Paket pack seems to evaluate all templates it finds even when using the --template switch

[wastaz]

Description

When running paket pack with the --template switch it seems that paket still goes looking at other paket.template files than the one provided. This is all fine as long as all other paket.template files it can find are ok, but if for some reason they arent (in this case because of only partially compiling the solution) paket still fails even though the packing of the template file given by the --template switch would work fine.

Repro steps

Check out the following reproduction repo: https://github.com/wastaz/paket-template-repro
Run ./build.sh targetHost=ProjectA

Expected behavior

This project contains two projects, ProjectA and ProjectB, each of these has its own paket.template file (and is meant to be pushed as two separate nugets). They have no references to each other.
By running ./build.sh targetHost=ProjectA it should build only ProjectA and then pack only ProjectA. So I expect this to correctly produce a ProjectA nuget package.

Actual behavior

However paket fails with the following message.
I've also tried running this without FAKE, and I get the exact same output and problem.

Notice how what it is complaining about is that it could not find ProjectB.dll, which is of course correct since we have not compiled ProjectB and we do not need ProjectB in order to pack ProjectA.

Known workarounds

Always compile everything or remove all other paket.template files...

it is due to my fix for #1848.
Sorry, i thought pack partially compiled solution is not required.
I see two solutions:

• ban usage --include-referenced-projects with --template ... and evaluate only one template with --template
• evaluate all templates with --template only if --include-referenced-projects

@wastaz do you use --include-referenced-projects flag with pack command (or in template file)?

[wastaz]

@lexarchik No, I do not.
