Extension-specific "cannot merge projects"

[timholy]

This seems like a revival of #1585 for package extensions. I've submitted JuliaDiff/ForwardDiff.jl#667 and want to prepare a PR for IntervalArithmetic adding the extension. Note that the master branch of ForwardDiff is currently 0.11-DEV but there is no release yet of the 0.11 branch.

Here's what I have:

tim@diva:~/.julia/dev/IntervalArithmetic$ cat Project.toml
name = "IntervalArithmetic"
uuid = "d1acc4aa-44c8-5952-acd4-ba5d80a2a253"
repo = "https://github.com/JuliaIntervals/IntervalArithmetic.jl.git"
version = "0.21.1"

[deps]
CRlibm = "96374032-68de-5a5b-8d9e-752f78720389"
EnumX = "4e289a0a-7415-4d19-859d-a7e5c4648b56"
FastRounding = "fa42c844-2597-5d31-933b-ebd51ab2693f"
Markdown = "d6f4376e-aef5-505a-96c1-9c027394607a"
Random = "9a3f8284-a2c9-5f02-9a11-845980a1fd5c"
RoundingEmulator = "5eaf0fd0-dfba-4ccb-bf02-d820a40db705"
SetRounding = "3cc68bcd-71a2-5612-b932-767ffbe40ab0"

[weakdeps]
ForwardDiff = "f6369f11-7733-5829-9624-2563aa707210"

[extensions]
IntervalArithmeticForwardDiffExt = "ForwardDiff"

[compat]
CRlibm = "0.7, 0.8, 1"
EnumX = "1"
FastRounding = "0.2, 0.3"
RoundingEmulator = "0.2"
SetRounding = "0.2"
julia = "1.9"

I've also tried adding ForwardDiff = "0.11" to the [compat] but that didn't seem to help.

Then also:

tim@diva:~/.julia/dev/IntervalArithmetic$ rm Manifest.toml
rm: cannot remove 'Manifest.toml': No such file or directory
tim@diva:~/.julia/dev/IntervalArithmetic$ julia +1.10 --project=test -q
(test) pkg> st
Status `~/.julia/dev/IntervalArithmetic/test/Project.toml`

  [90137ffa] StaticArrays v1.6.4
  [37e2e46d] LinearAlgebra
  [9a3f8284] Random
  [8dfed614] Test

This makes sure we start with a clean Manifest for the package and shows the test/Manifest has been set to the dev version of ForwardDiff.

Then:

ERROR: can not merge projects

[timholy]

Note this only seems to happen if the package uses a test/Project.toml. I've verified that if I copy the dependencies into an [extras] section of the main Project.toml then it works.

[IanButterworth]

Is this on master? I thought things improved with #3276

[timholy]

Oh sorry, this is 1.10. I can try master.

[timholy]

Seems fixed on master. Thanks!
