Most users can simply run the tool locally as described below.\n\nYou can download the latest and previous versions of Snowblower directly from its [project page](https://projects.neoforged.net/neoforged/snowblower).\n\n### Basic usage\n\nThe most common use case is to generate a comprehensive repository of all supported versions. The following command processes every version starting from `1.14.4`, which is the first version where official Mojang mappings are available.\n\n```sh\njava -jar Snowblower.jar --output $OUTPUT --branch $BRANCH --start-over-if-required\n```\n\n- `--output $OUTPUT`: Specifies the output directory for the generated repository.\n  - This can be specified either as an absolute path or some path releative to the `jar` file.\n  - `output/$BRANCH` or `output/$VERSION` is recommended to keep your generated repositories organized. (`$VERSION` being a specific Minecraft version)\n- `--branch $BRANCH`: Designates the target branch, which can be `release` or `dev`.\n  - Using `dev` will include snapshots in the generated output.\n- `--start-over-if-required`: Ensures the process starts from scratch if necessary.\n\n**Note**: Generating every version takes a considerable amount of time.\n\n### Excluding unnecessary files\n\nTo prevent repository clutter and large diffs, especially with structures (`.nbt`) and images (`.png`), it is recommended to exclude them. These files frequently change due to internal version values, causing noise in the commit history.\n\n```sh\njava -jar Snowblower.jar --output $OUTPUT --branch $BRANCH --exclude \"**.nbt\" --exclude \"**.png\" --start-over-if-required\n```\n\n### Processing specific versions\n\nIf you need to generate a repository for a limited range of versions, you can use the `--start-ver` and `--target-ver` flags. This will process everything from the specified start version up to and including the target version.\n\n```sh\njava -jar Snowblower.jar --output $OUTPUT --branch $BRANCH --start-ver 1.20.1 --target-ver 1.21 --start-over-if-required\n```\n\n### Exploring more flags\n\nSnowblower has many more flags and options for advanced users. You can see a complete list by running the jar file without any arguments.\n\n```sh\njava -jar Snowblower.jar\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fneoforged%2Fsnowblower","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fneoforged%2Fsnowblower","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fneoforged%2Fsnowblower/lists"}
