flutter - 为什么在 dart/flutter 中序列化 JSON 时 build_runner 不生成文件

Question

我只是想用我 3 个月前存储的相同命令来生成我的文件(我对后端和 devops 不太擅长)，现在它不再生成文件了。
它告诉我使用我不记得的删除命令，但即使使用该命令，我的文件仍然不会生成。
这就是我的日志的样子，您可以在下面找到一个简单类的代码。

我的猜测之一是这与我更改 github 帐户有关，因为提到了权限问题。

我在 Windows 10 中使用 vs 代码。

日志文件:

[SEVERE] Conflicting outputs were detected and the build is unable to prompt for permission to remove them. These outputs must be removed manually or the build can be run with `--delete-conflicting-outputs`. The outputs are: lib/models/advisory-service-item.g.dart

类文件:

import 'package:json_annotation/json_annotation.dart';
part 'organisation.g.dart';

@JsonSerializable()
class Organisation {
  final String name;
  Organisation({this.name});

  factory Organisation.fromJson(Map<String, dynamic> json) => _$OrganisationFromJson(json);

  Map<String, dynamic> toJson() => _$OrganisationToJson(this);
}

我有一个类似的问题，但我使用的是 Android Studio IDE，我已经完成了以下步骤:

文件 => 使缓存无效/重新启动

运行以下命令:

flutter clean

flutter pub get

flutter packages pub run build_runner build --delete-conflicting-outputs
