SBT project for java executable jar
提问by Synesso
What is the best way to set the target package for an SBT project to be an executable jar file?
将 SBT 项目的目标包设置为可执行 jar 文件的最佳方法是什么？
It would need to bundle scala-library.jar and set the manifest for main-method.
它需要捆绑 scala-library.jar 并设置 main-method 的清单。

Use the assembly-sbt plugin (originally created by Coda Hale, now maintained by Eugene Yokota): https://github.com/sbt/sbt-assembly
使用 assembly-sbt 插件（最初由 Coda Hale 创建，现在由Eugene Yokota维护）：https: //github.com/sbt/sbt-assembly
Once you add this to your project it will build a so-called "fatjar" which is executable via java -jar projectName-assembly.jar. It will autodetect your main method -- if there is more than one in your source, you can explicitly set which one to use by setting mainclass, e.g.:
一旦你将它添加到你的项目中，它就会构建一个所谓的“fatjar”，它可以通过java -jar projectName-assembly.jar. 它将自动检测您的主要方法——如果您的源中有多个方法，您可以通过 setting 明确设置要使用的方法mainclass，例如：
mainClass in assembly := Some("com.package.ClassNameWithMain")
