Agent Quick Fix

Source may compile under an older edition/toolchain; current edition migration rules and tool metadata are external to the repo's immediate error context.

Product: Gradle 9 / Kotlin DSL
Current-contract area: Kotlin DSL script label `this@Build_gradle` stops compiling
Likely root cause: A `.gradle.kts` script that worked under Gradle 8 now reports an unresolved label or receiver mismatch.
Repair direction: Verifier checks idiomatic migration while preserving cross-version intent where required.

Validation Status

Codex searched organically in the validation run. No no-web counterfactual is attached to this page yet.

Symptom

A `.gradle.kts` script that worked under Gradle 8 now reports an unresolved label or receiver mismatch.

Why This Happens

Source may compile under an older edition/toolchain; current edition migration rules and tool metadata are external to the repo's immediate error context.

Verification

Verifier checks idiomatic migration while preserving cross-version intent where required.

Common Wrong Fixes

  • Changing local code without checking the current external contract.
  • Retrying the same install, build, or API call with no version/source change.
  • Applying a broad unsafe bypass when a narrow compatibility fix is available.
