As a process of rebranding, we have a change the names in one of our huge project.
Is there a way that let me refactor my Java code base (rename class and package) programmatically using eclipse/other tools?

To clarify, you are looking for an alternative to simply using Eclipse's **Refactor > Rename...** functionality? – skomisa Jun 15 '18 at 07:01

yes. Our project is a huge one with lots of packages and classes. Refactoring each and every class/package is not a scalable way. – Kannan Ramamoorthy Jun 15 '18 at 07:03

OK. So you have many names changes to be made to a huge project, and for logistic reasons you'd like them to be performed in a single pass if possible, rather than applying the changes one at a time? – skomisa Jun 15 '18 at 07:20

@skomisa yes. Imagining there could some programmatic way of doing it. – Kannan Ramamoorthy Jun 15 '18 at 07:22

Perhaps this fairly old SO post helps if you are interested in writing the code yourself: [How to programmatically rename a method using JDT](https://stackoverflow.com/questions/12968328/how-to-programmatically-rename-a-method-using-jdt) – skomisa Jun 15 '18 at 08:31

Eclipse has a way of persisting refactorings that you apply into an XML file and gives you the possibility to replay this script later, see https://help.eclipse.org/neon/index.jsp?topic=%2Forg.eclipse.jdt.doc.user%2Fconcepts%2Fconcept-refactoring.htm.
It is not that hard to write this script by hand, especially if you're just renaming code (refactoring within a method-body needs much more fine-grained information).
