在sbt中添加仅编译时依赖项 [英] Add a compile time only dependency in sbt

问题描述

我想向仅用于编译的sbt项目添加依赖项.它既不应在运行时类路径上，也不应在已发布的POM中以任何形式显示.

I would like to add a dependency to an sbt project which is only used for compilation. Neither should it be on the runtime class path, nor should it be visible in any form in the published POM.

想法是添加一个仅存根的库( OrangeExtensions )，以便可以在任何平台上编译该项目，而不仅仅是OS X.

The idea is to add a stub only library (OrangeExtensions) so that the project can be compiled on any platform not just OS X.

是否可能这样:

libraryDependencies += "com.yuvimasory" % "orange-extensions" % "1.3.0" % ???

?

推荐答案

您可以创建自定义

You can create a custom dependency configuration for this (actually, this is getting so common when you use private macros in your project, I wish SBT provided one).

在build.sbt中:

// a 'compileonly' configuation
ivyConfigurations += config("compileonly").hide

// some compileonly dependency
libraryDependencies += "commons-io" % "commons-io" % "2.4" % "compileonly"

// appending everything from 'compileonly' to unmanagedClasspath
unmanagedClasspath in Compile ++= 
  update.value.select(configurationFilter("compileonly"))

该依赖项不会出现在publish和朋友生成的pom.xml中.

That dependency will not appear in the pom.xml generated by publish and friends.

几乎有 个可用的配置:provided配置.除了provided作为provided范围的依赖项最终出现在pom.xml中.另外，provided表示运行时本身在运行时提供此功能"，而不是运行时不需要此功能".

There almost is such a configuration available: the provided configuration. Except that provided ends up in the pom.xml as a dependency with provided scope. Also, provided means "the runtime itself provides this at runtime", not "this is not needed at runtime".
