为什么 IDEA 在多项目构建中失败？

Question

我刚刚在我的 SBT 构建中添加了一个子项目来编译一个宏。这是我添加的project/Build.scala：

import sbt._

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

它从命令行构建得很好，但 IntelliJ IDEA 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.

Answer 1

您需要将 Project Structure/Module/"module_name"/Paths 中的输出路径更改为唯一值。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。
