为什么IDEA会因多项目构建失败？

Question

我刚刚添加了一个子项目到我的SBT编译来编译宏。下面是我添加了project/Build.scala：

import sbt._ 

object DevaBuild extends Build { 
    lazy val deva = Project("deva", file(".")) dependsOn macros 
    lazy val macros = Project("macros", file("macros")) 
} 

它建立在命令行罚款，但IntelliJ IDEA的给了我这个错误：

Error:scala: Output path .../deva/project/target/idea-classes is shared between: Module 'deva-build' production, Module 'main-build' production 
Output path .../deva/project/target/idea-test-classes is shared between: Module 'deva-build' tests, Module 'main-build' tests 
Please configure separate output paths to proceed with the compilation. 
TIP: you can use Project Artifacts to combine compiled classes if needed.

您需要更改内部输出pathes项目结构/模块/ “module_name”/唯一值的路径。这是一个分析sbt-idea插件的bug的项目结构，也可能是intellij-sbt插件。
