sbt - 如何设置 sbt-assembly 以包含具有运行时范围的 jar？

Question

如何设置 sbt-assembly 以包含具有运行时范围的 jar？默认情况下不这样做的理由是什么？

Answer 1

我的测试表明该插件确实包含具有范围的依赖项，runtime如以下示例所示。

项目/plugins.sbt

addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.11.2")

构建.sbt

libraryDependencies += "ch.qos.logback" % "logback-classic" % "1.1.2" % "runtime"

assemblySettings

这是一个示例会话：

Answer 2

现在正在sbt/sbt-assembly#120下讨论这个问题。

sbt-assembly 旨在从Runtime配置中连接完整的类路径。它的编码如下：

fullClasspath in assembly <<= fullClasspath or (fullClasspath in Runtime),

对于 Spark，无论出于何种原因fullClasspath都是有线的，所以这很可能会产生干扰。我认为包含 sbt-assembly 的原因fullClasspath现在是历史性的，所以我可能会摆脱“fullClasspath 或”部分。如问题中所述，当前的解决方法可能是：

fullClasspath in assembly := (fullClasspath in Runtime).value

对于那些学习 sbt 的人来说，上面的 sbt-0.13+ 格式:=对应于旧的 pre-sbt-0.13 格式，:=如下所示：

fullClasspath in assembly <<= (fullClasspath in Runtime)
