Question

这就是我们的项目结构

.
├── build.sbt
├── client
│   └── build.sbt
├── project
│   └── Build.scala
└── worker
    └── build.sbt

项目/ Build.scala

object Dependencies {
   val slf4jApi = slf4jGroup % slf4jModule("api") % slf4jVersion
   val elasticSearch = "org.elasticsearch" % "elasticsearch" % "0.90.7"
}

工人/ build.sbt

import Dependencies._

distJvmOptions in Dist := "-Xms256M -Xmx1024M"

outputDirectory in Dist := baseDirectory.value / "target/dist"

libraryDependencies ++= Seq(
  slf4jApi,
  "org.elasticsearch" % "elasticsearch" % "0.90.7"
)

worker项目中的依赖项未得到解决，我收到以下错误：

build.sbt：1：错误：未找到：对象依赖项 import Dependencies._ ^

我认为build.sbt项目中的worker无法查看Dependencies中的Build.scala对象，但我不确定如何克服此问题。有什么想法吗？

Answer 1

以下配置对我来说运作正常，虽然我没有在您的问题中指出问题，但我在此处将其作为参考。

由于client没有兴趣解决这一特定问题，因此请将其删除（尽管它已在build.sbt下面定义 - 没有build.sbt client已定义。）

<强>项目/ Build.scala

import sbt._

object Dependencies {
   val slf4jApi = "org.slf4j" % "slf4j-api" % "1.7.5"
}

<强> build.sbt

lazy val client, worker = project

<强>工人/ build.sbt

import Dependencies._

libraryDependencies += slf4jApi

通过配置，sbt显示：

[project-build]> sbtVersion
[info] worker/*:sbtVersion
[info]  0.13.1
[info] client/*:sbtVersion
[info]  0.13.1
[info] project-build/*:sbtVersion
[info]  0.13.1
[project-build]> projects
[info] In file:/Users/jacek/sandbox/so/project-build/
[info]     client
[info]   * project-build
[info]     worker
[project-build]> show worker/libraryDependencies
[info] List(org.scala-lang:scala-library:2.10.3, org.slf4j:slf4j-api:1.7.5)

这可能是因为您使用旧版本的SBT（前 0.13 ）吗？
