| # 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 |
| # within the Gradle project. |
