Question

我发现有必要将我已经使用一段时间的代码重新组织到一个sbt多项目中。我已经参考了两个来源作为示例：

一个sbt 1. *示例（用作基础），由Pol Bassiner：sbt 1.* multiproject example
Aaron Pritzlaff的sbt <1. *示例（主要用于/ project中的.scala文件）：sbt < 1.* multiproject example

基于以上两个内容，是我项目的当前结构：

    [vgorcinschi@localhost Learning Concurrent Programming Test]$ tree -L 2
.
├── build.sbt
├── chapter01_introduction
│   ├── build.sbt
│   └── src
├── chapter02_concurrency_on_jvm
│   ├── build.sbt
│   └── src
├── chapter03_traditional_concurrency
│   ├── build.sbt
│   └── src
└── project
    ├── build.properties
    ├── Common.scala
    ├── Dependencies.scala
    └── target

8 directories, 7 files

我会按照您的建议急于发布其余配置文件的详细信息，但目前与错误最相关的似乎是根build.sbt。这是它的内容：

name := "learning concurrent programming in scala"
organization in ThisBuild := "ca.vgorcinschi"
scalaVersion in ThisBuild := "2.12.6"

import Dependencies._
import Common

version := "0.0.1"

resolvers += "scalaz-bintray" at "http://dl.bintray.com/scalaz/releases"

lazy val chapter01_introduction = project.
    settings(Common.settings: _*).
    settings(libraryDependencies ++= Dependencies.akkaDependencies)

lazy val chapter02_concurrency_on_jvm = project.
    dependsOn(chapter01_introduction).
    settings(Common.settings: _*, 
    mainClass in Compile := Some("org.learningconcurrency.concurrency_on_jvm.PriorityTaskPool_Ex8")).
    settings(libraryDependencies ++= Dependencies.commonDependencies)

lazy val chapter03_traditional_concurrency = project.
    dependsOn(chapter01_introduction).
    settings(Common.settings: _*).
    settings(libraryDependencies ++= Dependencies.commonDependencies)

lazy val root = (project in file(".")).
    aggregate(chapter01_introduction, chapter02_concurrency_on_jvm, chapter03_traditional_concurrency)

当我将其导入Intellij IDEA（2017.3，同时具有Scala和SBT插件）时，出现此错误：build.sbt]:8: '.' expected but ';' found.

出于兴趣的考虑，这是整个堆栈跟踪：

Error while importing sbt project:

我很乐意告诉您有关问题是在intellij还是sbt方面，我们将提供任何帮助或建议。

Answer 1

我发现了问题所在（很好的问题 s ）：

尽管显示错误消息，但真正的罪魁祸首是以上两行的import Common。删除它可以解决该错误。
然后我又抱怨在子项目中用于追加到通用设置的语法：

设置（通用设置：_ *，编译中的mainClass：= Some（“ org.learningconcurrency.concurrency_on_jvm.PriorityTaskPool_Ex8”））

我将不得不弄清楚如何正确地做它。到目前为止，将其删除有助于我无误地导入项目。

最后，这是对我有用的工作根目录build.sbt：

name := "learning concurrent programming in scala"
organization in ThisBuild := "ca.vgorcinschi"
scalaVersion in ThisBuild := "2.12.6"

version := "0.0.1"

resolvers += "scalaz-bintray" at "http://dl.bintray.com/scalaz/releases"

lazy val chapter01_introduction = project.
    settings(Common.settings: _*).
    settings(libraryDependencies ++= Dependencies.akkaDependencies)

lazy val chapter02_concurrency_on_jvm = project.
    dependsOn(chapter01_introduction).
    settings(Common.settings: _*).
    settings(libraryDependencies ++= Dependencies.commonDependencies)

lazy val chapter03_traditional_concurrency = project.
    dependsOn(chapter01_introduction).
    settings(Common.settings: _*).
    settings(libraryDependencies ++= Dependencies.commonDependencies)

lazy val root = (project in file(".")).
    aggregate(chapter01_introduction, chapter02_concurrency_on_jvm, chapter03_traditional_concurrency)

将sbt多项目导入intellij时出错
