21 # Gradle start up script for POSIX generated by Gradle.
23 # Important for running:
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
32 # Busybox and similar reduced shells will NOT work, because this script
33 # requires all of these POSIX shell features:
35 # * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
36 # «${var#prefix}», «${var%suffix}», and «$( cmd )»;
37 # * compound commands having a testable exit status, especially «case»;
38 # * various built-in commands including «command», «set», and «ulimit».
40 # Important for patching:
42 # (2) This script targets any POSIX shell, so it avoids extensions provided
43 # by Bash, Ksh, etc; in particular arrays are avoided.
45 # The "traditional" practice of packing multiple parameters into a
46 # space-separated string is a well documented source of bugs and security
47 # problems, so this is (mostly) avoided, by progressively accumulating
48 # options in "$@", and eventually passing that to Java.
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.
54 # There are tweaks for specific operating systems such as AIX, CygWin,
55 # Darwin, MinGW, and NonStop.
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.
