Error with fresh setup of stable version #1036

[iamsanjay97]

Please see issue #1036. I'm still facing the same problem.

I am able to run sample-broker 1.7.0 without any problem with 1.7 version of server.

But I'm getting the same error while running sample-broker 1.6.0 with Power TAC distribution 1.7.0-SNAPSHOT. Our broker is built upon sample-broker 1.6.0 , so it is also throwing the same error.

I tried local install of powertac-core as you said in one of the comments, but it didn't help.

Software Configurations:
JAVA : java version "11.0.5" 2019-10-15 LTS
Maven : Apache Maven 3.6.0

Kindly help me to resolve this issue.

There appears to be an incompatible mismatch in the Apache MQ setup between the 1.6.0 and 1.7.0-SNAPSHOT versions of the server. But your broker is in source form; it works to just tell it to use the 1.7.0-SNAPSHOT version of broker-core and its dependencies. You can do that by editing sample-broker/pom.xml, changing the string 1.6.0 to 1.7.0-SNAPSHOT in two places. I have tested this with a fresh download of the sample-broker 1.6.0 source.

Please let us know if this solves your problem.

Thanks for quick reply.

That worked. Now I'm able to run our brokers with server 1.7 with Java11.

But I have broker binaries of other brokers (.jar files), how to make them run in this setting ?

I'm working on that. Ideally it could be handled on the server, but might require editing a config file in the broker.

Okay. Thanks for your help.
