Confused by stack's behaviour when changing targets

[Arnaud Bailly]

Hello (and Happy New Year to the list),

I am a little bit puzzled by stack's behaviour w.r.t to build targets selection. 

Within a multi-package project, I can run

$ stack test 

to build and test all packages, pr

# stack test mypackage

to select which package to build.

When I switched from one to the other I noticed that the whole dependency graph is rebuilt: Is this expected? And if so, why is it the case?

Regards,

It's a bug that was just fixed on master and stable. See https://github.com/commercialhaskell/stack/issues/3732
