sbt publish-local后如何引用jar文件

Question

sbt publish-local

[info]将spark-core2.10发布到C:\users\s80035683.m2\repository\org\apache\spark-core2.10\1.1.0-Snapshot\spark-core2.10\1.1.0-Snapshot-javadoc.jar[info]将spark-core2.10发布到C:\users\s80035683.ivy2\local\org.apache.spark\poms\spark-core2.10\1.1.0-Snapshot\poms\spark-core2.10.pom[info]将spark-core2.10发布到

特别是：这里有一个.m2：

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

当尝试使用客户端项目中的JAR时，问题就出现了。

以下是客户端build.sbt的节选：

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：

null

sbt package

（使用依赖关系图插件）：

完成更新。[info]默认值:hspark2.10:0.1.0-snapshot[S][info]
+-org.apache.spark:spark-core2.10:1.1.0-snapshot[S]

Answer 1

尝试删除依赖项的映射compile->default。无论如何，它是多余的，正如文档所说：

没有映射的配置（没有“->”）被映射到“default”或“compile”。仅当映射到与这些配置不同的配置时才需要->。

因此,按照以下方式声明依赖项：

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