I have the SBT 0.12 installed on my computer, with several plugins but I have seen several projects that are already using the SBT 0.13. How can I have you both on my machine at the same time, without conflict?

In the archive project/build.properties you can add a line with the desired sbt version.

sbt.version=0.12.0

So you can install the latest version of sbt but keep the compatibility of projects that use a previous version.

  • Unfortunately, it doesn’t work. I get an error message "java.lang.Incompatibleclasschangeerror: Found class jline.Terminal, but interface was expected".

    Are you with version 13 installed and setting 12 in the project or the other way around? (Try the first scenario, newer version installed and older version set in properties)
