Description

rust-analyzer version: rust-analyzer 0.3.1238-standalone (61504c8d9 2022-10-08)

rustc version: rustc 1.64.0 (a55dd71d5 2022-09-19)

Opening this project (https://github.com/wireapp/core-crypto) I'm running into the following errors:

[ERROR project_model::workspace] cyclic deps: mls_crypto_provider(CrateId(223)) -> core_crypto_keystore(CrateId(98)), alternative path: core_crypto_keystore(CrateId(98)) -> mls_crypto_provider(CrateId(223))
[ERROR project_model::workspace] cyclic deps: mls_crypto_provider(CrateId(223)) -> mls_crypto_provider(CrateId(223)), alternative path: mls_crypto_provider(CrateId(223))
[ERROR flycheck] Flycheck failed to run the following command: "cargo" "clippy" "--workspace" "--message-format=json" "--manifest-path" "/Users/augusto/projects/core-crypto/Cargo.toml" "--all-targets" "--all-features"
[ERROR rust_analyzer::lsp_utils] cargo check failed

Cargo watcher failed, the command produced no valid metadata (exit code: ExitStatus(unix_wait_status(25856))):
error: -Zbuild-std requires --target

[ERROR rust_analyzer::lsp_utils] rust-analyzer failed to run build scripts

error: -Zbuild-std requires --target

I could reproduce it in neovim and in vscode. The cyclic deps error are dev-dependencies and I think this is reported already.

Research direction

Reproduce the report with the core-crypto project in Neovim or VS Code, then trace the reported paths through project_model::workspace, flycheck, and the cargo watcher. Determine whether the cyclic dependency and -Zbuild-std errors are separate failures; done means the project produces valid metadata and no longer reports the build-script failures.
