Getting Started
This is an implementation of an Amazon AWS S3 FileSystem
provider using JSR-203 (a.k.a. NIO2) for Java 8.
Amazon Simple Storage Service provides a fully redundant data storage infrastructure for storing and retrieving any amount of data, at any time.
NIO2 is the new file management API, introduced in Java version 7.
This project provides a complete API implementation, for managing files and folders directly in Amazon S3.
Compatibility¶
We aim to support only the latest LTS versions. At the moment this includes:

Quick start¶
Amazon S3 Setup¶

- Open IAM and go to
Add User
- Set
Access Type

Access key ID
andSecret access key
- you will need them later!
Example¶
Create/load a properties file in your project which defines the following properties:
s3fs.bucket.name=/your-bucket-name-for-test
# http://docs.aws.amazon.com/general/latest/gr/rande.html
s3fs.access.key=access-key-for-test
s3fs.secret.key=secret-key-for-test
# check software.amazon.awssdk.regions.Region for quick list
s3fs.region=eu-central-1
s3fs.protocol=https
These properties can also be exported as environment variables. A complete list is available in the Configuration Options
FileSystems.newFileSystem(URI.create("s3:///"),
new HashMap<>(),
Thread.currentThread().getContextClassLoader());
