Not able to build GammaLauncher in recent previews

vvvv gamma bug
1

Hey bonsoir,

Still trying to use Nuke to streamline GammaLauncher development and easily build multiple versions of the app (don’t want to do that manually 😛)

No matter if I build from vvvvc or from the editor, I’m getting the following error :

21:46:55 [ERR] Unhandled exception. System.InvalidOperationException: Unable to build D:\Documents\dev\apps\GammaLauncher\output\win-x64\src\GammaLauncher\GammaLauncher.csproj. Reason:

To reproduce :

  • Make sure you have 7.0-0361 installed
  • Checkout GammaLauncher at 52bbc0f72d075d619c701ab95438925285f46712
  • cd in /nuke
  • nuke compile --version 10.0.0

Same error occurs if you try to build from the editor after that. If you do so, you’ll most likely have the output path set to /output/win-arm (since nuke will try to do that anyway and thus overwrite the .props file), but it does not really matter for this.

Am I doing something wrong?

Thanks!

It is not related to vvvv directly, it’s about .net and nuget update.
I had the same issue yesterday.
There are two solutions, both require to modify your nuget.config in AppData:

  1. Remove all nuget sources and leave there only default one (nuget.org);
  2. or setup the mapping: Package Source Mapping | Microsoft Learn

Hey, thanks for the feedback!

Indeed, I’m not assuming that’s a direct vvvv issue since the error clearly emanates from a nuget setup, but I assumed something was off in the way vvvv handles that, hence the report :-)

I’ll try the workaround you suggested and report in this post, thanks!

Not sure why but your document references VL.UI.Core a package which is no longer available / only used internally. Simply remove that reference and all good.

It’s working indeed, thanks @Elias!

No idea how/why that was referenced.. but why wasn’t it showing up in red in the dependencies menu? Afaict this could have only been caught up by looking at the XML.

It’s a bit tricky, internally the “package” exists - but we don’t publish it as it contains internal stuff. If you build extensions that thing is for example in play indirectly via “VL.HDE”, another package we don’t publish as it depends on things we want/need to keep internal.

I see, OK. Thanks for clarifying!
