我試圖建立一個超級罐子，所以我可以部署我的星火計劃這樣做：星火2 SBT裝配重複數據刪除錯誤斯卡拉2.11.8
運行：
sbt assembly
它輸出了很多錯誤的：
[error] deduplicate: different file contents found in the following:
[error] /Users/samibadawi/.ivy2/cache/commons-collections/commons-collections/jars/commons-collections-3.2.1.jar:org/apache/commons/collections/FastHashMap$CollectionView$CollectionViewIterator.class
[error] /Users/samibadawi/.ivy2/cache/commons-beanutils/commons-beanutils/jars/commons-beanutils-1.7.0.jar:org/apache/commons/collections/FastHashMap$CollectionView$CollectionViewIterator.class
的有關斯卡拉2.10問題的答案沒有工作： spark + sbt-assembly: "deduplicate: different file contents found in the following"
經過多次黑客攻擊之後，我收到了一個hello world項目，沒有使用以下build.sbt文件進行編譯的有用代碼：
這似乎是隨機進入排除和進入合併策略的內容。有沒有更簡單更系統的方法來做到這一點？
（除了使用： 「org.apache.spark」 %% 「火花核」 ％sparkVersion％ 「提供」， 在這種情況下，不存在部署的依賴關係。）
