Why I get error ClassNotFoundException: com.amazonaws.auth.AWSCredentialsProvider?

Question

I installed the AWS toolkit for java and connected it to my project in buildpath, I tried to upload file to S3.

File fileOfImages = new File("/sdcard/Save Image Tutorial");
AmazonS3 s3client = new AmazonS3Client(new ProfileCredentialsProvider());        
s3client.putObject(new PutObjectRequest("rosh-haayin-images", "images",fileOfImages)); 

but I get following error :

ClassNotFoundException: com.amazonaws.auth.AWSCredentialsProvider

Could someone explain why this exception occurs?

Answer 1

It means you are missing aws-java-sdk-1.10.X.jar in your project build path.

$ jar tvf /home/xxx/aws-java-sdk/1.10.52/lib/aws-java-sdk-1.10.52.jar |grep AWSCredentialsProvider

   806 Thu Feb 11 22:22:34 IST 2016 com/amazonaws/auth/DefaultAWSCredentialsProviderChain.class

verify that your project refers(Java Build Path) to the jar.
