Description

I'm trying to use camel-etcd which uses etcd4j 2.13.0 in apache camel 2.20.1. Unfortunately the netty versions are incompatible due to a breaking change in io.netty.resolver.dns.DnsAddressResolverGroup
exception is
Caused by: java.lang.NoSuchMethodError: io.netty.resolver.dns.DnsAddressResolverGroup.(Ljava/lang/Class;Lio/netty/resolver/dns/DnsServerAddresses;)V

It appears that the Netty version in the master branch of etcd4j would fix this issue once the maintainers cut a new release. Requested here:
https://github.com/jurmous/etcd4j/pull/146

Once that's done will need to update camel-etcd with the new version.
