#

#   Gradle start up script for POSIX generated by Gradle.
#

#   Important for running:
#

#   (1)
You need
a POSIX
-
compliant shell
to run
this script.
If your
/bin/
sh is
#       noncompliant, but you have some other compliant shell such as ksh or
#       bash, then to run this script, type that shell name before the whole
#       command line, like:
#

#           ksh Gradle
#

#       Busybox and similar reduced shells will NOT work, because this script
#       requires all of these POSIX shell features:
#         *
functions;
#         * expansions «$var», «${
var}», «${
var:-default}», «${
var+SET}»,
#           «${
var#prefix}», «${
var%suffix}», and «
$( cmd )
»;
#         *
compound commands
having a
testable exit
status, especially «case»;
#         *
various built
-
in commands
including «command», «set», and «ulimit».
#

#   Important for patching:
#

#   (2)
This script
targets any
POSIX shell, so
it avoids
extensions provided
#       by Bash, Ksh, etc; in particular arrays are avoided.
#

#       The "traditional" practice of packing multiple parameters into a
#       space-separated string is a well documented source of bugs and security
#       problems, so this is (mostly) avoided, by progressively accumulating
#       options in "$@", and eventually passing that to Java.
#

#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
#       see the in-line comments for details.
#

#       There are tweaks for specific operating systems such as AIX, CygWin,
#       Darwin, MinGW, and NonStop.
#

#   (3)
This script
is generated
from the
Groovy
template
#       https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
#       within the Gradle project.
