 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/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
 59 | #       within the Gradle project.
