如何在 SBT 中获取内部项目依赖 jar 路径

问题描述

我正在 SBT 中实现自定义部署任务，我需要将所有必需的 jar 复制到部署文件夹.我能够使用 update TaskKey 获取所有外部依赖项的路径.不幸的是 updateReport 不包含内部依赖项.这是我的简单配置

I am implementing custom deploy Task in SBT and I need to copy all required jars to deployment folder.I am able to get paths to all external dependencies using update TaskKey. Unfortunately updateReport does not include internal dependencies.Here is my simple configuration

val deploy = TaskKey[Unit]("deploy","deploy")

lazy val projectA = Project(id=project-a,
settings=Project.defaultSettings)

lazy val projectB = Project(id=project-b,
settings=Project.defaultSettings) dependsOn(projectA)

lazy val projectC = Project(id=project-c,
settings=Project.defaultSettings, ++ Seq(deployTask)) dependsOn(projectB)

val deployTask = deploy <<= (update) map {(updateReport) =>
val externalDependency = updateReport.allFiles //paths to all external dependencies are available here
//project-a.jar and project-b.jar are not here
}

所以，问题是如何获取内部项目依赖项的绝对路径，即 project-a.jar、project-b.jar

So, the question is how can I obtain absolute path to internal project dependencies i.e. project-a.jar, project-b.jar

推荐答案

如果你设置了 exportJars 属性:

If you set the exportJars property:

exportJars := true

然后

exportedProducts in Compile

应该给你一个项目的 jar 文件的路径:

Should give you the path to the jar file for a project:

> show export-jars
[info] true
> show exported-products
[info] List(Attributed(/Users/luke/Work/myproject/server/target/scala-2.9.2/server_2.9.2-0.3-SNAPSHOT.jar))
