In the Java ecosystem, we often see different artifacts for the same library, distinguished by a different _classifier_.
A typical example is Guava, which is published as this:

- `guava-jre` for JDK 8 and above
- `guava-android` for JDK 7

The problem with this approach is that there's no semantics associated with the classifier.

This post uses TeamCity bundled with Tomcat servlet container and covers the evaluation setup of a TeamCity server and a default build agent running on the same machine.

. Make sure you have JRE or JDK installed and the JAVA_HOME environment variable is pointing to the Java installation directory. Oracle Java 1.8 JDK is required.
. Download TeamCity .tar.gz distribution.
