如何查看sbt版本？

Question

如何查看我正在运行的sbt版本？

我有使用的bash文件设置sbt-launch.jar,但它可以工作,但是

$ sbt version

只显示"项目版本"(0.1)和

$ sbt --version

什么也没做.

Answer 1

$ sbt sbtVersion

这将打印当前项目中使用的sbt版本,或者它是每个模块的多模块项目.

$ 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

您可能也想使用sbt about它(复制Mark Harrah的评论):

最近添加了about命令,试图简洁地打印最相关的信息,包括sbt版本.

Answer 2

运行该命令,"sbt sbt-version"将只输出您当前的目录和版本号.

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

Answer 3

sbt about 然后输入以获得SBT版本

Answer 4

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)

这项sbtVersion任务在SBT项目内外的工作方式有所不同.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] 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

它设置为project/build.properties:

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

在SBT项目外执行的相同任务显示了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] 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

当你在外面时,这个about命令看起来更合适,因为它显示了sbt版本以及Scala和可用的插件.

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

您可能希望运行"help about"来阅读其文档:

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.

对于该sbtVersion设置,该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]  (sbt.Defaults) Defaults.scala:67
[info] Delegates:
[info]  *:sbtVersion
[info]  {.}/*:sbtVersion
[info]  */*:sbtVersion
[info] Related:
[info]  */*:sbtVersion

在version人们似乎期望检查知道SBT版本设置来设置当前模块的版本/修订.

$ 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.

Answer 5

您可以使用 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 6

SBT 的最新版本终于支持标准--version标志了！

$ sbt --version

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

（使用 1.6+ 进行测试，但似乎它至少从 1.3.3 就已经存在）
