android-sdk-plugin 项目不知道 Android 类

Question

我有 Ubuntu 15.04 64 位、Scala 2.11.6 和 sbt 0.13.8。我安装了 android-sdk，至少 android-22，并且 ANDROID_HOME 设置正确。

我按照 android-sdk-plugin 中的 "Usage" 部分做了以下操作：

创建了一个包含以下文件的新目录：
- build.sbt:

lazy val root = (project in file (".")).
  settings(
    name := "Test",
    version := "0.0.1",
    scalaVersion := "2.11.6"
)

project/plugins.sbt:

addSbtPlugin("com.hanhuy.sbt" % "android-sdk-plugin" % "1.4.1")

project/build.scala:

object Build extends android.AutoBuild

运行 sbt 并得到以下输出：

Picked up JAVA_TOOL_OPTIONS: -javaagent:/usr/share/java/jayatanaag.jar
[info] Loading global plugins from /home/pcn/.sbt/0.13/plugins

在 sbt 的提示符下，键入 gen-android android-22 com.pcn.android.test Test 并得到以下输出：

在 sbt 的提示符下，键入 compile 并得到以下输出：

正如我们所见，出于某种原因它不知道 Activity 和其他 Android 类。我做错了什么，我该如何解决？我是 sbt 的完全菜鸟，所以如果我能得到详细的说明就太好了。

谢谢。

PS：这是我的~/.sbt/0.13/global.sbt的内容，如果相关的话：

scalacOptions ++= Seq("-deprecation", "-feature", "-optimize")

您在 build.sbt 中所做的事情混淆了 AutoBuild。您可以从 build.sbt 中删除项目定义，或删除 AutoBuild 并手动将 androidBuild 应用于项目。
