Prerequisites #

Install JDK 21 or later. Verify:

java -version

Expected output: java version "21.x.x" ...

Run the Application #

java -jar claudius-corp-3.1.0.jar

Launcher Script #

For convenience, use the provided start.bat:

start.bat

In development mode (full Maven source tree), start.bat uses mvn javafx:run. In production (JAR-only), it runs java -jar.

Portable Mode #

If Claudius Corp detects it is running from a removable drive or a non-standard path, it enters portable mode. In portable mode, all data (database, logs, backups) is stored in the application folder rather than %APPDATA%.

Portable mode is detected automatically via PortableMode.java. To force portable mode, place an empty portable.flag file in the application root.
