NoSuchMethodError with v2.2.0

[sebakerckhof]

I try to connect the monitor to my zeebe instance (zeebe 1.2.8 and hazelcast exporter 1.0.1).
This works with simple-monitor v 2.0.0 and 2.1.0, but fails with 2.2.0, where every action I take in the monitor (e.g. deploying diagram, sending a message, ...) results in the following error:

@sebakerckhof thank you for reporting 👍
I can reproduce the issue. I will check why it is failing in version 1.2.0 🤔

There is a dependency conflict with com.google.protobuf:protobuf-java.

+- io.camunda:spring-zeebe-starter:jar:1.2.8:compile
|  \- io.camunda:spring-zeebe:jar:1.2.8:compile
|     +- io.camunda:zeebe-client-java:jar:1.2.9:compile
|     |  +- com.google.protobuf:protobuf-java:jar:3.18.0:compile

+- io.zeebe.hazelcast:zeebe-hazelcast-connector:jar:1.0.1:compile
|  \- io.zeebe:zeebe-exporter-protobuf:jar:1.0.0:compile
|     \- com.google.protobuf:protobuf-java:jar:3.15.6:compile

I need to release a new version of zeebe-exporter-protobuf and zeebe-hazelcast-connector to fix the dependency issue.
