Source `git-tree-sha1` written to `build/environments`

[stemann]

The git-tree-sha1 written to build/environments seem to be that of the source package - and not the rewritten packages. Not sure if this is intended?

More elaborate description:

When doing julia --project bundle.jl for a package named Foo from a private registry, where Foo exists in General (but with a different UUID), the git-tree-sha1 written to build/environments/ExampleEnv/Manifest.toml is that of the source package (b7a1e1a09fc1a40240dcce5a5c39f1e4b7920661) and not the git-tree-sha1 of the re-written package (in build/packages), which makes Pkg.instantiate() fail:

julia --project=environments/ExampleEnv --eval 'using Pkg; Pkg.instantiate()'

ERROR: Foo: git object b7a1e1a09fc1a40240dcce5a5c39f1e4b7920661 could not be found

Not using the environment in build/environments/ExampleEnv works just fine:

julia --eval 'using Pkg; Pkg.add("Foo"); using Foo; print(read(pathof(Foo), String))'
module Foo
cd(@__DIR__) do
    pkgid = Base.PkgId(Base.UUID("9e88b42a-f829-5b0c-bbe9-9e923198166b"), "Serialization")
    buffer = seekstart(IOBuffer(xor.(read("Foo.jl.$(VERSION).jls"), 0x0a)))
    for x in Base.invokelatest(Base.require(pkgid).deserialize, buffer).args
        Core.eval(@__MODULE__, x)
    end
end
end
