.net core NopCommerce插件内置于自定义插件中

我正在使用Nopcommerce 4.2并尝试创建一个自定义插件

在运行时，我得到一个错误：

System.Exception: 'A plugin with 'DiscountRequirement.MustBeAssignedToCustomerRole' system name is already defined

当我转到Nop.Web/Plugins时，我可以看到所有已经构建的插件，包括我的。当我查看我的自定义插件时，我可以看到一个名为Plugins的文件夹，其中包含所有已构建的其他插件

我查看了我的csproj，并将其与nop默认插件进行了比较，但无法找出为什么我的csproj会再次构建所有插件

要明确创建的结构是：

不，网络

• 插件/
  --顾客折扣
  --ExchangeRate.ecbeexchange
  --…其他插件
  --我的.插件/
  ----应用程序数据
  ----区域
  ----插件/
  -----顾客折扣
  -----ExchangeRate.ecbeexchange
  -----…其他插件

请清理您的垃圾箱并删除此“Nop.Web->Plugins”文件夹下的所有插件一次。这对我有用。

谢谢

有几个地方出现了错误。未经检查无法给出答案，如plugin.json、dependencyregister.cs、plugin.cs等

但当你熟悉它时，你可以找到自己的加速方式 你的发展

提示：如果您的插件仍然存在任何问题，这是最简单的方法。

只需复制一个小的原始插件，比如'Nop.plugin.Payments.Qualpay，Square，SendinBlue'，然后重命名edit.proj文件集输出文件夹

删除除“DependencyRegister.cs、RouteProvider.cs、plugin.json、StartUpPlugin.cs”之外的所有不必要的类、文件和文件夹

更改其余文件的名称空间并删除不必要的代码

在plugin.json中的“SupportedVersions”：[“4.20”]是一个必须值

构建并清除所有错误

它应该出现在“配置>本地配置”上

提示：这是当我收到参考错误时我的项目构建最佳实践

清洗溶液

转到~/API/Presentation/Nop.Web/Plugins文件夹并删除所有构建文件夹

右键单击“库”文件夹并构建它

右键单击“演示文稿”文件夹并构建它

右键单击“插件”文件夹并构建它

祝你好运 您可以参考以下模板

plugin.json（“SupportedVersions”）：[“4.20”]是一个必须值，否则插件服务将不会选择您的插件

问题可能是引用，因为当您将引用DiscountRequest.MustbeaAssignedTocustomerRole添加到另一个插件时，需要将属性Copylocal=false放入。

确保

plugin.json

中的

系统名

（位于插件文件夹中）是唯一的。你能显示你的plugins.json文件吗？@H.Herzl我已经按要求添加了内容。你需要显示你的plugins.json，这个文件在App_数据中directory@H.Herzl我已经更新了帖子。我从没想过往里面看，但我什么也没看到
