• 这主要是由于Azure功能核心工具的问题。
• 虽然您已升级Azure功能核心工具，但请尝试完全卸载功能核心工具，然后重新安装。

1. npm ls -g azure-functions-core-tools
2. npm uninstall -g func
3. npm install -g azure-functions-core-tools --unsafe-prem true

• Java和Maven。
• 删除项目的bin文件夹，然后清理并重建应用程序。
• 确保您在pom.xml中具有所有兼容版本所需的依赖项：

• • 如果问题仍然存在，请尝试创建新的示例Azure函数，并检查是否出现相同的错误。
