## Gradle start up script for UN*X
22-
##

#
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/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
59+
# within the Gradle project.
