如何在 sbt publish-local 之后引用 jar 文件

Question

spark jar 已成功发布到本地存储库：

sbt publish-local

这是 spark-core 的摘录 - 看起来很健康：

[info] 将 spark-core_2.10 发布到 C:\Users\s80035683.m2\repository\org\apache\spark\spark-core_2.10\1.1.0-SNAPSHOT\spark-core_2.10-1.1.0-SNAPSHOT-javadoc.jar [信息] 发布 spark-core_2.10 到 C:\Users\s80035683.ivy2\local\org.apache.spark\spark-core_2.10\1.1.0-SNAPSHOT\poms\spark-core_2.10.pom [信息] 发布 spark-core_2.10 到 C:\Users\s80035683.ivy2\local\org.apache.spark\spark-core_2.10\1.1.0-SNAPSHOT\jars\spark-core_2.10.jar [信息] 发布 spark-core_2.10 到 C:\Users\s80035683.ivy2\local\org.apache.spark\spark-core_2.10\1.1.0-SNAPSHOT\srcs\spark-core_2.10-sources.jar [信息] 发布 spark-core_2.10 到 C:\Users\s80035683.ivy2\local\org.apache.spark\spark-core_2.10\1.1.0-SNAPSHOT\docs\spark-core_2.10-javadoc.jar [信息] 常春藤发布到 C:\Users\s80035683.ivy2\local\org.apache.spark\spark-core_2.10\1.1.0-SNAPSHOT\ivys\ivy.xml

特别是：这是 .m2 中的一个文件：

C:\Users\s80035683\.m2\repository\org\apache\spark\spark-core_2.10\1.1.0-SNAPSHOT>dir

 Directory of C:\Users\s80035683\.m2\repository\org\apache\spark\spark-core_2.10\1.1.0-SNAPSHOT

尝试使用客户端项目中的 jar 时出现问题。

这是来自客户端 build.sbt 的摘录：

val sparkVersion = "1.1.0-SNAPSHOT"
..
libraryDependencies ++= Seq(
  "org.apache.spark" % "spark-core_2.10" % sparkVersion  % "compile->default"  withSources(),
  "org.apache.spark" % "spark-sql_2.10" % sparkVersion  % "compile->default"  withSources()

..

resolvers  ++= Seq(
  "Apache repo" at "https://repository.apache.org/content/repositories/releases",
  "Local Repo" at Path.userHome.asFile.toURI.toURL + "/.m2/repository",
  Resolver.mavenLocal
)

所以：我们有：

• 一个不错的本地回购
• 一个引用本地 repo 的 build.sbt

但是当我们这样做时：

sbt package

我们对刚刚发布的相同 spark 工件有未解决的依赖关系：

更新根据@lpiepiora 的回答，似乎删除 compile-> 默认值确实（令人惊讶地）有所作为。这是迄今为止的证据。

（使用依赖图插件）：

完成更新。 [信息] 默认值：hspark_2.10:0.1.0-SNAPSHOT [S] [信息]
+-org.apache.spark:spark-core_2.10:1.1.0-SNAPSHOT [S]

Answer 1

尝试为您的依赖项删除映射compile->default。正如文档所说，无论如何它都是多余的：

没有映射（没有“->”）的配置被映射到“默认”或 “编译”。 -> 仅在映射到不同的 配置比那些。

因此声明你的依赖如下：

libraryDependencies ++= Seq(
  "org.apache.spark" % "spark-core_2.10" % sparkVersion withSources(),
  "org.apache.spark" % "spark-sql_2.10" % sparkVersion  withSources()
)

他们应该解决。
