java - 函数运行时无法启动 - 无法加载类型 'Microsoft.Azure.ServiceBus.Management.ManagementClient'

Question

我部署了基于 Java 的新版本的 Azure Functions。现在，在特定函数中我的 Azure 函数资源下的 Azure 门户中出现以下错误 toast:

Error: The function runtime is unable to start. Microsoft.Azure.WebJobs.ServiceBus: Could not load type 'Microsoft.Azure.ServiceBus.Management.ManagementClient' from assembly 'Microsoft.Azure.ServiceBus, Version=3.0.2.0, Culture=neutral, PublicKeyToken=7e34167dcc6d6d8c'. Session Id: a9f3c42dbb524ceca2c5158df9460c97 Timestamp: 2019-12-02T18:21:46.680Z

对我来说听起来有点像:https://github.com/Azure/azure-functions-host/issues/3363

有趣的是，直到最后一次部署，除了一些小的 Java 代码更改之外，我没有进行任何更改。 Function App 版本会自动更新吗？

我还通过 kudu 和日志流(应用程序日志)检查了日志。

日志流:

与通过 kudu 的日志文件中的日志相同

你知道它为什么停止工作吗？老实说我没有计划。服务总线的任何配置是否触发更改？

在 Azure 门户中检查解决方案 对于生产中的问题，请在提出错误之前在 Azure 门户中检查常见问题的解决方案。在 Azure 门户中，导航到函数应用 => 平台功能 => 诊断和解决问题以及相关仪表板，然后再提出问题。

调查信息 请提供以下信息:

时间戳:2019-12-02T18:21:46.680Z 函数应用版本(1.0 或 2.0):2.0.12888.0 (~2) 函数应用程序名称:functionapp-dtw-worker-dp-master 应用设置: FUNCTIONS_WORKER_RUNTIME:java 函数名称(视情况而定):serviceBusProcessor session ID:a9f3c42dbb524ceca2c5158df9460c97 地区: 西欧 相关信息 提供任何相关信息

使用的编程语言:Java with Spring Boot、Spring Cloud Functions 来源链接 使用的绑定(bind):ServiceBusTrigger、TimeTrigger

补充:我从此处将 .NET Core 版本等本地依赖项更新为最新的 v2.2.8:https://dotnet.microsoft.com/download/dotnet-core/2.2

更新不会更改错误消息。当我在本地使用 Maven 插件“azure-functions-maven-plugin”版本 1.3.4 启动该函数时，出现相同的错误异常，如下所示:

您对解决这些问题有什么建议吗？

Answer 1

部署似乎以某种方式删除了已安装的扩展。从 VSCode 部署后，我刚刚遇到了与 TS 函数相同的错误。作为解决方法，我开始使用与应用程序中其他函数相同的模板(例如 Azure 服务总线主题触发器)在同一函数应用程序中创建新函数。就我而言，这触发了所需扩展的新安装，并且错误消失了。
