合併策略不適用於sbt-assembly的重複數據刪除問題

Question

嘗試運行assembly時出現重複數據刪除錯誤。我已經使用了一些對我的合併策略不同的方法來嘗試解決這一問題，但沒有人似乎工作..

SBT輸出錯誤

正如你可以看到我已經嘗試了幾個不同的東西，但他們都沒有看到匹配的情況。我可以得到一些幫助嗎？

Answer 1

我在我的項目的根目錄中使用了assembly.sbt文件，但在build.scala中指定了合併策略設置。一旦我將設置移動到這個文件，一切正常。

Answer 2

試試這個

case x if x.endsWith("spring.tooling") => MergeStrategy.last 

對於我建立的文件看起來不錯，但你可以嘗試添加「的println」語句，看看實際的自定義合併策略時，也許SBT組裝沒有看到它
