[英]maven build error when doing serverless deploy to aws ('dependencies.dependency.version' for com.amazonaws:aws-lambda-java-events:jar is missing)
[英]AWS Java Lambda dependency JAR size management with Maven
我有一個 Lambda 函數,使用 Java-11 啟動大約需要 10 秒。 我做了一些谷歌搜索,發現了一些帖子,這些帖子表明降低包的 JAR 大小可能有助於加快啟動時間(減少加載的冗余庫等......)。
我還在一些帖子中讀到使用下面可能會有所幫助並嘗試添加
<scope>provided</scope>
在與 AWS 相關的依賴項中考慮得很好……AWS Lambda 會存在 AWS 特定的庫嗎? 事實證明並非如此! 嘗試執行該功能時,添加提供的范圍不起作用。
我當前的pom.xml

AWS Kinesis 的使用只是創建 KinesisClient 並使用 PutRecordRequest 和 PutRecordResponse 以及 AWS Secret Manager 來訪問特定的秘密。
我不是很精通 AWS API,據我了解,我已經包含了基於依賴項執行這些任務所需的數量有限的庫。
JAR 文件大小約為 65 MB。 我可以進一步優化依賴負載嗎? 我想降低 JAR 文件會增加 Lambda 函數的啟動時間嗎?
謝謝,
我認為您不小心包含了相同依賴項的三個副本。 您只需要最新的 2.xx 版本的 Kinesis 庫。
您當然不需要 1.xx SDK 和 2.xx SDK。
