Preparation

• Install Java 17 or higher
• Install Maven
• Install Git
• Install IntelliJ (Community Version is fine)
• git clone the OAG repository:
  • create a new folder for OAG:

  mkdir oag

  • jump into the folder:

  cd oag

  • clone the repository:

  git clone https://github.com/The-OAG-Development-Project/Application-Gateway.git

Import project

• Start IntelliJ.
• Open project: ../oag/Application-Gateway/oag
  • This should trigger maven and download dependencies
• Build of the whole project (select Build -> Build Project in the menu).
  • You will have to select a project JDK (IntelliJ prompts for this in the upper right corner.). OAG requires a SDK/JDK >= 17 and runs on Java 17 or higher.

Run project

• Verify tests are green: Right click on the top level of the project ("oag" in the Project window) and select "Run All Tests"
• Run the gateway:
  • Open class OWASPApplicationGatewayApplication
  • Click the green triangle (Line 7) to run OWASPApplicationGatewayApplication.main().
    • note that you need 3 client secrets (i.e. registered OAG as an application in Google, GitHub and oAuth0) to be fully functional with the default sample configuration.
    • For GitHub, this means you will have to register an oAuth App in GitHub. Not that the app needs to reflect your local OAG that runs in IntelliJ.
    • If you do not have these 3 client secrets you will see the following in the logs:

WARN  - Environment variable 'GOOGLE_CLIENT_SECRET' does not exist
WARN  - Environment variable 'GITHUB_CLIENT_SECRET' does not exist
WARN  - Environment variable 'AUTH0_CLIENT_SECRET' does not exist

• these 3 clientID's can be set as environment variables in the operating system or directly in IntelliJ as follows:
  • Menu: Run -> Edit Configuration
  • "+" (Add new Configuration) -> Application (or edit the existing entry)
  • select "org.owasp.oag.OWASPApplicationGatewayApplication" as Main Class
  • in the text field for "environment variables:" add the 3 Secrets: " GOOGLE_CLIENT_SECRET=xxxxx;GITHUB_CLIENT_SECRET=xxxxxx;AUTH0_CLIENT_SECRET=xxxxxx"

• Point your browser to: https://localhost:8080/echo/ -> Note "X-Oag-Status: anonymous" in the returned page
  • Click on "Login with Github"
  • Enter your GitHub credentials
  • If all works fine you will end up on localhost:8080 which displays "httpbin.org"
• Point your browser again to: https://localhost:8080/echo/ -> Note "X-Oag-Status: authenticated" in the returned page

Now you are ready to develop new features in OAG. With this you are ready to develop.
