In a file, I have this 2 lines one below the other:

Repository: myvalue
Tag: 8.2.10

On my local branch i have updated repository myvalue.
On the upstream repo, they updated often the tag value (not updated
of my side).

When i perform a merge from upstream to local branch, i have a conflit.
It seems that it’s related to neighboring lines.
Could you confirm that it ‘s a normal git operation?

Also, i need to automate this merge. Is It possible with git tools to
avoid this conflict or to resolve this conflict automatically?

I try to keep version-specific identifying information, which is already

contained in git, out of my code. This includes change logs/history in each
source file because git is good at keeping that information - it is redundant in
the code. However, for organizations that need to do that, I suggest using
clean/smudge filters so that the code inside the repository is clean, while
things like the repo name and tag get injected into the code as git puts it into
the working directory. The code is then cleaned up while being staged. This
removes the possibility of the conflict on these lines by removing the
differing lines. You can script this using a combination of sed and git
commands. My own git front end does this all the time but it is not generally
applicable to all platforms (only NonStop and MVS) so I have not contributed
it.

Regarding the clean/smudge filters usage, do you know if this filters could be
triggered by the merge git? Indeed, it would good if the change performed
by the filters could be integrated with the merge commit.

I do not think my point came across. The idea is that the merge should not even see the lines that are causing the conflict because they are not in the file. Your file should have something like the following inside:

Repo: $repo$
Tag: $tag$

A smudge filter can replace the $repo$ with your repository name, and $tag$ with whatever appropriate tag is. A clean filter would remove the conflicting content so merge would never see it.

If you are going to change the same line in each version just to identify that the version changed, you are always going to get conflicts.

[DO NOT DO THE FOLLOWNG] It is like doing the following:

Commit abc1213:

   Line1: This is version 1.0.

Commit 3533adf:

   Line1: This is version 1.1.

This is not how git is intended to be used, in my view.
