【问题描述】：

我正在使用 sbt-native-packager 在 Scala 中构建我们基于 Akka HTTP 的应用程序的 docker 映像。但是，最近它在运行sbt docker:publishLocal 命令时开始抛出以下错误：

【问题讨论】：

我会尝试删除 Ivy 缓存。

我们知道这个问题。不幸的是，我们不确定这是什么原因。见github.com/sbt/sbt-native-packager/issues/657

实际上，删除 Ivy 缓存似乎奏效了。谢谢，鲁斯兰！

【参考方案1】：

似乎是相对较新的 SBT 功能，this 导致了问题。

将此添加到您的构建中：

updateOptions := updateOptions.value.withCachedResolution(false)

帮我解决了。

【讨论】：

显然，他们已经将该功能作为“实验性”进行了大约 6 年。对于多模块项目来说仍然是一个问题。 github.com/sbt/sbt/issues/413
