[GitHub] [arrow-cookbook] iamsmkr opened a new issue, #199: [Java] Link to install instructions (was: Cannot resolve io.netty:netty-transport-native-unix-common:4.1.72.Final)

[GitBox]

iamsmkr opened a new issue, #199:
URL: https://github.com/apache/arrow-cookbook/issues/199

   I thought of trying the example from the cookbook java 
(https://arrow.apache.org/cookbook/java/flight.html) but I keep getting the 
following exception when building the project
   ```
   Cannot resolve io.netty:netty-transport-native-unix-common:4.1.72.Final 
   ```
   
   Since the cookbook doesn't list out the dependencies explictly in the doc I 
copied from 
https://github.com/apache/arrow/blob/master/java/flight/flight-integration-tests/pom.xml.
 Although it would be really nice if the docs specify the dependencies clearly.
   
   My pom.xml look is like this:
   ```xml
   <?xml version="1.0" encoding="UTF-8"?>
   <project xmlns="http://maven.apache.org/POM/4.0.0";
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";

   Please suggest how could I resolve this problem?
