 First make sure that you have the desired specific version of Minecraft installed. You can do so by creating a new Minecraft profile in the Minecraft launcher, and start the game once. Then, format the biome samplings just as for `minecrack-biome`, and invoke `minecrack-biome-java.jar`:

 The Minecraft version is specified with `-m <version>` and it has to be the same string as shown in the Minecraft launcher (like `1.13.2` or `19w34a`). The `-t <type>` argument specifies the world type (`default`, `flat`, `largeBiomes`, `amplified`, `customized`). The generator options can be set with the argument `-g <string>`, but use this parameter only if you know what you are doing. The Java version will use [Amidst](https://github.com/toolbox4minecraft/amidst) internally to locate your Minecraft installation (`.minecraft`), attach to it and run the tests. If your Minecraft installation is in a non-standard path, pass the argument `--mcpath <path_to_.minecraft>`.
