| 23 | +# Gradle start up script for POSIX generated by Gradle. |
| 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/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt |
