20+ #
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.
