Error message

Collection 'smoke_tests' is only available for 'nativeaot' collections.

What it means

Raised in superpmi_collect_setup.py main() when collection_name=='smoke_tests' but collection_type != 'nativeaot'. The smoke_tests collection is implemented only for the native AOT compilation path.

Solutions

1. Set collection_type to 'nativeaot' when using smoke_tests.
2. If you need a JIT-style collection, pick a collection_name supported by your collection_type.
3. Add an explicit argument-validation matrix in your YAML to keep name/type consistent.

Example fix

// before
# --collection_name smoke_tests --collection_type coreclr -> raises [193]
// after
--collection_name smoke_tests --collection_type nativeaot

if collection_name == 'smoke_tests' and collection_type != 'nativeaot':
    raise SystemExit("smoke_tests requires collection_type=nativeaot")

def collection_combo_valid(name: str, ctype: str) -> bool:
    return name != 'smoke_tests' or ctype == 'nativeaot'

try:
    main(args)
except RuntimeError as e:
    if 'smoke_tests' in str(e):
        args.collection_type = 'nativeaot'; main(args)

When it happens

Trigger: Pipeline/job sets collection_name=smoke_tests while collection_type is 'coreclr','crossgen2', etc.

Common situations: Copy-pasted a smoke_tests job but left collection_type from a JIT scenario; renaming a collection without updating its type.
