【问题描述】：
我正在尝试使用 sbt 和 jberkel/android-plugin 在 Scala 和 Akka 中设置简单的 Android 项目。我成功地创建了基于getting started tutorial of android-plugin 的简单应用程序。我还设法组装了 ProGuard 配置，使我能够将 Akka 混合到项目中。
现在我想添加 Akka 配置文件，但我无法做到。我在src/main/resources 文件夹中创建了它，并希望它能够正常工作。不幸的是，在 APK 组装过程中，sbt 失败并出现以下错误：
[trace] Stack trace suppressed: run last Akkdroid/android:package-debug for the full output.
[error] (Akkdroid/android:package-debug)
[error] Using keystore: /home/ghik/.android/debug.keystore
[error] Packaging akkdroid-0.1.apk

[error]

从这些消息中，我推断我的 akkdroid.conf 文件首先被复制（由 ProGuard？）到 classes.min.jar，后来 sbt 尝试构建包含来自 classes.min.jar 和 @987654330 的资源的包@ 它最终会看到我的文件两次。
很遗憾，我不知道为什么会发生这种情况以及如何解决它。
如果有帮助，这是我的 sbt 构建文件（主要从 jberkel's template 生成）：
import sbt._

import AndroidKeys._

javacOptions ++= Seq("-source", "1.6", "-target", "1.6")
)

proguardOption in Android :=

keyalias in Android := "change-me",

}
object AndroidBuild extends Build {
javacOptions ++= Seq("-target", "1.6")
lazy val main = Project(
"Akkdroid",
file("."),
settings = General.fullAndroidSettings ++ Seq(

libraryDependencies += "com.typesafe.akka" % "akka-remote_2.10" % "2.1.2"

)
lazy val tests = Project(
"tests",
file("tests"),
settings = General.settings ++
AndroidTest.androidSettings ++
General.proguardSettings ++ Seq(

)

}
如果能得到一些帮助，我将不胜感激。我几乎没有 Android 或 SBT 方面的经验。
