Agenta

A authserver and skin fix for legacy versions of minecraft.

Compatibility

Requires Java 7. (In theory this can be built for Java 5, but I lack the build tools required for that.) If running this on Java 12 and newer, please add the following JVM argument: --add-exports java.base/sun.net.www.protocol.http=ALL-UNNAMED

1. As a mod: The same Jar will run on forge, bukkit and Risugami's modloader for Minecaft versions Alpha 1.0.4 to Minecraft release 1.7.10 (These are merely the versions I tested)
2. As a JavaAgent: Add the following JVM argument: -javaagent:{path}/agent.jar (replace path with the location of the agent.jar)
3. Inline/static: In this setup, Agenta is essentially taking over the role of Launching minecraft. Add the following JVM argument and change out {mainClass} as needed depending on which minecraft version you are launching: -Dagenta.main.class={mainClass}
4. As a Bukkit plugin (Tested with bukkit for Minecraft Beta 1.2_01)

JVM/Congig settings

Non of these are needed to launch Agenta. The available contexts are
"*" => ALL
"static" => When Agenta is launched as the main class with the expectation of chainloading another class manually.
"config" => Only appears in the config file.

Fixes

• Skin support for pre 1.7.10 versions
• Cape support for pre 1.7.10 versions
• Sound for versions of the game that predate 1.6
• World savings for certain pre-alpha builds (experimental)
• Forge 1.5.2 being unable to fetch it's library files (experimental)

Note

• The same jar will work for almost every version of minecraft that predates Release 1.8
• Any miscellaneous fabric based modloader should be supported.
• NilLoader can load Agenta. (Agenta doesn't meet the criteria of a NilLoader mod)
• Some ancient versions of Forge/modloader may require you to load Agenta as a jar mod.
• LiteLoader inforces compatibility checks and so can never be fully supported
