    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.
