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.
