How to have sbt multi-project builds configure setting for subprojects?

由 廉价感情. 提交于 2019-12-23 01:52:43
问题 I have an sbt (0.13.1) project with a bunch of subprojects. I am generating eclipse project configurations using sbteclipse. My projects only have scala source files, so I want to remove the generated src/java folders. I can achieve that by (redundantly) adding the following to the build.sbt of each subproject: unmanagedSourceDirectories in Compile := (scalaSource in Compile).value :: Nil unmanagedSourceDirectories in Test := (scalaSource in Test).value :: Nil I tried just adding the above

how to cache the results of an sbt TaskKey?

由 六眼飞鱼酱① 提交于 2019-12-22 22:23:51
问题 I have an expensive task that I need to reference in my tests lazy val exampleSources = TaskKey[Seq[File]]("exampleSources", "for use in tests") exampleSources := (updateClassifiers in Test).value.select( artifact = artifactFilter(classifier = "sources") ) (and then I can pass exampleSources.value as a parameter to my forked tests) However, every time I run a test, this task is called, and updateClassifiers (expensive) is called. But I'm happy caching the value on first call and then using

Error while importing SBT project

问题 The below is the Log that i can see when building the SBT project.What is the below trying to say ! I'm using IntelliJ IDE and Scala 2.12 and SBT 1.0.3 to build the project. I have verified the IDE Proxy settings ,its setup and works fine for other Build tools. Is something missing my SBT installation ?? I tried accessing the failing links in the log and they too are throwing up with errors. "C:\Program Files\Java\jdk1.8.0_131\bin\java" -agentlib:jdwp=transport=dt_socket,address=12805,suspend

Scala类型系统——高级类类型(higher-kinded types)

由 喜欢而已 提交于 2019-12-22 20:08:27
【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 高级类类型就是使用其他类型构造成为一个新的类型，因此也称为 类型构造器(type constructors)。它的语法和高阶函数(higher-order functions)相似，高阶函数就是将其它函数作为参数的函数；高级类类型则是将构造类类型作为参数类型。一个高级类类型可以有一个或者多个类型作为参数。在Scala中，你可以使用type关键字声明，如下： type Callback[T] = Function1[T,Unit] 这里定义了一个高级类类型Callback，该类型接收一个类型 T，并构造一个新的类型Function1。类型Callback不是一个完整的类型，直到它实现了参数化。 Function0，Function1，... 表示接收类型个数1,2,3,... ，如Function0[A]，Function1[A,B]... ，一共23个FunctionX。用于定义匿名语法，实现语法糖。 高级类类型可以用于创建复杂类型，如M[N[T,X],Y]，但可以看作更简单的类型，F[X]。 Higher-kinded types 除了上面说的用关键字type定义的类型外，高级类类型最常见的实现是使用占位符代替。即F[_]，在Scala中，占位符 _ 有特别的意义，可以表示任何东西。 User Story

How to make a SBT task depend on a module defined in the same SBT project?

由 ぐ巨炮叔叔 提交于 2019-12-22 18:36:21
问题 I have module A and module B in a multi-module SBT project. I want to write a resource generator task for module B that invokes code from module A. One way to do this is to pull all the code from module A under project/ but that is unfeasible as module A is massive and I would like to keep it where it is (see https://stackoverflow.com/a/47323703/471136). How do I do this in SBT? Secondly, is it possible to get rid of module B altogether i.e. I want the resource generator task for module A

sbt switch dependencies for runtime

问题 I am developing a spark application which is using xgboost4j. https://github.com/dmlc/xgboost/tree/master/jvm-packages This package requires to be compiled to the local architecture due to local C dependencies of the jar. But the cluster has a different architecture than the development laptop. How can I substitute the package when running sbt assembly via one from the cluster? Or would you suggest to solve this via a % "provided" ? 回答1: Use suffix for (provided/compile) libs as like: val

sbt play cross build project setup: uTest runner doesn't seperate client/server projects correctly

由 余生长醉 提交于 2019-12-22 17:35:11
问题 I'm using an build.sbt which has cross compile settings and basically is an adapted version of "Play with scala-js example" and having some trouble getting a clean setup for my tests. Specifically, when running my server tests, my client tests also get executed (which is something that I want to avoid). I followed the instructions from Cannot get uTest to see my tests and added libraryDependencies += "com.lihaoyi" %%% "utest" % "0.3.0" My tests for some reason didn't get executed until I
