How to check sbt version?

Question

How do I check which version of sbt I'm running?

I have the bash file set up that uses sbt-launch.jar, and it works, but

$ sbt version 

only shows the "project version" (0.1) and

$ sbt --version 

does nothing.

Answer 1

$ sbt sbtVersion 

This prints the sbt version used in your current project, or if it is a multi-module project for each module.

$ sbt 'inspect sbtVersion' [info] Set current project to jacek (in build file:/Users/jacek/) [info] Setting: java.lang.String = 0.13.1 [info] Description: [info]  Provides the version of sbt.  This setting should be not be modified. [info] Provided by: [info]  */*:sbtVersion [info] Defined at: [info]  (sbt.Defaults) Defaults.scala:68 [info] Delegates: [info]  *:sbtVersion [info]  {.}/*:sbtVersion [info]  */*:sbtVersion [info] Related: [info]  */*:sbtVersion 

You may also want to use sbt about that (copying Mark Harrah's comment):

The about command was added recently to try to succinctly print the most relevant information, including the sbt version.
