Why does building Spark sources give "object sbt is not a member of package com.typesafe"?

I tried to compile the https://github.com/apache/spark project using IntelliJ IDEA with the sbt plugin on Windows.

I'm facing an error about sbt. Since I'm not familiar with sbt, I don't know how to fix it.

The error messages are as follows:

[info] Loading project definition from F:\codeReading\sbtt\spark-master\project
[info] Compiling 3 Scala sources to F:\codeReading\sbtt\spark-master\project\target\scala-2.10\sbt-0.13\classes...

Spark is built with Maven. The SBT build is only a convenience. You will have far better results importing it as a Maven project.

It looks like IDEA doesn't like project references to git projects that the Spark build definition uses for sbt-pom-reader.

It's showed up when I ran sbt within the cloned project:

➜  spark git:(master) ✗ xsbt
[info] Loading global plugins from /Users/jacek/.sbt/0.13/plugins
[info] Loading project definition from /Users/jacek/oss/spark/project/project
[info] Loading project definition from /Users/jacek/.sbt/0.13/staging/ec3aa8f39111944cc5f2/sbt-pom-reader/project
[warn] Multiple resolvers having different access mechanism configured with same name 'sbt-plugin-releases'. To avoid conflict, Remove duplicate project resolvers (`resolvers`) or rename publishing resolver (`publishTo`).
[info] Loading project definition from /Users/jacek/oss/spark/project
[info] Set current project to spark-parent (in build file:/Users/jacek/oss/spark/)
>

You can see the project reference to the git project of sbt-pom-reader when accessing the plugins project for which the reference is defined:

> reload plugins

[info] Loading project definition from /Users/jacek/oss/spark/project/project

A solution could be executing sbt gen-idea to generate the project files for IDEA. It's just a guess, though.
