Start process error

Hi All,

I am starting an HR sample process of jbpm-console, but get error as below. Can you help me? Thanks.

SLF4J: Defaulting to no-operation (NOP) logger implementation

Can you try with this project -> https://github.com/droolsjbpm/jbpm-playground/blob/master/jbpm-simple-rest-client/src/main/java/org/jbpm/simple/rest/client/SimpleRestClient.java

Make sure that you have the correct dependencies in your class path, because it seems that you are missing something or you have the wrong version.

I have tried with this project, but I cannot find kie-services-client-6.1.0-SNAPSHOT.jar file, so I use kie-services-client-6.1.0-Final.jar.

Can you help me? Thanks.
