"paket.exe pack" with "include-referenced-projects" and "minimum-from-lock-file" does not work when project references have a paket.template file

[Rcomian]

Description

Packing nuget packages does not work when you have this situation:

• Project references to other nuget packages
• the switch include-referenced-projects
• the switch minimum-from-lock-file

Repro steps

• Create a solution with 2 c# projects PackageA & PackageB
• Give both projects a minimally working paket.template file with the line type project
• Add a reference from PackageB to PackageA
• run the command .paket\paket.exe pack output . include-referenced-projects minimum-from-lock-file

Expected behavior

• 2 Packages, PackageA.nupkg & PackageB.nupkg
• PackageB.nupkg includes a reference to PackageA.nupkg but not its assembly

Actual behavior

Command fails with:

Paket failed with:
        The input sequence was empty.
Parameter name: source

With the -v switch we get the stack trace:

Known workarounds

• Remove switch include-referenced-projects
• Remove switch minimum-from-lock-file
• Remove the reference between the two projects
• Remove the paket.template from PackageA

However, all of these options affect the output nupkg.
The least damaging is probably removing the minimum-from-lock-file flag.
