If you're using binding extensions (e.g. Azure Storage, ServiceBus, Timers, etc.) make sure you've called the registration method for the extension(s) in your startup code (e.g. builder.AddAzureStorage(), builder.AddServiceBus(), builder.AddTimers(), etc.).

Azure function built successfully and exists in expected hierarchy folders under target.

Reproduce the report with Azure Functions Core Tools and its --verbose option, using the supplied pom.xml, HttpTriggerFunction.java, host.json, and local.settings.json. Check how the local project is built and discovered, then verify that the echo function is detected without the “No job functions found” message.
