lambda函數內的S3認證/無法初始化類com.amazonaws.ClientConfiguration

我有一個scala play應用程序，我試圖運行lambda函數。它從s3桶接收一個新對象的通知，然後獲取該對象並對其進行處理。當我運行S3 put測試以及從s3事件獲取桶詳細信息時，它工作正常。但是，當我嘗試根據事件中的信息獲取對象時，它會失敗。lambda函數內的S3認證/無法初始化類com.amazonaws.ClientConfiguration

private val awsCredentialsProvider = new DefaultAWSCredentialsProviderChain() 
private val amazonS3Client = new AmazonS3Client(awsCredentialsProvider) 
private val bucketName = play.Play.application.configuration.getString("aws.s3.BUCKET") 
val s3object = amazonS3Client.getObject(new GetObjectRequest(bucket, objectKey))

這

val amazonS3Client = new AmazonS3Client()

，但我得到下面的錯誤。

我發現那裏的裝配載行

assemblyMergeStrategy in assembly := { 
    case PathList("javax", "servlet", [email protected]_*) => MergeStrategy.first 
    case PathList([email protected]_*) if ps.last endsWith ".html" => MergeStrategy.first 
    case PathList([email protected]_*) if ps.last endsWith ".properties" => MergeStrategy.first 
    case PathList([email protected]_*) if ps.last endsWith ".xml" => MergeStrategy.first 
    case PathList([email protected]_*) if ps.last endsWith ".types" => MergeStrategy.first 
    case PathList([email protected]_*) if ps.last endsWith ".class" => MergeStrategy.first 
    case PathList([email protected]_*) if ps.last endsWith ".json" => MergeStrategy.discard 
    case "application.conf" => MergeStrategy.concat 
    case "Unwanted.Txt" => MergeStrategy.discard 
    case x => (assemblyMergeStrategy in assembly).value(x) 
}

在去除

case PathList([email protected]_*) if ps.last endsWith ".json" => MergeStrategy.discard

的問題解決在built.sbt文件中的錯誤。顯然它丟棄了aws依賴關係導致上述錯誤的一些重要的json配置文件。
