Versionpass allows 1.20.30 clients to join a 1.20.40 server

Note: VersionPass requires 2 NBT files downloaded and placed in the data directory from here

(download the block_palette.1_20_30.nbt and block_palette.1_20_40.nbt files)

__ProxyPass requires Java 17 or later
If using VersionPass in offline mode (default), online-mode needs to be set to false in server.properties so that ProxyPass can communicate with your Bedrock Dedicated Server. Credentials in online-mode can be saved by setting save-auth-details to true.

To produce a jar file, run ./gradlew shadowJar in the project root directory. This will produce a jar file in the build/libs directory.

If you wish to run the project from source, run ./gradlew run in the project root directory.
