「./sbt/sbt assembly」錯誤「Apache Spark項目的無效命令：assembly」

Question

我在Ubuntu 13.04上安裝Apache Spark時遇到了問題。我使用spark-0.8.1-incubating，並且./sbt/sbt update和./sbt/sbt compile都正常工作。但是，當我做了./sbt/sbt assembly我得到以下錯誤：

[info] Set current project to default-289e76 (in build file:/node-insights/server/lib/spark-0.8.1-incubating/sbt/) 
[error] Not a valid command: assembly 
[error] Not a valid project ID: assembly 
[error] Not a valid configuration: assembly 
[error] Not a valid key: assembly 
[error] assembly 
[error]    

我GOOGLE了與此相關的東西，但找不到任何有用。任何指導將不勝感激。

Answer 1

的current project set to default-289e76消息表明，sbt從星火來源目錄以外的叫：

$ /tmp ./spark-0.8.1-incubating/sbt/sbt assembly 
[info] Loading global plugins from /Users/joshrosen/.dotfiles/.sbt/plugins/project 
[info] Loading global plugins from /Users/joshrosen/.dotfiles/.sbt/plugins 
[info] Set current project to default-d0f036 (in build file:/private/tmp/) 
[error] Not a valid command: assembly 
[error] Not a valid project ID: assembly 
[error] Not a valid configuration: assembly 
[error] Not a valid key: assembly 
[error] assembly 
[error]  ^

運行./sbt/sbt assembly工作從spark-0.8.1-incubating目錄罰款（注意顯示，目前項目已正確設置日誌的輸出）：

$ spark-0.8.1-incubating sbt/sbt assembly 
[info] Loading global plugins from /Users/joshrosen/.dotfiles/.sbt/plugins/project 
[info] Loading global plugins from /Users/joshrosen/.dotfiles/.sbt/plugins 
[info] Loading project definition from /private/tmp/spark-0.8.1-incubating/project/project 
[info] Loading project definition from /private/tmp/spark-0.8.1-incubating/project 
[info] Set current project to root (in build file:/private/tmp/spark-0.8.1-incubating/) 
... 

Answer 2

您鍵入了「abt」兩次，但不應該是「sbt」？ Apache Spark有自己的sbt副本，所以確保你運行的是Spark的版本，以便在其他自定義設置中選取「程序集」插件。

要運行sbt的Spark安裝，請轉到Spark目錄並運行./sbt/sbt assembly。
