Generate Vanilla Source

Run genSources

./gradlew genSources

Source jars will be generated under following paths:

• ./.gradle/loom-cache/minecraftMaven/net/minecraft/minecraft-common-<hash>/<version>/minecraft-common-<hash>-<version>-sources.jar
• ./.gradle/loom-cache/remapped_mods/<mapping_version>/net/fabricmc/fabric-api/<module>/<version>/<module>-<version>-sources.jar

Inspect JAR contents in memory (no extraction to disk)

# Example: Read LivingEntity.java from minecraft-common sources JAR
$jarPath = ".gradle\loom-cache\minecraftMaven\net\minecraft\minecraft-common-<hash>\<version>\minecraft-common-<hash>-<version>-sources.jar"
Add-Type -AssemblyName System.IO.Compression.FileSystem
$zip = [System.IO.Compression.ZipFile]::OpenRead($jarPath)
$entry = $zip.Entries | Where-Object { $_.FullName -eq "net/minecraft/entity/LivingEntity.java" }
$stream = $entry.Open()
$reader = New-Object System.IO.StreamReader($stream)
$content = $reader.ReadToEnd()
$reader.Close()
$stream.Close()
$zip.Dispose()

# Search for specific methods or patterns
$content | Select-String -Pattern "methodName" -Context 5,10

# Extract specific line ranges
$lines = $content -split "`n"
$startIndex = ($lines | Select-String -Pattern "public void methodName" | Select-Object -First 1).LineNumber - 1
$lines[$startIndex..($startIndex + 20)] -join "`n"
