Question

我有一个build.scala文件，其中的部分看起来像下面的剪辑。我使用sbt-assembly来构建所有依赖库的jar文件以进行部署。

这很好。我的问题是我跑步＆＃39;组装＆＃39;并构建~16MB核心deps文件，然后运行＆＃39; package＆＃39;试图构建core.jar文件。它构建core.jar - 但随后它用空文件覆盖我的core-deps.jar文件（因为core-deps没有自己的代码）。

如何构建core.jar和core-deps.jar并且没有＆＃39; package＆＃39;吹走core-deps.jar？

lazy val deps = Project("core-deps", file("."), 
    settings = basicSettings ++ 
                sbtassembly.Plugin.assemblySettings ++ 
                Seq(assemblyOption in assembly ~= { _.copy(includeScala = false) }) ++
                addArtifact(Artifact("core-deps", "core-deps"), sbtassembly.Plugin.AssemblyKeys.assembly) ++    
                Seq(
                    libraryDependencies ++=
                        // Master list of all used libraries so it gets added to the deps.jar file when you run assembly
                        compile(commons_exec, commons_codec, commons_lang, casbah, googleCLHM, joda_time, scalajack, spray_routing, spray_can, spray_client, spray_caching, akka_actor, akka_cluster, akka_slf4j, prettytime, mongo_java, casbah_gridfs, typesafe_config, logback),
                    jarName in assembly <<= (scalaVersion, version) map { (scalaVersion, version) => "core-deps_" + scalaVersion.dropRight(2) + "-" + version + ".jar" } 
                )) aggregate(core)

lazy val core = project 
    .settings(basicSettings: _*)
    .settings(buildSettings: _*)
    .settings(libraryDependencies ++=
        compile(commons_exec, prettytime, commons_codec, casbah, googleCLHM, scalajack, casbah_gridfs, typesafe_config, spray_routing, spray_client, spray_can, spray_caching, akka_actor, akka_slf4j, akka_cluster, logback) ++
        test(scalatest, parboiled, spray_client)
    )

为什么不使用sbt-assembly附带的assemblyPackageDependency任务？请参阅Excluding Scala library, your project, or deps JARs。

如果由于某种原因你真的想在core-deps项目中禁用package任务，你可以尝试重新布线packageBin：

packageBin := (outputPath in assembly).value

除了返回文件名之外什么都不做。

如何在sbt中从包中排除程序集？
