TL;DR: firebase-admin and firebase-messaging has the same classpath com.google.firebase.messaging.*, but their class's content is totally different.
Currently, I want to use both the module firebase-admin and firebase-messaging to learn about the feature Cloud Messaging, so I have installed my dependencies as above. The issue arose when I wanted to import the class FirebaseMessaging.
// Create a list containing up to 500 registration tokens.
// These registration tokens come from the client FCM SDKs.
List<String> registrationTokens = Arrays.asList(
"YOUR_REGISTRATION_TOKEN_1",
// ...
"YOUR_REGISTRATION_TOKEN_n"
);
MulticastMessage message = MulticastMessage.builder()
.putData("score", "850")
.putData("time", "2:45")
.addAllTokens(registrationTokens)
.build();
BatchResponse response = FirebaseMessaging.getInstance().sendMulticast(message);
// See the BatchResponse reference documentation
// for the contents of response.
System.out.println(response.getSuccessCount() + " messages were sent successfully");
It turned out that while the imported class was com.google.firebase.messaging.FirebaseMessaging, the class was from the module firebase-messaging , which did not contain any of useful send method, rather than firebase-admin.
Is there anyway I can import the class FirebaseMessaging from firebase-admin and still keeping the two modules? I had switching the import order in Gradle file but still to no avail.
Environment
This is currently the dependencies used in my app-level Gradle build script
