How to decompile Minecraft using MCP with FML repackaged class names, _without_ FML's other changes (client/server merge with MCPMerger, access changes with AccessTransformer, and source patches)

gistfile1.txt

Install MCP 7.25 for Minecraft 1.4.6 from http://mcp.oceanlabs.de/index.php/MCP_Releases into mcp725-pkgd

Install FML:

git clone https://github.com/cpw/FML
cd FML
ant

Copy FML's MCP configuration to the clean MCP installation (this includes the packaged mappings):

cp mcp/conf/* ../mcp725-pkgd/conf/

Apply FML commands patch to allow 'side 2' (client + server) to be recognized:

cd ../mcp725-pkgd/runtime
patch < ../../FML/commands.patch

Remove the checks to prevent decompiling server standalone: https://gist.github.com/4366195

conf/patches/* will patch fail, causing server recompile to fail: https://gist.github.com/4366211
Fix by applying this patch: https://gist.github.com/4366286
./recompile.sh should then work
./updatemd5.sh
yes

Decompiled source will now be in src/minecraft and src/minecraft_server as usual, but with FML/Forge-style package names instead of net.minecraft.src
