Question

我有以下Build项目定义，用于设置多项目构建：

import sbt._
import Keys._

object Build extends Build {
  lazy val gostats = ProjectRef(id = "gostats", base = file("modules/gostats_0.1"))

  lazy val godeploy = Project(id = "godeploy", base = file("."))
    .aggregate(gostats).dependsOn(gostats)
}

这编译得很好，但我无法在SBT控制台中运行project gostats。

如果我将ProjectRef更改为Project gostats，则gostats不再编译，因为在这种情况下SBT会忽略我的项目设置。

我怎样才能充分利用两个世界？

如果您使用SBT 0.13.x，则可以在build.sbt中定义Multi-Project Builds。这是在您的对象godeploy之后定义gostats和Build的方法。

lazy val godeploy = project in file(".") aggregate gostats dependsOn gostats

lazy val gostats = project in file("modules") / "gostats_0.1"

有了这个，我可以project没有错误的项目。

[godeploy]> projects
[info] In file:/Users/jacek/sandbox/so/multi-0.13.1-project-ref/
[info]   * godeploy
[info]     gostats
[godeploy]> project gostats
[info] Set current project to gostats (in build file:/Users/jacek/sandbox/so/multi-0.13.1-project-ref/)
[gostats]> projects

SBT还为我创建了项目目录结构，因为我只从build.sbt和project/build.properties文件开始。

jacek:~/sandbox/so/multi-0.13.1-project-ref
$ tree -L 2
.
├── build.sbt
├── modules
│   └── gostats_0.1
└── project
    └── build.properties

3 directories, 2 files

在SBT中使用ProjectRef进行多项目构建时，不能“投射gostats”吗？
