The copied version jar (1.20.1-forge-47.4.20.jar) is now on -cp so
securejarhandler can scan it and create the minecraft module. The jar
name does not match the ignoreList pattern forge- (starts with 1),
so it is included in the module layer. This ensures PreparableReloadListener
and other vanilla classes are findable in the minecraft module.
securejarhandler creates the minecraft module from versions/<versionId>/<versionId>.jar.
The Forge installer only creates the JSON there, not the jar. Without the jar,
securejarhandler cannot create the minecraft module, causing ClassNotFoundException
for PreparableReloadListener (a vanilla MC class expected in the minecraft module).
Fix: copy the vanilla version jar (e.g. versions/1.20.1/1.20.1.jar) to the
Forge version directory (e.g. versions/1.20.1-forge-47.4.20/1.20.1-forge-47.4.20.jar)
before launch. The jar is NOT put on -cp to prevent automatic module _1._20._1
from being created, which would conflict with the minecraft module (split-package).
Also removed patched forge client jar from -cp since securejarhandler excludes it
via -DignoreList (forge-* pattern).
Vanilla 1.20.1.jar on -cp creates automatic module _1._20._1 which
conflicts with Forge minecraft module. Use forge-*-client.jar from
libraries/ instead (contains all MC classes). Falls back to vanilla.
Forge manifest -p is 8 hardcoded bootstrap JARs using ${library_directory},
not ${classpath}. Intercepting it replaced those with ALL libraries causing
duplicate module errors. Version jar stays on -cp only (not -p).
- Build two separate classpaths: modulePath (libraries only) and classpath (libraries + version jar)
- Intercept manifest -p to use modulePath (no version jar) preventing _1._20._1 vs minecraft module conflict
- Intercept manifest -cp to skip (our explicit -cp already added)
- Fix --version to use getVersionId() instead of instance.getName()
Forge version.json uses -p ${classpath} to set the module path to the same
argfile as the classpath. Previously we filtered net.minecraft:* libs from the
classpath string, which meant they were absent from the module path too, causing
ClassNotFoundException for PreparableReloadListener and other MC classes.
Now net.minecraft:* libs are included in the Forge classpath argfile so
securejarhandler can load them as modules.
