无效覆盖，应用程序因 AbstractMethodError 崩溃

Question

我正在为我的应用程序开发类似导航框架之类的东西，现在是一个简单的任务，使超类中的某些容器被其子级覆盖，但是当我向方法并因 AbstractMethodError 崩溃，这看起来不可能。

这是我的课：

abstract class LceScreen<S, VM: LceViewModel<S>>(
    viewModelClass: Class<VM>
): MvvmScreen<LceState<S>, VM>(viewModelClass) {

    @Composable
    final override fun Content(viewModel: VM) {
        SomeFun(vm = viewModel) {
            when (val state = viewModel.state) {
                is Loading -> Loading(
                    viewModel = viewModel
                )

                is Content -> Content(
                    content = state.content,
                    viewModel = viewModel
                )

                is Error -> Error(
                    throwable = state.throwable,
                    viewModel = viewModel
                )
            }
        }
    }

    @Composable
    protected abstract fun SomeFun(vm: VM, content: @Composable () -> Unit)

    @Composable
    protected abstract fun Loading(
        viewModel: VM
    )

    @Composable
    protected abstract fun Content(
        content: S,
        viewModel: VM
    )

    @Composable
    protected abstract fun Error(
        throwable: Throwable,
        viewModel: VM
    )
}

AGP 8.1.0-beta01 KGP 1.8.0 有什么想法，可能有什么问题吗？ 非常感谢！

我尝试清理、重建、删除 build 和 .gradle 文件夹、删除 /.gradle/cache 文件夹

Answer 1

问题是因为无效的全局 gradle 缓存，当我清理它时，一切都变得有效。 要清理全局 gradle 缓存，请使用

rm -rf $HOME/.gradle/caches/
