sbt-buildinfo If you need to share version number between build.sbt and hello.scala, what would you normally do? I don’t know about you, but I would use sbt-buildinfo that I wrote. This can be configured using buildInfoKeys setting to expose arbitrary key values like version or some custom String value. I understand this is not exactly … Read more
now i found the reason, you should define case class in the object and outof the main function. look at here Ok, I finally fixed the issue. 2 things needed to be done: Import implicits: Note that this should be done only after an instance of org.apache.spark.sql.SQLContext is created. It should be written as: val … Read more
From sbt version 0.13.5 you can add to your build.sbt cancelable in Global := true It is defined as “Enables (true) or disables (false) the ability to interrupt task execution with CTRL+C.” in the Keys definition If you are using Scala 2.12.7+ you can also cancel the compilation with CTRL+C. Reference https://github.com/scala/scala/pull/6479 There are some … Read more
Thank you for your interest in Chisel! We generally encourage people to use our chisel-template repo as a starting point for Chisel3 projects: https://github.com/ucb-bar/chisel-template If you want to do the most barebones possible thing. Create this build.sbt and put it in the root directory for your project. scalaVersion := “2.13.8” addCompilerPlugin(“edu.berkeley.cs” % “chisel3-plugin” % “3.5.3” … Read more
Here’s what I have in my SBT (version 0.10) project definition, val Mklauncher = config(“mklauncher”) extend(Compile) val mklauncher = TaskKey[Unit](“mklauncher”) val mklauncherTask = mklauncher <<= (target, fullClasspath in Runtime) map { (target, cp) => def writeFile(file: File, str: String) { val writer = new PrintWriter(file) writer.println(str) writer.close() } val cpString = cp.map(_.data).mkString(“:”) val launchString = … Read more
As for the current version 0.11.2 (2014-03-25), the way to define the merge strategy is different. This is documented here, the relevant part is: NOTE: mergeStrategy in assembly expects a function, you can’t do mergeStrategy in assembly := MergeStrategy.first The new way is (copied from the same source): mergeStrategy in assembly <<= (mergeStrategy in assembly) … Read more
Spark 2.1.0 contains com.fasterxml.jackson.core as transitive dependency. So, we do not need to include then in libraryDependencies. But if you want to add a different com.fasterxml.jackson.core dependencies’ version then you have to override them. Like this: name := “testSpark2” version := “1.0” scalaVersion := “2.11.8” dependencyOverrides += “com.fasterxml.jackson.core” % “jackson-core” % “2.8.7” dependencyOverrides += “com.fasterxml.jackson.core” … Read more
You can do a source dependency on your project like that : lazy val core = RootProject(file(“../CoreLibrary”)) val main = Project(id = “application”, base = file(“.”)).dependsOn(core) I have a working example with a multimodule play build : https://github.com/ahoy-jon/play2MultiModule/blob/master/playapp/project/Build.scala But I think the proper way (it depends of your context) of doing it is to create … Read more
Heiko’s approach will probably work, but will lead to none of the dependencies of the 3rd party lib to be downloaded. If you only want to exclude a specific one use exclude. libraryDependencies += “foo” % “bar” % “0.7.0” exclude(“org.baz”, “bam”) or … excludeAll( ExclusionRule(organization = “org.baz”) ) // does not work with generated poms!
The simplest way of installing SBT on ubuntu is the deb package provided by Typesafe. Run the following shell commands: wget http://apt.typesafe.com/repo-deb-build-0002.deb sudo dpkg -i repo-deb-build-0002.deb sudo apt-get update sudo apt-get install sbt And you’re done !
