I follow this approach and still get the same merge conflicts coming repeatedly while doing rebase.

Let's say in my feature branch in the first commit I change a line in a file which also gets changed in the main branch. Then I have done 3-4 change commits doing changes in the same file. Now while doing rebase, I will have to resolve this conflict 3–4 times again and again while git re-applies commit one by one, during rebase.

I think I get this sometimes even if rerere is enabled, I am doing rebase using Intellij though, so maybe rerere doesn't get used here somehow or maybe diff context changes, so rerere is not applicable.
