Question

我正在构建一个SBT多项目项目，该项目包含common模块和logic模块以及logic.dependsOn(common)。

在common中，SparkSQL 2.2.1（＆＃34; org.apache.spark＆＃34; %%＆＃34; spark-sql＆＃34;％＆＃34; 2.2.1＆＃34; ）介绍。在logic中，也使用了SparkSQL，但是我得到了编译错误，说＆＃34;对象spark不是org.apache包的成员＆＃34;。

现在，如果我将logic的SparkSQL依赖项添加为"org.apache.spark" %% "spark-sql" % "2.2.1"，它就可以了。但是，如果我添加"org.apache.spark" %% "spark-sql" % "2.2.1" % Provided"，我会收到同样的错误。

我不知道为什么会发生这种情况，为什么依赖关系无法从common转移到logic

这是root sbt文件：

lazy val commonSettings = Seq(
  organization := "...",
  version := "0.1.0",
  scalaVersion := "2.11.12",
  resolvers ++= Seq(
    clojars,
    maven_local,
    novus,
    twitter,
    spark_packages,
    artima
  ),
  test in assembly := {},

  assemblyMergeStrategy in assembly := {...}
)

lazy val root = (project in file(".")).aggregate(common, logic)

lazy val common = (project in file("common")).settings(commonSettings:_*)

lazy val logic = (project in file("logic")).dependsOn(common).settings(commonSettings:_*)

这是逻辑模块sbt文件：

libraryDependencies ++= Seq(
  spark_sql.exclude("io.netty", "netty"),
  embedded_elasticsearch % "test",
  scalatest % "test"
)

dependencyOverrides ++= Seq(
  "com.fasterxml.jackson.core" % "jackson-core" % "2.6.5",
  "com.fasterxml.jackson.core" % "jackson-databind" % "2.6.5",
  "com.fasterxml.jackson.module" % "jackson-module-scala_2.11" % "2.6.5",
  "com.fasterxml.jackson.core" % "jackson-annotation" % "2.6.5",
  "org.json4s" %% "json4s-jackson" % "3.2.11"
)

assemblyJarName in assembly := "***.jar"

SBT多项目中的传递依赖性错误
