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.
