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