emitter-io / java Goto Github PK

This won't compile with the current version of maven/Java because the version of maven is too far out of date. If I update the dependencies in the pom.xml, I get an error from the (apparently-now-unsupported?) proguard-maven-plugin:
Failed to execute goal com.github.wvengen:proguard-maven-plugin:2.0.14:proguard (default) on project emitter: Obfuscation failed (result=1)

I am currently evaluating emitter.io as an alternative to deepstream which has some outdated and buggy client SDKs, especially when it comes to Java/Android.

First, I was very happy when I read about the concepts of emitter.io and excited to give it a try. But now that I see this 4 year old Java SDK I am really frustrated. :-( It cannot be integrated in Android as a simple Gradle dependency, the API seems to be outdated compared to the Javascript SDK, it only has 4 stars (???), ...

All in all, this does not seem worth an evaluation at all.

And again (like with deepstream) I am asking myself WHY IS THIS? Why are you obviously not caring about Java/Android? Or am I missing something?

Are there any plans for updating this SDK?

When Qos is AT_MOST_ONCE , connection.publish() is blocked all the time.
I found class CallbackConnection line 699.

private void send(Acked command, Callback cb) {
    short id = 0;
    //if(command.qos() != QoS.AT_MOST_ONCE) {
        id = getNextMessageId();
        command.messageId(id);
   // }
    send(new Request(id, command.encode(), cb));
}

remove the "//", problem solved。

Looking forward to your reply，thank you。
