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 58 # https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt 59 # within the Gradle project. 60 # 61 # You can find Gradle at https://github.com/gradle/gradle/. 62 # 63 ############################################################################## 64 65 # Attempt to set APP_HOME 66 67 # Resolve links: $0 may be a link 68 app_path=$0 69 70 # Need this for daisy-chained symlinks. 71 while 72 APP_HOME=${app_path%"${app_path##*/}"} # leaves a trailing /; empty if no leading path 73 [ -h "$app_path" ] 74 do 75 ls=$( ls -ld "$app_path" ) 76 link=${ls#*' -> '} 77 case $link in #( 78 /*) app_path=$link ;; #( 79 *) app_path=$APP_HOME$link ;; 80 esac 81 done 82 83 APP_HOME=$( cd "${APP_HOME:-./}" && pwd -P ) || exit 84 85 APP_NAME="Gradle" 86 APP_BASE_NAME=${0##*/} 87 88 # Add default JVM options here.
