Collection 'smoke_tests' is only available for 'nativeaot'…

Error message

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

What it means

Raised by superpmi_collect_setup.py at src/coreclr/scripts/superpmi_collect_setup.py:654 when collection_name is 'smoke_tests' but collection_type is not 'nativeaot'. The smoke_tests collection is only meaningful for NativeAOT compilation.

Solutions

Set collection_type to 'nativeaot' when using collection_name 'smoke_tests'.
If you need a non-NativeAOT smoke run, choose a different collection_name that supports it.

Example fix

// before
collection_name: smoke_tests
collection_type: crossgen2
// after
collection_name: smoke_tests
collection_type: nativeaot

Defensive patterns

Strategy: validation

Validate before calling

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

Prevention

Cross-check collection_name against its allowed collection_type in the pipeline YAML before submitting.

When it happens

Trigger: Configuring a superpmi collection with collection_name=smoke_tests together with collection_type=crossgen2 (or any non-nativeaot type).

Common situations: YAML pipeline misconfiguration that reuses a crossgen2 collection_type block for the smoke_tests collection.
