我有一个非常简单的配置：

  //lazy val bananaRdfProject = RootProject( uri("git://github.com:stample/banana-rdf.git#"+bananaGitBranch) )
  // lazy val bananaRdfProject = RootProject( uri("https://github.com/stample/banana-rdf.git#"+bananaGitBranch) )
  // lazy val bananaRdfProject = ProjectRef( uri("https://github.com/stample/banana-rdf.git#"+bananaGitBranch) ,"banana-rdf")
  lazy val bananaRdfProject = RootProject( file("../banana-rdf") )


  lazy val main = play.Project(appName, appVersion, appDependencies).settings(...)
                     .dependsOn( bananaRdfProject )

我尝试将上述 4 个不同的项目声明用于香蕉 RdfProject。

因为我可能会在本地编辑这个香蕉-rdf，所以我希望每次构建我的游戏项目时都重新编译它，这样我就不必发布香蕉-rdf...

但是当我尝试编译使用香蕉-rdf 的主播放项目时，它不会编译香蕉-rdf，而是尝试编译主项目：编译失败，因为类路径中缺少香蕉-rdf 类。

在尝试编译我的主项目之前不应该编译banana-rdf吗？如果不是，那么依赖外部 RootProject 有什么意义？

项目RootProject(file("../banana-rdf"))引用只是引用根项目，而您真正需要的是对banana-rdf子项目的引用（在rdf子目录中）。

可用的子项目在https://github.com/w3c/banana-rdf/blob/master/project/build.scala中定义。有几个：

[main]> projects
[info] In file:/Users/jacek/sandbox/stackoverflow/19832655/
[info]   * main
[info] In https://github.com/w3c/banana-rdf.git
[info]     banana
[info]     banana-jena
[info]     banana-rdf
[info]     banana-rdf-test-suite
[info]     banana-sesame
[info]     examples
[info]     experimental
[info]     ldp
[info]     patch

要引用banana-rdf，您应该使用以下ProjectRef指向构建配置中的正确模块（子项目）。注意ProjectRef以及子项目的名称 - banana-rdf。

lazy val bananaRdfProject =
  ProjectRef(uri("https://github.com/w3c/banana-rdf.git"), "banana-rdf")

有了它，ProjectRef您应该能够解析banana-rdf子项目中定义的任何类型。

聚合项目和dependsOn 之间存在差异。我认为您需要聚合以使所有项目一起构建，dependsOn 仅确保该项目中的类位于类路径上，但如果您最近没有构建它，它当然可能是一个旧工件。查看 sbt 文档了解更多信息：http ://www.scala-sbt.org/0.12.3/docs/Getting-Started/Multi-Project.html
