# 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/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
