I'm using cargo-make to collect profile data for code coverage analysis from a rust project in a cargo workspace. I crated this makefile in the workspace directory.
Makefile.toml
[env]
CARGO_MAKE_EXTEND_WORKSPACE_MAKEFILE = true
CARGO_MAKE_WORKSPACE_SKIP_MEMBERS = ["calc_engine_function_lib"]
COV_DIRECTORY = "${CARGO_MAKE_WORKSPACE_WORKING_DIRECTORY}/target/coverage"
[tasks.cov-test]
env = { "CARGO_INCREMENTAL"="0", "RUSTFLAGS"="-Cinstrument-coverage", "LLVM_PROFILE_FILE"="${COV_DIRECTORY}/coverage-%p-%m.profraw" }
command = "cargo"
args = ["test" ]
[tasks.cov-merge]
command = "llvm-profdata"
args = ["merge", "-sparse", "${COV_DIRECTORY}/*.profraw", "-o", "${COV_DIRECTORY}/coverage.profdata"]
[tasks.cov]
dependencies = [
"clean",
"cov-test",
"cov-merge"
]
Here's what I get...
~/dev/calc_engine_workspace % cargo make cov
...

Reset to default 0The problem is that glob expansion (i.e. going from *.profraw to a list of a.profraw b.profraw…) is ususally done by the shell. Here you don't have a shell, so llvm-profdata is looking for a file that is named literally *.profraw.
One easy way to work around the issue is to pass the command to a shell for execution, i.e. something like this:
[tasks.cov-merge]
command = "/bin/sh"
args = [ "-c", "llvm-profdata merge -sparse ${COV_DIRECTORY}/*.profraw -o ${COV_DIRECTORY}/coverage.profdata" ]
