

I am new to jenkins so i don't know in depth about it. But in recent days we wanted to change from svn repository to GIT in which we have a java project created in dynamic web project. Now we have to deploy this project in jenkins. But i read that in jenkins only projects created in maven are accepted but not any other. Our project is a huge project and its created using dynamic web project. So if we want to convert to maven project will there be any code changes like many?? What are the jar files or any configuration files needed for the change??I am new to jenkins so i don't know in depth ab
