Issue connecting to remote consul endpoint

[sashkachan]

Consul is located at: http://172.17.0.77:8500

I set up the Consul with:

consul = Consul.builder().withUrl("http://172.17.0.77:8500").build();

I get an exception thrown:

SEVERE: java.lang.NullPointerException : null

Not sure if webTarget is null?
I used gradle dependencies from the readme file.

    compile 'com.orbitz.consul:consul-client:0.9.15'
    // include your preferred javax.ws.rs-api implementation, for example:
    compile 'org.apache.cxf:cxf-rt-rs-client:3.0.3'
    compile 'org.apache.cxf:cxf-rt-transports-http-hc:3.0.3'

Thanks!

I'm having a hard time reproducing. Let me dig around in the CXF code and see if I can figure out what is causing this.

Do you have any other JAX-RS implementations on the classpath?

[rickfast]

I just tried this with the same cxf version using withUrl

Consul client = Consul.builder().withUrl("http://192.168.99.100:8500").build();
Agent agent = client.agentClient().getAgent();

[rickfast]

I just released 0.9.16. Try that and let me know if you still have problems

Thanks for the quick feedback.
I did a test run on an empty project and could successfully connect to the endpoint.
Something with my code. I will close for now. Thank you.

I had similar issue and the problem was CXF and shade plugin
