McAssetExtractor is a tool to extract assets from Minecraft by downloading from Mojang's API. It uses GSON to parse the API's JSON responses.
The wiki.vg page on Game files is a helpful resource to understand how this works.
The primary goal of McAssetExtractor is to provide a convenient way to obtain Minecraft's assets while avoiding copyright issues. By providing a tool to download assets from Mojang, we avoid any potential copyright issues from distributing Minecraft's assets.
Make sure you have Apache Maven installed, then run mvn package
to build. The output JAR will be found in the target/ directory.
McAssetExtractor requires Java 1.8 or higher. Use
java -jar McAssetExtractor-1.0-jar-with-dependencies.jar <version> <destination> to extract
assets, replacing <version> with your desired version, and
<destination> with a path to the destination directory.
You can use the latest release or snapshot by setting the version to
latest or latest-snapshot, respectively.
This should give an output similar to the following:
Downloading assets for version 1.19
Extracting assets from client JAR
...
Downloading assets from launcher meta
...
Summary:
Extracted XXX assets from JAR
Extracted XXX assets from launcher meta
If any errors are present, make sure you are connected to the internet, and that you have specified a valid version and output directory.
