cargo build panic 'target' specifier cannot be used without an 'artifact = …'

[llde]

Problem

Hi,

I get this error
thread 'main' panicked at 'called Result::unwrap()on anErr value: 'target' specifier cannot be used without an 'artifact = …' value (web-sys)', src/tools/cargo/src/cargo/util/toml/mod.rs:1553:14
when I try to compile a project that have some git dependancies. When using the same dependancy from crates all works.
I needed some modification in some dependancies for a program I was working on, so used them with git.

The current behaviour started with
rust 1.61 nightly nightly-2022-04-01-x86_64-unknown-linux-gnu
the version between nightly-2022-02-24-x86_64-unknown-linux-gnu and nightly-2022-03-31-x86_64-unknown-linux-gnu had another error:

error: no matching package named `roctogen` found
location searched: https://github.com/llde/roctogen

roctogen seem the only package affected, not the other packages linked with a git dependancy.

Last nightly version that worked was 2022-02-23

Steps

1.) Create a new project.
2.) use this Cargo.toml manifest: https://gist.github.com/llde/a8d7f437a725534a4a802da6148c715e
3.)cargo build
See the panic happen.
This is a minimal reproducer, with roctogen.

Possible Solution(s)

No response

This is no longer panicking on the latest nightly

[ehuss]

I'm going to close as fixed. The reproducer is no longer available, and I'm not sure how exactly to reproduce it. Regardless, I think this was a consequence of some intermediate work being done with #10497 that was resolved in some subsequent PRs.
