setting correct scala version on scala ide

I'm trying to work on a project on scala IDE but I've having build problems on scala IDE.
On sbt the project builds fine. I used the eclipse sbt plugin and imported the project on scala IDE. There were build errors, which makes the ide close to useless.
One of the errors is Compiler plugin paradise_2.12.1-2.1.0.jar is cross-compiled with incompatible version for this project: 2.12.1 vs 2.12.2
I thought scala minor versions were compatible, though I see there is an exception for some experimental modules. Is the macro paradise plugin one of those exceptions?
How can I fix it? Can I tell scala IDE to use 2.12.1? Shouldn't the sbt eclipse plugin take care of that? Should I report a bug(to which project)?
The project on which I'm working defines scala version to be "2.12.1", but I'd rather not change it. I'm using scala ide version 4.6.1.
