# ViaLegacy
ViaVersion addon to add support for EVERY minecraft server version (Classic, Alpha, Beta, Release, April Fools).
## Supported Server versions
- Classic (c0.0.15 - c0.30 including [CPE](https://wiki.vg/Classic_Protocol_Extension))
- Alpha (a1.0.15 - a1.2.6)
- Beta (b1.0 - b1.8.1)
- Release (1.0.0 - 1.7.10)
- April Fools (3D Shareware, 20w14infinite)
- Combat Snapshots (Combat Test 8c)
## Releases
### Gradle/Maven
To use ViaLegacy with Gradle/Maven you can use this [Maven server](https://maven.lenni0451.net/#/releases/net/raphimc/ViaLegacy) or [Jitpack](https://jitpack.io/#RaphiMC/ViaLegacy).
You can also find instructions how to implement it into your build script there.
### Jar File
If you just want the latest jar file you can download it from this [Jenkins](https://build.lenni0451.net/job/ViaLegacy/).

#
# Gradle start up script for POSIX generated by Gradle.
#
# Important for running:
#
# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
# noncompliant, but you have some other compliant shell such as ksh or
# bash, then to run this script, type that shell name before the whole
# command line, like:
#
# ksh Gradle
#
# Busybox and similar reduced shells will NOT work, because this script
# requires all of these POSIX shell features:
# * functions;
# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
# * compound commands having a testable exit status, especially «case»;
# * various built-in commands including «command», «set», and «ulimit».
#
# Important for patching:
#
# (2) This script targets any POSIX shell, so it avoids extensions provided
# by Bash, Ksh, etc; in particular arrays are avoided.
#
# The "traditional" practice of packing multiple parameters into a
# space-separated string is a well documented source of bugs and security
# problems, so this is (mostly) avoided, by progressively accumulating
# options in "$@", and eventually passing that to Java.
#
# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
# see the in-line comments for details.
#
# There are tweaks for specific operating systems such as AIX, CygWin,
# Darwin, MinGW, and NonStop.
#
# (3) This script is generated from the Groovy template
# https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
# within the Gradle project.
#
# You can find Gradle at https://github.com/gradle/gradle/.
