#

#   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/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt

#       within the Gradle project.
