Question

我使用sbt assembly收到了这些错误。

我正在使用Spark，这似乎是这个问题的根源。

val Spark =  Seq(
  "org.apache.spark" %% "spark-core" % sparkVersion,
  "org.apache.spark" %% "spark-sql" % sparkVersion,
  "org.apache.spark" %% "spark-streaming" % sparkVersion
)

错误：

sbt-assembly: deduplication found error

deduplicating commons-validator - sbt assembly

spark + sbt-assembly: "deduplicate: different file contents found in the following"

Answer 1

这不是问题的答案，但它是一种解决方法。

我希望这可以节省几百个工时。

使用sbt-native-packager代替sbt-assembly。

添加到plugins.sbt：

addSbtPlugin("com.typesafe.sbt" % "sbt-native-packager" % "1.0.0")

在build.sbt

中

enablePlugins(JavaAppPackaging)
enablePlugins(UniversalPlugin)

要为多个Scala版本构建文件，请使用+

+ universal:packageBin

输出将告诉您文件的创建位置。

不幸的是，生成的罐子是压缩的。它不是一个胖罐子。（生成一个胖罐需要sbt-assembly，这有相同的问题）

为了解决这个问题，我制作了一个简单的脚本（在SBT中）解压缩生成的文件并将jar路径写入文件，这样我就可以轻松构建Spark提交脚本。

packageBin in TxtFormat := {

    val zippedJar = "core-backend-1.0.zip"
    val basePath = target.value / "universal"

    // Unzip to folder of JARs
    IO.unzip(basePath / zippedJar, basePath)

    val fileMappings = (mappings in Universal).value
    val sparkScriptOut = basePath / s"${packageName.value}.txt"

    // append all mappings to the list
    fileMappings foreach {
        case (file, name) => IO.append(sparkScriptOut, s"core-backend-1.0/$name${IO.Newline}")
    }
    sparkScriptOut
}

构建zip后，使用它来执行任务：

+ txtFormat:packageBin

Answer 2

assemblyMergeStrategy in assembly := {
case PathList("org", "apache", xs @ _*) => MergeStrategy.last
case PathList("com", "google", xs @ _*) => MergeStrategy.last
case x =>
    val oldStrategy = (assemblyMergeStrategy in assembly).value
    oldStrategy(x)
}

这适合我。

Answer 3

群集应提供Spark依赖项，添加“提供”：

val Spark =  Seq(
    "org.apache.spark" %% "spark-core" % sparkVersion % Provided,
    "org.apache.spark" %% "spark-sql" % sparkVersion % Provided,
    "org.apache.spark" %% "spark-streaming" % sparkVersion % Provided
)

Answer 4

我知道这是一个老问题，但到目前为止给出的解决方案都没有处理我遇到的情况。

似乎有些情况下，没有“提供”的jar依赖于罐子。如果传递依赖关系拉入具有冲突内容的jar，您可以看到同样的错误。在某些情况下，将这些jar作为标记为“提供”的依赖项添加并未解决构建程序集时它们之间的冲突。我发现的唯一解决方案是将它们从程序集中明确地排除，如下所示。

assemblyExcludedJars in assembly := {
    val cp = (fullClasspath in assembly).value
    cp filter { el =>
        (el.data.getName == "unused-1.0.0.jar") ||
        (el.data.getName == "spark-tags_2.11-2.1.0.jar")  
    }
}
