Regression: 2.40.2 generates invalid code: variable is already defined in method

[bubenheimer]

The Kotlin code below generates invalid code in 2.40.2; works fine in 2.39.1 and prior:

    class LifecycleTracker @AssistedInject internal constructor(
        @Assisted lifecycle: Lifecycle,
        private val analytics: FirebaseAnalytics,
        @Assisted private val myName: String
    ) : DefaultLifecycleObserver {
        @AssistedFactory
        sealed interface Factory {
            operator fun Lifecycle.invoke(myName: String): LifecycleTracker
        }

        // ...
    }

This generates the following Java code, which has a duplicate variable name in the invoke method; looks related to using a receiver instead of a parameter for Lifecycle:

    @DaggerGenerated
    @Generated(
        value = "dagger.internal.codegen.ComponentProcessor",
        comments = "https://dagger.dev"
    )
    @SuppressWarnings({
        "unchecked",
        "rawtypes"
    })
    public final class LifecycleTracker_Factory_Impl implements LifecycleTracker.Factory {
        private final LifecycleTracker_Factory delegateFactory;

        LifecycleTracker_Factory_Impl(LifecycleTracker_Factory delegateFactory) {
            this.delegateFactory = delegateFactory;
        }

        @Override
        public LifecycleTracker invoke(Lifecycle myName, String myName) {
            return delegateFactory.get(myName, myName);
        }

        public static Provider<LifecycleTracker.Factory> create(
                LifecycleTracker_Factory delegateFactory) {
            return InstanceFactory.create(new LifecycleTracker_Factory_Impl(delegateFactory));
        }
    }

The build error is variable myName is already defined in method invoke

In 2.39.1 the generated variable name for the receiver in the generated invoke method is $this$invoke.

Thanks, I was able to repro this! Looking into it now.

FYI, this should be fixed now but I likely won't get a release out until Monday.
