斯卡拉简单的虚拟项目

时间：2010-05-11 01:03:45

标签： scala project-management scala-2.8 sbt

目前我的整个工作周期是：

  1. 编辑foo.scala
  2. fsc foo.scala＆amp;＆amp; scala -cp。 FooMain

    3. 但我的项目越来越大，我想分割文件，进行单元测试等。 但是我懒得阅读sbt文档并做任何需要做的事来获得sbt的“Makefile”。类似的单元测试（有很多框架可供选择？）

    什么使我的一天是一个简单的压缩虚拟项目与虚拟单元测试使用sbt。

    你知道这样的事情是否存在吗？

好吧，你应该使用SBT。您不需要为它编写任何内容：它将创建基本项目所需的所有内容，并且只询问您项目名称是什么以及您将使用的Scala版本。

之后，只需将文件放在正确的位置即可。查找目录布局，但简短的答案是src/main/scala中的主要源文件和src/test/scala中的测试源文件。但 必须创建一个非常小的“makefile”来获取测试库。

更新回答（2016）

现在，您拥有Giter8项目，并结合了sbt的启动器版本0.13.13或更高版本，and its command new。

sbt new ...

原始答案（2010）

是的，存在这样一个基于sbt的模板项目，包括scala测试：

请参阅Get Started With Scala, Sbt And Eclipse及其template project。

  • 1）克隆或从sbt-console-template
    • 下载/提取源代码 
    % git clone git://github.com/mgutz/sbt-console-template.git  your-project
  • 2）来自sbt console 
       # update dependencies
       > update

       # run project
       > run

       # test project continuously
       > ~test

       # eclipsify
       > eclipse

（“eclipse”部分是可选的，只有在你想从你的sbt项目中生成Scala eclipse项目时才会在这里）

另一个Scala模板项目：

<强> Build a mixed Scala 2.8/Java application from scratch with Maven

它使用以下模板（此处为zip file with the full Maven-Scala project）：

+-scalajavatut/
  +-pom.xml
  +-src/
  | +-main/
  | | +-java/
  | | | +-de/
  | | |   +-mackaz/
  | | |     +-HelloScala.java
  | | +-scala/
  | |   +-de/
  | |     +-mackaz/
  | |       +-App.scala
  | +-test/
  |   +-scala/
  |     +-de/
  |       +-mackaz/
  |         +-AppTest.scala
  |         +-MySpec.scala

以下pom.xml：

您可以使用以下命令运行它：

mvn scala:run
  

在输出结束时你应该看到

[INFO] launcher 'myLauncher' selected => de.mackaz.App
