21# Gradle start up script for POSIX generated by Gradle.
22#
23# Important for running:
24#
25# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
26# noncompliant, but you have some other compliant shell such as ksh or
27# bash, then to run this script, type that shell name before the whole
28# command line, like:
29#
30# ksh Gradle
31#
32# Busybox and similar reduced shells will NOT work, because this script
33# requires all of these POSIX shell features:
34# * functions;
35# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
36# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
37# * compound commands having a testable exit status, especially «case»;
38# * various built-in commands including «command», «set», and «ulimit».
39#
40# Important for patching:
41#
42# (2) This script targets any POSIX shell, so it avoids extensions provided
43# by Bash, Ksh, etc; in particular arrays are avoided.
44#
45# The "traditional" practice of packing multiple parameters into a
46# space-separated string is a well documented source of bugs and security
47# problems, so this is (mostly) avoided, by progressively accumulating
48# options in "$@", and eventually passing that to Java.
49#
50# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
51# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
52# see the in-line comments for details.
53#
54# There are tweaks for specific operating systems such as AIX, CygWin,
55# Darwin, MinGW, and NonStop.
56#
57# (3) This script is generated from the Groovy template
58# https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
59# within the Gradle project.
