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 gradlew # # 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 file is maintained by the Gradle Wrapper Neo project. It compiles # gradle/wrapper/GradleWrapperNeo.java on demand and launches the Wrapper # without storing a Wrapper JAR in the project. # # Documentation and updates: https://github.com/Glavo/gradle-wrapper-neo # ############################################################################## # Determine the directory containing this launcher # Resolve links: $0 may be a link app_path=$0 # Need this for daisy-chained symlinks. while LAUNCHER_HOME=${app_path%"${app_path##*/}"} # leaves a trailing /; empty if no leading path [ -h "$app_path" ] do ls=$( ls -ld "$app_path" ) link=${ls#*' -> '} case $link in #( /*) app_path=$link ;; #( *) app_path=$LAUNCHER_HOME$link ;; esac done # This is normally unused # shellcheck disable=SC2034 APP_BASE_NAME=${0##*/} # Discard cd standard output in case $CDPATH is set (https://github.com/gradle/gradle/issues/25036) LAUNCHER_HOME=$( cd -P "${LAUNCHER_HOME:-./}" > /dev/null && printf '%s\n' "$PWD" ) || exit # Use the maximum available, or set MAX_FD != -1 to use that value.
