Quickly Migrate NuGet Packages to a New Feed

Summary

This is a very simple bash script that can assist you in migrating NuGet packages to a different Artifact feed. It’s written with Azure DevOps in mind as a target, but there’s no reason why you couldn’t use any other artifact feed as a destination.

I used the script after I ran a NuGet restore locally of a Visual Studio solution, found my .NuGet folder with all of the cached packages, placed my script in that folder, and ran it. This saved me a lot of time, migrating 102 packages while I grabbed a cup of coffee ☕️!

Note that this won’t work for migrating NuGet packages to GitHub Packages since the <repository url="..." /> element in the .nuspec file in the .nupkg needs to be updated. See my other posts:

The Script

Copy the script below and save it as nuget-pusher.sh in the folder where your .nupkg files are located. Don’t forget to chmod +x nuget-pusher.sh to make it executable!

#!/bin/bash

# Usage: ./nuget-pusher-script.sh <nuget-feed-name> <nuget-feed-source> <PAT>

if [ -z "$3" ]; then
    echo "Usage: $0 <nuget-feed-name> <nuget-feed-source> <PAT>"
    exit 1
fi

echo "..."

NUGET_FEED_NAME=$1
NUGET_FEED_SOURCE=$2
PAT=$3

# adding to ~/.config/NuGet/NuGet.config
dotnet nuget add source \
  $NUGET_FEED_SOURCE \
  --name $NUGET_FEED_NAME \
  --username "az" \
  --password $PAT \
  --store-password-in-clear-text

results=$(find . -name "*.nupkg")
resultsArray=($results)

for pkg in "${resultsArray[@]}"
do
    echo $pkg
    dotnet nuget push --source \
      $NUGET_FEED_NAME \
      --api-key az \
      $pkg
done

# clean up
dotnet nuget remove source $NUGET_FEED_NAME

echo "..."

According to the docs, any string will work for the --api-key parameter.

Running the Script

The script below can be called via:

./nuget-pusher-script.sh <nuget-feed-name> <nuget-feed-source> <PAT>

An example:

./nuget-pusher-script.sh \
  azure-devops \
  https://pkgs.dev.azure.com/jjohanning0798/_packaging/my-nuget-feed/nuget/v3/index.json \
  xyz_my_pat

Bonus: Locating .nupkg Packages

How to find the location of .nupkg files:

find / -name "*.nupkg" 2> /dev/null

How to find the location of .nupkg files and copy them all to a directory:

find / -name "*.nupkg" -exec cp "{}" ./my-directory  \; 2> /dev/null

The 2> /dev/null is to suppress permission errors.

Improvement Ideas

• The username doesn’t matter in this script since when using an Azure DevOps PAT, username is irrelevant. If one was pushing to a NuGet feed that required username authentication, I would presume you would add that as an input.
• One could also add a source folder as an input too instead of relying on current directory
• Also one could use a more elaborate input mechanism to the script…
• Use dotnet nuget instead of nuget command
• Support other systems (such as ubuntu) with --store-password-in-clear-text flag
• Clean up temporary NuGet source when done
