| 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
