Thanks all
Actually I have a generic shell script that for a given Scala program
creates jar file using Maven or SBT.
I modified that one to create a uber jar file as well using SBT assembly.
The root directory structure in uber has one more sub-directory.
In addition SBT relies on a single sbt file. Maven relies on pom.xml. In
contrast SBT assembly requires a build.sbt file plus assembly,sbt file
The assembly sbt file asssenly.sbt simply has one liner
addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.12.0")
The buid.sbt has the following in my case (a generic one)
lazy val root = (project in file(".")).
settings(
name := "${APPLICATION}",
version := "1.0",
scalaVersion := "2.10.4",
mainClass in Compile := Some("myPackage.${APPLICATION}")
)
libraryDependencies += "org.apache.spark" %% "spark-core" % "1.5.1" %
"provided"
libraryDependencies += "org.apache.spark" %% "spark-sql" % "1.5.1" %
"provided"
libraryDependencies += "org.apache.spark" %% "spark-hive" % "1.5.1" %
"provided"
libraryDependencies += "junit" % "junit" % "4.12"
libraryDependencies += "org.scala-sbt" % "test-interface" % "1.0"
libraryDependencies += "org.apache.spark" %% "spark-streaming" % "1.6.1" %
"provided"
libraryDependencies += "org.apache.spark" %% "spark-streaming-kafka" %
"1.6.1"
// META-INF discarding
mergeStrategy in assembly <<= (mergeStrategy in assembly) { (old) =>
{
case PathList("META-INF", xs @ _*) => MergeStrategy.discard
case x => MergeStrategy.first
}
}
So if I want to create an sbt assembly jar file and assuming that the Scala
file is called TestStream_assembly then I just run the shell script passing
the Application 'A' and type 'T' to the shell
./generic.ksh -A TestStream_assembly -T assembly
For simple sbt that will be
./generic.ksh -A TestStream -T sbt
and for maven it will be
./generic.ksh -A TestStream -T mvn
