Running cargo clippy in Makefile tries to install cargo-clippy crate

[Marcono1234]

Hello,
I have a repository with rust-toolchain.toml file and upgraded to the toolchain 1.78.0. The problem is that builds with my cargo-make Makefile fail on CI now:

...
[cargo-make] INFO - Running Task: clippy
[cargo-make] INFO - Execute Command: "cargo" "install" "cargo-clippy"
Updating crates.io index
error: could not find cargo-clippy in registry crates-io with version *
[cargo-make] ERROR - Error while executing command, exit code: 101
[cargo-make] WARN - Build Failed.

(GitHub actions log)

For whatever reason it does not use the official cargo clippy but tries to install a crate called cargo-clippy. Do you have any idea what is causing this? Or whether cargo-make or cargo is performing this incorrect cargo install?

Sorry if the error is completely obvious, or I am misunderstanding cargo-make or cargo behavior.

I thought if I adjust rust-toolchain.toml and then run any cargo command it would automatically download the needed toolchain and components, and so far it seems that worked fine for me in the past for other toolchain versions. And also for 1.78.0 it looks like it worked locally for me without any issues (but maybe I had executed another cargo command before running cargo make).

• Am I misunderstanding how rust-toolchain.toml works or how cargo-make interacts with it?
• Am I misunderstanding the Makefile.toml syntax, or is my Makefile.toml error-prone or ambiguous?

My GitHub workflow was previously using cargo-make 0.37.2; I have now updated to cargo-make 0.37.11 and that seems to have solved it¹.

Was there a change in cargo-make in the latest versions which has fixed this? Or is my Makefile or setup still faulty, and it just happens to work now for whatever reason.

Footnotes

1. After some more testing, it looks like upgrading from cargo-make 0.37.6 to 0.37.7 fixed the GitHub workflow failure. ↩

i do'nt remember a change specific to clippy

I have tested a bit more, and it does not seem to be specific to clippy; if I reorder the tasks I get a similar issue for cargo fmt as well (but interestingly not for cargo doc):

...
[cargo-make] INFO - Running Task: format-check
[cargo-make] INFO - Execute Command: "cargo" "install" "cargo-fmt"
Updating crates.io index
error: could not find cargo-fmt in registry crates-io with version *

For 0.37.7 your release notes say "Detect crate installation fix for new cargo list format" (and some of your commits for that version say "cargo plugin detection fix"). Could that maybe be the reason why this was solved in that version?
Though I am not familiar with what exactly this line in the release notes refers to, respectively what has changed for cargo in recent versions and why this fix was needed. If possible, could you please share some details about this?

Or do you notice that something is in general wrong with my setup of using rust-toolchain.toml in combination with cargo-make?
