Language edition/toolchain drift
Gradle 9 Kotlin DSL unresolved label this@Build_gradle Kotlin 2 K2 script label
A `.gradle.kts` script that worked under Gradle 8 now reports an unresolved label or receiver mismatch.
Agent Quick Fix
Repair against the current Gradle 9 / Kotlin DSL contract, then keep the change narrow and source-backed.
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.
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.
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.
