Silvertip is a networking library, which aims to be easy to use, while hiding the complexities of the Java NIO API. While similar libraries exist, they are either hard to use, discontinued, or part of a bigger application framework that offer an API for using different transports.
Add a dependency to Silvertip:
<dependency>
<groupId>silvertip</groupId>
<artifactId>silvertip</artifactId>
<version><!-- (latest version) --></version>
</dependency>
Because Silvertip is not available in the Central Repository, you need to add Silvertip's repository as well:
<repository>
<id>valotrading</id>
<url>http://valotrading.github.io/maven</url>
</repository>
