I saw many messages about Spring Roo console in IntelliJ, but can't find any traces of Roo in reality:
Where is it? Or what is instead of it?
Nowadays, the Spring Roo shell is beeing maintained by DISID and the only official tool tested to work with Spring Roo 2.0.0.RC1 is the Spring Tool Suite (STS).
If you're interested about how to work with Spring Roo using the STS IDE, follow the Spring Roo documentation about how to include the Spring Roo plug-in into your STS distribution.

On the other hand, I found some (really old) posts about Spring Roo and IntelliJ:
https://blog.jetbrains.com/idea/2011/04/new-in-105-spring-roo-console/ https://www.jetbrains.com/help/idea/13.0/working-with-spring-roo-console.pdf
But as I've said before, this is not the official and maintained tool to work with the Spring Roo shell.
Hope it helps,
