#19731 `run_shell_command(runnable_dependencies=[...])`s are not runnable Issue created by huonw Describe the bug The

runnable_dependencies

field is documented as "Note that these dependencies will be made available on the PATH with the name of the target." https://www.pantsbuild.org/docs/reference-run_shell_command This doesn't seem to work for `run_shell_command`: the command's

$PATH

is identical to that of the ambient shell that's running

pants

, and the targets cannot be executed, unlike

shell_command

. Reproducer:

cd $(mktemp -d)

cat > pants.toml <<EOF
[GLOBAL]
pants_version = "2.16.0"
backend_packages.add = ["pants.backend.shell", "pants.backend.python"]

[python]
interpreter_constraints = ["==3.10.*"]

[anonymous-telemetry]
enabled = false
EOF

cat > BUILD <<'EOF'
python_source(name="some-script", source="some_script.py")

shell_command(
    name="shell_command",
    command="echo PATH=$PATH; some-script",
    runnable_dependencies=[":some-script"],
    log_output=True,
)
run_shell_command(
    name="run_shell_command",
    command="echo PATH=$PATH; some-script",
    runnable_dependencies=[":some-script"],
)
EOF

echo 'print(f"hello from {__file__}")' > some_script.py

# GOOD: the shell_command can run the script and prints the hello (plus a limited $PATH):
pants export-codegen :shell_command
#> PATH=/private/.../pants-sandbox-.../_binary_shims_...:/private/.../pants-sandbox-.../_runnable_dependency_shims_...
#> hello from /private/.../pants_sandbox-..././some_script.py

# for reference, what's the ambient path?
echo "ambient PATH=$PATH"
# BUG: the run_shell_command has the same $PATH as above , and cannot run `some-script`
pants run :run_shell_command
#> PATH=<same as ambient>
#> some-script: command not found

The output is like, for example:
