mvn package failed for service-registry-v8 and v9

[travis-hu-cn]

Error occured while packaging (mvn package) microservices-v9/service-registry: https://github.com/microservices-practical/microservices-v9/tree/master/service-registry.

I noticed the following error message, and I am sure the port 8761 is free by executing "netstat -o | findstr 8761".

Console output has been attached:
service-registry-package.log

I googled and noticed some posts said the application.properties should be :

server.port=8761
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false

after I modified, "mvn package" can pass, but encountered other issues while visiting the ui/index.html.

Please help on this. Thanks a lot !

Hi,

Did you add any further changes to the code or are you using the repository as-is? That error usually happens when the service registry can't register itself. The properties you added tell the service not to register, which should be also fine I guess. What other issues do you get in that case?

This line in the logs seems odd to me:
