sbt-proguard您必须为收缩步骤指定'-keep‘选项

Question

我正在努力让sbt-proguard插件正常工作。我有一个我想要混淆的类库，但我似乎无法在没有上述错误的情况下让插件输出。我已经指定了keep选项，或者至少我认为我已经指定了，但我没有运气。我从Proguard网站上复制了keep选项，上面说它是为类库准备的。此外，我认为插件不会响应我配置的选项。

例如，我想要有更详细的输出，看看输出是否能给我一个线索，告诉我我做错了什么。但是，每当我查看日志文件时，它总是指定默认选项。下面是我的配置。有人能帮我解决这个问题吗？我完全迷路了。谢谢

我最终通过以下配置让插件完成了我想要做的事情。

  Dependencies.Libraries.commonsCodec,
  Dependencies.Libraries.typeSafeConfig
)

ProguardKeys.proguardVersion in Proguard := "5.2.1"

ProguardKeys.options in Proguard ++= Seq("-dontnote", "-dontwarn", "-ignorewarnings")

ProguardKeys.inputs in Proguard <<= (dependencyClasspath in Compile) map { _.files }
