输入“sbt about”，然后回车，得到sbt版本:

sbt --version

它现在的版本为1.3.3+(归功于@ElectronWill)。

你可能还想使用sbt(复制Mark Harrah的评论):

最近添加了about命令，以尝试简洁地打印 最相关的信息，包括SBT版本。

运行命令"sbt sbt-version"将简单地输出您的当前目录和版本号。

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

最新版本的SBT终于支持标准版本标志!

$ sbt --version

sbt version in this project:    1.6.2
sbt script version: 1.6.2

(用1.6+测试，但似乎至少从1.3.3开始就存在了)

从sbt外壳内部

sbt:venkat> about
[info] This is sbt 1.3.3
...

在SBT 0.13及以上版本中，您可以使用sbtVersion任务(由@steffen指出)或about命令(由@mark-harrah指出)

在SBT项目内部和外部，sbtVersion任务的工作方式是不同的。在SBT项目中，sbtVersion显示项目及其子项目使用的SBT版本。

$ 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] exercises/*:sbtVersion
[info]  0.13.1-RC5
[info] scalania/*:sbtVersion
[info]  0.13.1-RC5

在project/build.properties中设置:

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

在SBT项目外部执行的相同任务将显示可执行文件本身的当前版本。

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] Done updating.
[info] Set current project to jacek (in build file:/Users/jacek/)
[info] 0.13.0

当您在外部时，about命令似乎更适合，因为它显示了sbt版本以及Scala的和可用的插件。

jacek:~
$ sbt about

[info] Set current project to jacek (in build file:/Users/jacek/)

你可能想运行'help about'来阅读它的文档:

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.

对于sbtVersion设置，inspect命令可以提供帮助。

$ 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] Delegates:
[info]  *:sbtVersion
[info]  {.}/*:sbtVersion
[info]  */*:sbtVersion
[info] Related:
[info]  */*:sbtVersion

人们似乎希望通过检查了解SBT版本的版本设置是设置当前模块的版本/修订号。

$ 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

在SBT项目中使用时，任务/设置可能会显示不同的输出。
