Paket: 5.92.0-alpha001 fail to generate correct project.assets.json

[MangelMaxime]

I just updating one of my project to use NETStandard 2.0.

When using paket 5.92.0-alpha001 I got this project.assets.json which is wrong. It does not contains my dependencies.

If I use paket 5.91.0, then I got this file.

As you can see the first file is missing a lot of deps like Fable.Core.

Here is my paket.dependencies:

framework: netstandard2.0

source https://www.nuget.org/api/v2

nuget Fable.Core prerelease
nuget Fable.Elmish.React
nuget Fable.Elmish.Browser
nuget Fable.Elmish.Debugger
nuget Fable.PowerPack
nuget Fable.React prerelease

clitool dotnet-fable prerelease

group Build
framework: net46

    source https://nuget.org/api/v2
    nuget FSharp.Core  redirects:force, content:none
    nuget FAKE

    github fsharp/FAKE modules/Octokit/Octokit.fsx

Paket.references:

Fable.Core
Fable.React

Please tell me if you need more infos.

Yes

• what is your project layout, ie relative paths of project file, paket.references file, paket.exe, Paket.Restore.Targets and lockfile. Please make sure everything is correct regarding to casing if you are not on windows
  • what are the generated *.references files in the obj/ directory.
  • dependencies-/lock- file
  • Are there warnings errors emitted by paket in your build process?

Hello @matthid you can find the project here.

To summarize I go the following layout:

/.paket/paket.exe
/paket.lock
/paket.dependencies
/src/Fulma/paket.reference
/src/Fulma/Fulma.fsproj

Here is my Fulma.fsproj.netstandard2.0.references file.

And here is my full obj folder: obj.zip

There is no warning output during my build process by paket. output.txt

Ah good, will try to reproduce later

[matthid]

Ok can you tell me for idiots what I need to do :)

Assume I don't have any idea of fable and just cloned your repository, how do I reproduce the bug?

[matthid]

Problem is all your files look correct, but from your error description it looks like they are never actually read in the build process. Something is wrong there.

[matthid]

OK I noticed something: Your Paket.Restore.targets is not the latest one and paket install didn't update it either. Now I have two questions:

• @forki what else do I need to do apparently something else is required to embed/update the targets file?
• Apparently I broke compat with older Targets files, thanks for the report, because I expected this to work...

[matthid]

Ah OK its because I removed the old file when only netstandard20 is there (We discussed that it is safe to assume it only is required for fable compat when using netstandard16). Maybe we need to revisit that for at least a couple of versions... (until we can assume people have updated their targets files?)

/cc @forki because of compat concerns

[forki]

I always tried to keep paket backwards compatibility with the old targets files. It's not easy,...

Will be fixed with https://github.com/fsprojects/Paket/pull/2684, thanks for reporting and testing the alpha!

[MangelMaxime]

Thanks for the quick fix :)

I tested with 5.92.0-beta001 and it's working. 👏
