s3 event is not triggering AWS Lambda function while uploading jar file from bamboo build plan

s3 event is not triggering AWS Lambda function while uploading jar file from bamboo build plan.

And if I upload Jar manually in s3 Bucket then S3Event is triggering AWS Lambda function correctly. Below are the permission Bucket.

Below is my LambdaFuncton code:

package com.lambda;


import com.amazonaws.services.lambda.AWSLambda;

import com.amazonaws.services.lambda.AWSLambdaClientBuilder;

import com.amazonaws.services.lambda.model.UpdateFunctionCodeRequest;

import com.amazonaws.services.lambda.model.UpdateFunctionCodeResult;

import com.amazonaws.services.lambda.runtime.Context;

import com.amazonaws.services.lambda.runtime.RequestHandler;

import com.amazonaws.services.lambda.runtime.events.S3Event;

import com.amazonaws.services.s3.AmazonS3;

import com.amazonaws.services.s3.AmazonS3ClientBuilder;

import com.amazonaws.services.s3.model.GetObjectRequest;

import com.amazonaws.services.s3.model.S3Object;

import org.apache.commons.io.IOUtils;


import java.io.IOException;

import java.nio.ByteBuffer;


public class TestLambdaS3Event implements RequestHandler<S3Event, String> {


private AmazonS3 s3 = AmazonS3ClientBuilder.standard().build();

AWSLambda s3EventClient = AWSLambdaClientBuilder.standard().build();


public TestLambdaS3Event() {

}



@Override

public String handleRequest(S3Event event, Context context) {

context.getLogger().log("Received event: " + event);


// Get the object from the event and show its content type

String bucket = event.getRecords().get(0).getS3().getBucket().getName();

String key = event.getRecords().get(0).getS3().getObject().getKey();

try {

S3Object response = s3.getObject(new GetObjectRequest(bucket, key));

String contentType = response.getObjectMetadata().getContentType();


byte[] byteArray = IOUtils.toByteArray(response.getObjectContent());

UpdateFunctionCodeRequest request = new UpdateFunctionCodeRequest().withFunctionName("my_function")

.withZipFile(ByteBuffer.wrap(byteArray));

System.out.println("request## " + request);

UpdateFunctionCodeResult responseUpdate = s3EventClient.updateFunctionCode(request);

System.out.println("responseUpdate## "+responseUpdate);

return contentType;

} catch (IOException e) {

e.printStackTrace();

context.getLogger().log(String.format("Error getting object %s from bucket %s. Make sure they exist and"

+ " your bucket is in the same region as this function.", bucket, key));

return e.toString();

}


}


}
