使用Maven创建最基本的Scala项目? [英] Creating the most basic Scala project with Maven?

问题描述

我使用Maven 3创建一个新的Scala项目.据我了解，使用Maven创建新项目的方式是:

I use Maven 3 to create a new Scala project. As far as I understand, the way to create a new project with Maven is by:

mvn archetype:generate

也许我错过了一些东西，但是我什至找不到一个提供最简单的Scala项目的选项(例如，lein new app ...收到的Clojure项目).这里有帮助吗?

Maybe I'm missing out something, but I couldn't find even one option that offers the simplest Scala project (like the one received by lein new app ... for Clojure, for example). Any help here?

推荐答案

您应该可以使用mvn archetype:generate.您可以选择例如org.scala-tools.archetypes:scala-archetype-simple.您需要在mvn archetype:generate命令的输出中的原型名称旁边输入数字，因为数字会随时间变化.还有其他选项，例如本文中所述的eu.stratosphere:quickstart-scala >.

You should be able to use mvn archetype:generate. You can choose, e.g., org.scala-tools.archetypes:scala-archetype-simple. You need to put in the number number next to the archetype name in the output of your mvn archetype:generate command because the numbering can change over time. There are also other options like eu.stratosphere:quickstart-scala as documented in this article.

不过，它们可能有些过时了.我个人更喜欢手动编写pom.xml文件.作为参考，这是与Scala 2.11.6和Scalatest 2.2.5一起使用的最小pom文件:

They may be somewhat outdated, though. I personally prefer writing my pom.xml files manually. For reference, here is a minimal pom file for use with Scala 2.11.6 and Scalatest 2.2.5:
