如何使用 Firebase 模拟器通过 Firestore 触发器测试 Java 云功能？

Question

I'm trying to use Java11 runtime for Google cloud/firebase functions, which was quite recently released. I want to test firestore trigger functions on my local machine. Guides on the internet seem to be using the command firebase functions:shell which by itself starts the required emulation processes. However, I don't find any method to specify the.jar file for the firebase functions:shell command. Or any way to specify the functions. I know it doesn't load my Java http function because it shows the loaded functions and helloWorld isn't one of them:

gintas-mac:functions gintas$ firebase functions:shell
⚠  Your requested "node" version "10" doesn't match your global version "8"
i  functions: Loaded functions: helloWorld
⚠  functions: The following emulators are not running, calls to these services will affect production: firestore, database, pubsub

Answer 1

It's not possible to use the Firebase CLI to test a function written in Java. Firebase only supports functions written with the firebase-functions module on nodejs.
