What causes "No REUSE.toml file found in current directory" in slint-ui/slint?

Run the command from the directory containing REUSE.toml, or ensure the repo root has a REUSE.toml

No REUSE.toml file found in current directory

Error message

No REUSE.toml file found in current directory

What it means

check_reuse_compliance requires a REUSE.toml file in the current working directory, since the xtask REUSE workflow is configured per-directory through REUSE.toml. This bail fires early, before even looking for the reuse binary, when the CWD has no REUSE.toml.

Solutions

Run the command from the directory containing REUSE.toml, or ensure the repo root has a REUSE.toml
Create a REUSE.toml declaring copyright/licensing info (see REUSE specification) if none exists
In CI, verify the checkout preserves REUSE.toml before invoking the xtask

Example fix

// before
cd repo && cargo xtask reuse-compliance-check   # no REUSE.toml in repo/
// after
# add a REUSE.toml at the repo root or cd into the directory that has one
printf 'version = 1\n[[annotations]]\npath = ["**"]\nSPDX-FileCopyrightText = "..."\nSPDX-License-Identifier = "..."\n' > REUSE.toml

Defensive patterns

Strategy: validation

Validate before calling

if !std::path::Path::new("REUSE.toml").is_file() {
    eprintln!("Run from a directory containing REUSE.toml");
    std::process::exit(1);
}

Try / catch

match run_reuse_check() {
    Err(e) if e.to_string().contains("No REUSE.toml") => eprintln!("cd into the licensed directory or create REUSE.toml first"),
    other => other?,
}

Prevention

Run xtask reuse-compliance-check from the directory that owns REUSE.toml
Create a REUSE.toml at the repo root if whole-tree checks are expected
Add REUSE.toml existence to CI setup steps before invoking the check

When it happens

Trigger: Running `cargo xtask reuse-compliance-check` from a directory that does not contain REUSE.toml — typically from the repository root when REUSE.toml only exists in subdirectories, or after the file was deleted/renamed.

Common situations: Executing the xtask from the wrong directory; REUSE.toml not yet created for the project; file renamed (e.g. .reuse/dep5 deprecated layout without REUSE.toml); CI checkout step skipped the file.
