23# Gradle start up script for POSIX generated by Gradle.
24#
25# Important for running:
26#
27# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
28# noncompliant, but you have some other compliant shell such as ksh or
29# bash, then to run this script, type that shell name before the whole
30# command line, like:
31#
32# ksh Gradle
33#
34# Busybox and similar reduced shells will NOT work, because this script
35# requires all of these POSIX shell features:
36# * functions;
37# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
38# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
39# * compound commands having a testable exit status, especially «case»;
40# * various built-in commands including «command», «set», and «ulimit».
41#
42# Important for patching:
43#
44# (2) This script targets any POSIX shell, so it avoids extensions provided
45# by Bash, Ksh, etc; in particular arrays are avoided.
46#
47# The "traditional" practice of packing multiple parameters into a
48# space-separated string is a well documented source of bugs and security
49# problems, so this is (mostly) avoided, by progressively accumulating
50# options in "$@", and eventually passing that to Java.
51#
52# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
53# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
54# see the in-line comments for details.
55#
56# There are tweaks for specific operating systems such as AIX, CygWin,
57# Darwin, MinGW, and NonStop.
58#
59# (3) This script is generated from the Groovy template
60# https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
61# within the Gradle project.
