The Elevator Pitch

the name change cause _rels/.rels file change, and that also cause .nupkg file change, and for someone who using local folder as nuget source ,
then itcause git keep track the same .nupkg every time you pack it (especially，when <GeneratePackageOnBuild>True<GeneratePackageOnBuild>).

Hey @John0King,

I'm not sure I understand your concern.

Can you let us know what you are trying to achieve and the commands you were running and the effect of the problems you encountered.

[John0King]

@nkolev92 I want a local folder to be a nuget source (the folder and the .nupkg file need to store in git repo),
but every time I build my project , the *.nupkg is changed , I find all the binaries are unchanged , so I'm looking into to .nupkg.zip , turn's out the onlything change is that the name of the *.psmdcp file and the metadata contains it's name (eg. .rels)

so every time you build the project with option <GeneratePackageOnBuild>True<GeneratePackageOnBuild>) , the *.nupkg file is change (though all the output is not change)

[nkolev92]

Ah, ok, you are looking for deterministic pack.

so every time you build the project with option True) , the *.nupkg file is change (though all the output is not change)

The pack target has up to date checks that work on the same machine.
Cross machine that's not possible at this point.

On the pack topic, it's not just the _rels folder, but also the timestamps of the dlls that affect the zip.

We attempted this at some point and we hit issues.

Duplicate of #8601.

@nkolev92 : Is it possible to just fix the .pcsdmp file to get a consistent name?

The timestamps are what caused the problem and it's easier to sell diff all the files in the zip file than all but two of them.

@joshudson
I think we can reconsider it.
Upvoting #8601 is probably best since it'd get more attention than this single issue.
Please do share your ideas there.

Not sure when we'd able to get to it, but we'd certainly consider community contributions.
