Play Framework2.2-在主项目中使用来自子项目的类

Question

我试图在main项目(NanoKBWeb)中使用来自我的子项目(NanoKBWeb)的类。Play项目"NanoKBWeb“具有以下目录结构。

└── NanoKBWeb
    ├── NanoKBIndex
    ├── app
    │   ├── Global.java
    │   ├── controllers
    │   ├── models
    │   └── views
    ├── build.sbt
    ├── conf
    │   ├── application.conf
    │   ├── components.xml
    │   ├── messages
    │   ├── routes
    ├── logs
    │   └── application.log
    ├── project
    │   ├── build.properties
    │   ├── plugins.sbt
    ├── public

NanoKBWeb有以下build.sbt。

name := "NanoKBWeb"

version := "1.0"

libraryDependencies ++= Seq(javaJdbc, javaEbean, 
"org.springframework" % "spring-context" % "4.0.1.RELEASE",
"org.apache.lucene" % "lucene-core" % "3.5.0",
"org.apache.lucene" % "lucene-facet" % "3.5.0",
"org.apache.lucene" % "lucene-queryparser" % "3.5.0",
"org.json" % "json" % "20140107"
)

playJavaSettings

lazy val NanoKBIndex  = project.in( file("NanoKBIndex") )

lazy val NanoKBWeb = project.in(file("."))
    .aggregate(NanoKBIndex)
    .dependsOn(NanoKBIndex)

"NanoKBIndex“具有以下目录结构。

├── data
├── lib
├── build.sbt
├── src
│   ├── br
│   │   └── com
│   │       └── caelum
│   │           └── vraptor
│   │               └── blank
│   └── org
│       └── nanokb
│           ├── api
│           ├── common
│           ├── index
│           ├── integration
│           ├── interpreter
│           ├── object
│           ├── search
│           └── test

NanoKBIndex有以下build.sbt。

name := "NanoKBIndex"

version:= "1.0"

libraryDependencies ++= Seq("org.json" % "json" % "20140107",
                    "edu.stanford.nlp" % "stanford-corenlp" % "3.3.1",
                    "edu.stanford.nlp" % "stanford-parser" % "3.3.1",
                     "br.com.caelum" % "vraptor" % "3.5.3"
)

play项目(NanoKBWeb)使用来自子项目(NanoKBIndex)的许多类。当我为NanoKBWeb运行"play编译“时，它会给出来自NanoKBIndex的所有类的错误。

有人能指点我在这里缺少什么吗？
