創建工程
添加插件assembly
插件作用
打fat jar
添加方法
打開project/plugins.sbt添加以下內容
addSbtPlugin(“com.eed3si9n” % “sbt-assembly” % “0.14.1”)
添加依賴
打開工程根目錄下的build.sbt文件添加以下內容
//指定mainClass
mainClass in (Compile, packageBin) := Some(“com.kunyandata.newsparser.OperateHbase.HbaseOperation”)
//jar包名
name := “newspaper”
//工程版本
version := “1.0”
//scala版本
scalaVersion := “2.10.5”
//添加依賴
libraryDependencies += “org.scala-lang” % “scala-compiler” % “2.10.5”
//解決依賴重複的問題
