如何在SBT项目中列出活动插件？

如何查看项目中加载的SBT插件？tasks -V显示discoveredSbtPlugins任务存在,但是

> discoveredSbtPlugins
[success] Total time: 0 s, completed Dec 4, 2015 2:40:02 PM
> show discoveredSbtPlugins
[info] Compiling 1 Scala source to /home/aromanov/IdeaProjects/splinter/splinter-core/target/scala-2.11/classes...
[info] splinter-core/compile:discoveredSbtPlugins
[info]  sbt.PluginDiscovery$DiscoveredNames@37eda1fc
[info] splinter/compile:discoveredSbtPlugins
[info]  sbt.PluginDiscovery$DiscoveredNames@5225c413

不是特别有用.

尝试plugins在sbt控制台中输入内容.

> plugins
In file:/Users/martin/Desktop/sbt-memory/
sbt.plugins.IvyPlugin: enabled in sbt-memory
sbt.plugins.JvmPlugin: enabled in sbt-memory
sbt.plugins.CorePlugin: enabled in sbt-memory
sbt.plugins.JUnitXmlReportPlugin: enabled in sbt-memory
