创建简单项目 SBT 0.10.X [英] Create Simple Project SBT 0.10.X

问题描述

(这是对 sbt 未正确创建项目的跟进.该问题未得到解答.)<小时>

基本上，那个问题说我不知道如何在新的 sbt 下创建项目.随着旧的，我只是在一个新文件夹中运行 sbt 并且有一个向导引导我完成设置."

接受的答案没有解释如何创建新的项目，它只是指向文档，它也没有明确说明如何创建一个新项目——只知道如何编写一个 build.sbt 文件.

所以我尝试先写一个 build.sbt 然后在带有 build.sbt 文件的目录中运行 sbt，但我仍然看不到要使用的 src 目录.

有人可以发布一个简单的分步指南(我假设最多有 3 个步骤)指导如何在 sbt 0.10.X 下创建一个新项目?

解决方案

我在这个网页上找到了我一直在寻找的答案:Scala 2.9.1、sbt 0.10 和 ScalaTest 一步一步.>

高级步骤是:

1. mkdir my_project 为你的项目创建一个文件夹

2. 创建一个简单的my_project/build.sbt文件，例如:

   name := "一个项目"版本:=0.1"斯卡拉版本:=2.9.1"libraryDependencies ++= Seq("org.scalatest" %% "scalatest" % "1.6.1" % "test")

3. 创建一个文件 my_project/src/main/scala/HelloWorld.scala，您可以在其中随时创建所需的所有目录(例如创建目录结构 src/main/scala/)

   object Main 扩展 App {Console.println("你好世界！")}

4. 执行你的 sbt 命令:例如sbt 运行

(This is a follow up to sbt not creating projects correctly. The question wasn't answered.)

---

Basically, that question says "I don't know how to create a project under the new sbt. With the old one, I just ran sbt in a new folder and there was a guided wizard that led me through the setup."

The accepted answer does not explain how to create a new project, it just points to the documentation, which also doesn't explicitly say how to create a new project -- only how to write a build.sbt file.

So I tried first writing a build.sbt and then running sbt in the directory with the build.sbt file, but I still don't see a src directory to work with.

Could someone post a simple step-by-step (I'm assuming there are like 3 steps at most) guiding how to create a new project under sbt 0.10.X?

解决方案

I found the answer I was looking for at this webpage: Scala 2.9.1, sbt 0.10 and ScalaTest step-by-step.

The high-level steps are:

1. mkdir my_project make a folder for your project

2. Create a simple my_project/build.sbt file, e.g.:

   name := "A Project"
   
   version := "0.1"
   
   scalaVersion := "2.9.1"
   
   libraryDependencies ++= Seq(
     "org.scalatest" %% "scalatest" % "1.6.1" % "test"
   )
   

3. Create a file my_project/src/main/scala/HelloWorld.scala, where you create all the directories you need as you go (e.g. create the directory structure src/main/scala/)

   object Main extends App { Console.println("Hello World!") }

4. Execute your sbt commands: e.g. sbt run
