Java

Get Started with Java Development on the atPlatform.

Setting Up Your Development Environment

1. Install Java

The first step in getting your developer environment ready, is to install Java 8 or higher on your local machine.

2. Install Maven

Next step is to install maven and add it to your PATH. Maven is a great tool for managing Java projects and will be useful for development atPlatform applications.

3. Clone the Java Client

Fork our at_java repository Create a new directory on your local machine where you want the java client source code to live. Change directory (cd) into this directory and git clone your fork. Git clone: git clone <your_fork_url> so that the source code is on your local machine.

4. Build `at_java/at_client`

Compile at_java/at_client:

Ensure you are in the at_client directory: cd at_java/at_client.
Run mvn install
You should see [INFO] BUILD SUCCESS

Registration CLI

Be sure you’ve fully set up your development environment. Also ensure you’ve built and deployed the project by running mvn install under the at_java/at_client directory.
Our next step is to run the Register.java CLI to register a new atSign will be onboarded and a set of .atKeys will be generated. You can do this by running:

Linux

java -cp "target/client-1.0-SNAPSHOT.jar:target/lib/*" org.atsign.client.cli.Register <email@email.com>

Windows

java -cp "target/client-1.0-SNAPSHOT.jar;target/lib/*" org.atsign.client.cli.Register <email@email.com>

If successful, the output should be similar:

Getting free atsign
Got atsign: @64husky26
Sending one-time-password to :<email@email.com>
Got response: Sent Successfully
Enter OTP received on: <email@email.com>

You will get a OTP (one-time password) in your entered email. Be sure to enter the OTP as received because it is case-sensitive. If successful, output should be similar to as follows:

xxxx
Validating one-time-password
Got response: Verified

IMPORTANT: There will be a newly generated .atKeys file for your new atSign in ~/.atsign/keys. Congratulations, you’ve successfully registered a new atSign in the Java client. Note: The default properties in config.yaml point to the production environment. Your new atSign will be registered to the root that is defined in config.yaml
