为什么构建火花源会给出“对象sbt不是包com.typesafe的成员”？

Question

我试着用https://github.com/apache/spark插件IntelliJ IDEA编译IntelliJ项目。

我在sbt问题上面临一个错误。因为我不熟悉sbt，所以我不知道如何修复它。

错误消息如下：

[info] Loading project definition from F:\codeReading\sbtt\spark-master\project

Answer 1

星火是由Maven建造的。SBT构建只是一种方便。将其作为Maven项目导入将有更好的结果。

Answer 2

看起来IDEA不喜欢用于sbt阅读器的git项目的项目引用。

当我在克隆项目中运行sbt时，它就出现了：

➜  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/)

在访问定义引用的plugins项目时，可以看到对sbt读取器的git项目的项目引用：

> reload plugins

一个解决方案可能是执行sbt gen-idea来为IDEA生成项目文件。不过这只是猜测而已。
