Different version of scala lib in the build path and scala -ide

I have two versions of scala (2.11.4 and 2.10.4). I am currently working on a project based on scala 2.10. I changed the version in the project properties, but ide still complains about this:

The version of scala library found in the build path (2.10.4.) Is different from the version of scala IDE (2.11.4.). Make sure you know what you are doing.

I use

Scala IDE Construction Eclipse SDK Build id: 4.0.0-vfinal-20141216-1226-Typesafe

Project Configuration: enter image description here

Any idea how to fix this?

This complaint is a warning, not a mistake; Things are good. I suspect that the message was mostly left after scala -ide was used only to support working with one version of scala in one installation (which was fixed only in version 4.0)

Yes, you can use support for multiple versions of scala, as described in this blog post .

Once properly configured, as you showed in the image, this is just a warning and therefore safe to ignore.
