Gradle 8.14 bundles Kotlin 2.x which enforces stricter type inference. Without explicit annotations, the `tasks.register` lambda parameter and `project.exec` lambda parameter can't be inferred, causing "Variable expected" and "Closure was expected" compile errors respectively. https://claude.ai/code/session_01AJYvT4hqhYe9HZfGnbX5Eg
Gradle 8.14 ships Kotlin 2.x which has stricter type inference and uses receiver lambdas (T.() -> Unit) everywhere in the DSL instead of explicit-parameter lambdas. Three changes required: - ObserverPlugin: rename local `extension` to `ext` to avoid the name clash with ObserverTask.extension inside the receiver lambda, and use the trailing-lambda receiver form for tasks.register so Kotlin resolves the Action overload cleanly. - ObserverPlugin: switch task.reportFile assignment to .set() because abstract val properties cannot be directly reassigned. - ObserverTask: replace deprecated project.exec (whose Groovy Closure overload wins overload resolution in Kotlin 2.x) with an injected ExecOperations service, which exposes only the Action/receiver-lambda overload of exec. https://claude.ai/code/session_01AJYvT4hqhYe9HZfGnbX5Eg
