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
