22+ #
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.
