在使用sbt-native-packager构builddocker软件包时使用重复映射

我正在使用sbt-native-packager在Scala中构build基于Akka HTTP应用程序的Docker镜像。 但是，最近它已经开始运行sbt docker:publishLocal时抛出以下错误sbt docker:publishLocal命令：

看起来像相对较新的SBTfunction， 在这里input链接描述是造成这个问题。

将此添加到您的版本：

 updateOptions := updateOptions.value.withCachedResolution(false) 

为我解决了它。
