Intermittent Paket.Restore.props error in 5.181.1 - Index was outside the bounds of the array

See original GitHub issue

Description

After upgrading Paket to 5.181.1 from 5.173.1 I get an intermittent build error in Paket.Restore.props.

Repro steps

Run .paket\paket.exe restore
Run dotnet.exe restore MyProject.csproj --no-dependencies

Expected behavior

Packages are restored

Actual behavior

 Checking Paket version (version 5.181.1 requested)...
  Paket.exe 5.181.1 is up to date.
  Paket version 5.181.1
  The last restore is still up to date. Nothing left to do.
  Performance:
   - Runtime: 104 milliseconds
C:\path\to\project\.paket\Paket.Restore.targets(147,5): error MSB4184: The expression ""System.String[]".GetValue(5)" cannot be evaluated. Index was outside the bounds of the array.

Known workarounds

Delete all un-source-controlled files and rebuild.

That is actually a good point. I fucked up here. Let me try to fix it myself.

Possibly, but at the same time, I’ve never seen a similar tool that requires major intervention on a minor version upgrade. It should be able to either deal with it, or self-heal.

It seems to be reliably trigger-able by a dirty workspace.

In my case, Project\obj\Project.csproj.netstandard2.0.paket.resolved, Project\obj\Project.csproj.net46.paket.resolved and similar are CSV files with only 5 columns, not 6.

e.g.

Newtonsoft.Json,11.0.2,Transitive,Main,false
Microsoft.AspNet.WebApi.Client,5.2.6,Direct,Main,false

I assume that either:

Paket did not know to invalidate this and recompute this intermediary file, or
Paket does know to invalidate and recompute, but does that at some point after the MSBuild parsing runs and crashes.
