How to check sbt version?

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 by Steffen for How to check sbt version?

$ 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 what 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.

Answer by Jacek Laskowski for How to check sbt version?

In SBT 0.13 and above, you can use the sbtVersion task (as pointed out by @steffen) or about command (as pointed out by @mark-harrah)

There's a difference how the sbtVersion task works in and outside a SBT project. When in a SBT project, sbtVersion displays the version of SBT used by the project and its subprojects.

$ sbt sbtVersion  [info] Loading global plugins from /Users/jacek/.sbt/0.13/plugins  [info] Updating {file:/Users/jacek/.sbt/0.13/plugins/}global-plugins...  [info] Resolving org.fusesource.jansi#jansi;1.4 ...  [info] Done updating.  [info] Loading project definition from /Users/jacek/oss/scalania/project  [info] Set current project to scalania (in build file:/Users/jacek/oss/scalania/)  [info] exercises/*:sbtVersion  [info]  0.13.1-RC5  [info] scalania/*:sbtVersion  [info]  0.13.1-RC5  

It's set in project/build.properties:

jacek:~/oss/scalania  $ cat project/build.properties  sbt.version=0.13.1-RC5  

The same task executed outside a SBT project shows the current version of the executable itself.

jacek:~  $ sbt sbtVersion  [info] Loading global plugins from /Users/jacek/.sbt/0.13/plugins  [info] Updating {file:/Users/jacek/.sbt/0.13/plugins/}global-plugins...  [info] Resolving org.fusesource.jansi#jansi;1.4 ...  [info] Done updating.  [info] Set current project to jacek (in build file:/Users/jacek/)  [info] 0.13.0  

When you're outside, the about command seems to be a better fit as it shows the sbt version as well as Scala's and available plugins.

jacek:~  $ sbt about  [info] Loading global plugins from /Users/jacek/.sbt/0.13/plugins  [info] Set current project to jacek (in build file:/Users/jacek/)  [info] This is sbt 0.13.0  [info] The current project is {file:/Users/jacek/}jacek 0.1-SNAPSHOT  [info] The current project is built against Scala 2.10.2  [info] Available Plugins: com.typesafe.sbt.SbtGit, com.typesafe.sbt.SbtProguard, growl.GrowlingTests, org.sbtidea.SbtIdeaPlugin, com.timushev.sbt.updates.UpdatesPlugin  [info] sbt, sbt plugins, and build definitions are using Scala 2.10.2  

You may want to run 'help about' to read its documentation:

jacek:~  $ sbt 'help about'  [info] Loading global plugins from /Users/jacek/.sbt/0.13/plugins  [info] Set current project to jacek (in build file:/Users/jacek/)  Displays basic information about sbt and the build.  

For the sbtVersion setting, the inspect command can help.

$ sbt 'inspect sbtVersion'  [info] Loading global plugins from /Users/jacek/.sbt/0.13/plugins  [info] Set current project to jacek (in build file:/Users/jacek/)  [info] Setting: java.lang.String = 0.13.0  [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:67  [info] Delegates:  [info]  *:sbtVersion  [info]  {.}/*:sbtVersion  [info]  */*:sbtVersion  [info] Related:  [info]  */*:sbtVersion  

The version setting that people seem to expect to inspect to know the SBT version is to set The version/revision of the current module.

$ sbt 'inspect version'  [info] Loading global plugins from /Users/jacek/.sbt/0.13/plugins  [info] Set current project to jacek (in build file:/Users/jacek/)  [info] Setting: java.lang.String = 0.1-SNAPSHOT  [info] Description:  [info]  The version/revision of the current module.  [info] Provided by:  [info]  */*:version  [info] Defined at:  [info]  (sbt.Defaults) Defaults.scala:102  [info] Reverse dependencies:  [info]  *:projectId  [info]  *:isSnapshot  [info] Delegates:  [info]  *:version  [info]  {.}/*:version  [info]  */*:version  [info] Related:  [info]  */*:version  

When used in a SBT project the tasks/settings may show different outputs.

You can use sbt about

  Example:       C:\Users\smala>sbt about      [info] Set current project to smala (in build file:/C:/Users/smala/)      [info] This is sbt 0.13.6      [info] The current project is {file:/C:/Users/smala/}smala 0.1-SNAPSHOT      [info] The current project is built against Scala 2.10.4      [info] Available Plugins: sbt.plugins.IvyPlugin, sbt.plugins.JvmPlugin,   sbt.plugins.CorePlugin, sbt.plugins.JUnitXmlReportPlugin      [info] sbt, sbt plugins, and build definitions are using Scala 2.10.4"

Answer by morganw09dev for How to check sbt version?

Running the command, "sbt sbt-version" will simply output your current directory and the version number.

$ sbt sbt-version  [info] Set current project to spark (in build file:/home/morgan/code/spark/)  [info] 0.13.8
