When uploading data to Amazon S3 I get a NoClassDefFoundError:

exception in thread "main"
java.lang.NoClassDefFoundError: com/amazonaws/auth/AWSCredentials
at athiniocloudmigration.AthinioCloudMigration.main(AthinioCloudMigration.java:30)
Caused by: java.lang.ClassNotFoundException: com.amazonaws.auth.AWSCredentials

This is my compile statement:

javac -d . -cp ../../lib/aws-java-sdk-1.2.7.jar:../ AthinioCloudMigration.java AmazonCloudMigration.java CommonResources.java

And this is how I run it: 

java -cp ../../lib/*.jar:. athiniocloudmigration.AthinioCloudMigration
