[L_DisplayName]

Greetings All,
I am receiving the following error when I execute the command: mvn clean package within Netty In Action's chapter 2 book code as follows:
/netty-in-action-2.0-SNAPSHOT/chapter2# mvn clean package

I am using maven version 3.3.9 and oracle java version 1.8.0. Both maven and java were added to my executable PATH.  In addition, I downloaded the latest book code from: https://github.com/normanmaurer/netty-in-action/tree/2.0-SNAPSHOT

Can someone tell me how I can resolve this issue and why maven can not find the artifact: nia:utils:jar:2.0-SNAPSHOT?

You need to build "utils" module first. Try run "mvn clean install" from the top level "netty-in-action" folder first.
