    21 ##  Gradle start up script for UN*X
    23 #   Gradle start up script for POSIX generated by Gradle.
    22 ##
    24 #
       
    25 #   Important for running:
       
    26 #
       
    27 #   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
       
    28 #       noncompliant, but you have some other compliant shell such as ksh or
       
    29 #       bash, then to run this script, type that shell name before the whole
       
    30 #       command line, like:
       
    31 #
       
    32 #           ksh Gradle
       
    33 #
       
    34 #       Busybox and similar reduced shells will NOT work, because this script
       
    35 #       requires all of these POSIX shell features:
       
    36 #         * functions;
       
    37 #         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
       
    38 #           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
       
    39 #         * compound commands having a testable exit status, especially «case»;
       
    40 #         * various built-in commands including «command», «set», and «ulimit».
       
    41 #
       
    42 #   Important for patching:
       
    43 #
       
    44 #   (2) This script targets any POSIX shell, so it avoids extensions provided
       
    45 #       by Bash, Ksh, etc; in particular arrays are avoided.
       
    46 #
       
    47 #       The "traditional" practice of packing multiple parameters into a
       
    48 #       space-separated string is a well documented source of bugs and security
       
    49 #       problems, so this is (mostly) avoided, by progressively accumulating
       
    50 #       options in "$@", and eventually passing that to Java.
       
    51 #
       
    52 #       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
       
    53 #       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
       
    54 #       see the in-line comments for details.
       
    55 #
       
    56 #       There are tweaks for specific operating systems such as AIX, CygWin,
       
    57 #       Darwin, MinGW, and NonStop.
       
    58 #
       
    59 #   (3) This script is generated from the Groovy template
       
    60 #       https://github.com/gradle/gradle/blob/3d91ce3b8caaf77ad09f381f43615b715b53f72c/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
       
    61 #       within the Gradle project.
