Question

这是我的Build.scala文件。我正在尝试将一些com.google.api-ads库依赖项导入到我的项目中，并且我一直收到错误，指出“未解析的依赖项路径”。我可以看到这些库在maven回购中存在。

我尝试了各种版本，并尝试导入google-http-client依赖项，这是ads-lib和dfp-axis库的传递依赖项。

object Build extends Build {
    val commonSettings = Seq(
    version := "1.0.0",
    organization := "com.collective",
    scalaVersion := "2.11.2",
    scalacOptions ++= List(
        "-encoding", "UTF-8",
        "-target:jvm-1.7",
        "-feature",
        "-unchecked",
        "-deprecation",
        "-Xlint",
        "-Xfatal-warnings"
   )
   )

   val akkaV = "2.3.6"
   val sprayV = "1.3.2"
   val adsLibVersion = "1.30.0"

   lazy val segmentFetcher = Project("segment-fetcher", file("."))
   .settings(commonSettings: _*)
   .settings(
   name := "Segment Fetcher",
   libraryDependencies ++= Seq(
       "com.typesafe.akka"       %%  "akka-actor"           % akkaV,
       "com.typesafe.akka"       %%  "akka-testkit"         % akkaV     % "test",
       "org.specs2"              %%  "specs2-core"          % "2.3.11"  % "test",
       "io.spray"                %%  "spray-can"            % sprayV,
       "io.spray"                %%  "spray-client"         % sprayV,
       "io.spray"                %%  "spray-httpx"          % sprayV,
       "io.spray"                %%  "spray-routing"        % sprayV,
       "io.spray"                %%  "spray-testkit"        % sprayV    % "test"
       "com.google.api-ads"      %%  "ads-lib"              % adsLibVersion,
       "com.google.api-ads"      %%  "ads-lib-axis"         % adsLibVersion,
       "com.google.api-ads"      %%  "dfp-axis"             % adsLibVersion

   )
   )
}

当我运行sbt compile时，我得到com.google.api-ads依赖项的未解决的依赖项错误

Answer 1

%%是一个特殊的SBT运算符，它将Scala版本后缀为要从MAVEN获取的工件。尝试将%%替换为%以获取Java MAVEN依赖项（Google最有可能的依赖项）。

您可能会注意到SBT尝试获取工件

com.google.api-ads#ads-lib_2.11;1.30.0

但应取而代之的是（不带后缀2.11）

com.google.api-ads#ads-lib;1.30.0

与SBT的Google Ads API依赖关系
