[JAVA] Rest-assured library not found in versions 3.0.x

Description

I want to generate my Java sdk using the rest-assured library. This was available in 2.4.x but seems to have disappeared in 3.0.x.

Error:

Start by reproducing the reported Maven generation command with swagger-codegen 3.0.5 and compare the Java generator's available libraries with version 2.4.x. Trace how the rest-assured option is registered and verify that generation accepts it and produces the expected Java SDK without the unknown-library error.
