MCP-Resource-Downloader

An alternative to downloading resource files for older versions of Minecraft for MCP (Minecraft-Coder-Pack).
Downloads directly from Minecraft servers. No middleman, no sketchy website.

CMD

Usage:

Normal: gradlew -p CMD run --args="{insert arguments here}"
Print out all Minecraft versions: gradlew -p CMD run

Arguments:

• --mcp [MCP directory] - The directory of where MCP is (REQUIRED)
• --mcVersion [Minecraft version] - The version of Minecraft to download resources (REQUIRED)
• --jars - If jar files should be downloaded (NOT required)
• --client - If the client jar should be downloaded (REQUIRED if --jars used)
• --server - If the server jar should be downloaded (REQUIRED if --jars used)
• --libraries - If library jars should be downloaded (NOT required)
• --natives - If natives should be downloaded and extracted (NOT required)
• --linux - If Linux natives should be downloaded and extracted (NOT required even if --natives used)
• --windows - If Windows natives should be downloaded and extracted (NOT required even if --natives used)
• --w32 - If Windows 32-bit natives should be downloaded and extracted (NOT required even if --windows used)
• --w64 - If Windows 64-bit natives should be downloaded and extracted (NOT required even if --windows used)
• --osx - If OSX natives should be downloaded and extracted (NOT required even if --natives used)
• --resources - If resources (sound, music) should be downloaded (NOT required)
• --overwrite - If downloaded files should be overwritten should one already exist (NOT required)

Example:

gradlew -p CMD run --args="--mcp mcp62 --mcVersion 1.2.5 --jars --client --libraries --natives --resources --overwrite"

gradlew -p CMD run --args="--mcp mcp811 --mcVersion 1.6.4 --jars --client --libraries --natives --resources --overwrite"

Troubleshooting:

• I keep getting error FileNotFoundException MCP directory "XXXXXX" does not exist!!
  • Make sure when inputting the --mcp argument you're using either a relative location to the CMD folder (if MCP folder is in root directory -where build.gradle is-, use ../<MCP directory>), or an exact location of where the MCP folder is (ex: C:\Users\User\Downloads\<MCP directory>).

GUI

Easier to use, however more limited than CMD.

Usage:

gradlew -p GUI run

Supported versions:

• 1.19.2
• 1.12
• 1.8
• 1.7.10
• 1.6.4
• 1.2.5
• 1.2.3

Known Issues:

• Server jar can't decompile
  • This is due to Mojang hotfixing server jars years later. This is an MCP problem.
• Certain versions aren't working
  • Create a new issue with the specific version (both Minecraft and MCP) you're having troubles with.
• Mac OS (OSX) users may not have natives extracted
  • Create a new issue. I don't have a Mac, so this cannot be tested.

Found an issue? Create a new GitHub issue.

Workarounds:

• 1.8+
  • Starting the client throws error Can't find the resource index file: assets/indexes/1.8.json
    • Another MCP problem. In directory <MCP Dir>/jars/assets/indexes, rename file <version>.json (ex: 1.12) to 1.8.json
• 1.6+
  • MCP can't decompile because it tries copying launcher files
    • Manually run the decompile script with runtime/bin/python/python_mcp runtime/decompile.py --nocopy --client (Windows: runtime\bin\python\python_mcp runtime\decompile.py --nocopy --client) (in MCP directory) after running MCP-RD in client mode.
• Mac OS (OSX) users may not have natives extracted
  • Manually extract jars files
