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 ${applicationName} # # 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 ${optsEnvironmentVar}) 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/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt # within the Gradle project. #<% /* # ... and if you're reading this, this IS the template just mentioned. # # This template is processed by # https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/java/org/gradle/api/internal/plugins/UnixStartScriptGenerator.java # # Gradle is a meta-build system used by the project that you're building # or installing. It's like autoconf but for projects that are written in # Java and related languages. It's also used to build parts of the Gradle # project itself. # # The Groovy template language is run in two phases. # # 1. Any character following \ is passed unmodified through to the # next phase, while the \ is removed. Any other $ followed by # varName or {varName} is replaced by the value of that variable. # # 2. The result of the first phase is parsed and run in a similar # manner to JSP or MASON or PHP: anything within < % ... % > is a # code block, anything else is sent as output, subject to the # flow imposed by any code segments. # # 3. The "output" is a POSIX shell script, which has its own ideas about # escaping with backslashes, so to get «\» you need to write «\\\\» # and to get «$» you need to write «\\\$». # # For more details about the Groovy Template Engine, see # https://docs.groovy-lang.org/next/html/documentation/ section §3.15 # (Template Engines) for details. # # (An example invocation of this template is from # https://github.com/gradle/gradle/blob/HEAD/subprojects/build-init/src/main/java/org/gradle/api/tasks/wrapper/Wrapper.java # within the Gradle project, which builds "gradlew".) # */ %> # You can find Gradle at https://github.com/gradle/gradle/. # ############################################################################## # Attempt to set APP_HOME # Resolve links: \$0 may be a link app_path=\$0 # Need this for daisy-chained symlinks. while APP_HOME=\${app_path%"\${app_path##*/}"} # leaves a trailing /; empty if no leading path [ -h "\$app_path" ] do ls=\$( ls -ld "\$app_path" ) link=\${ls#*' -> '} case \$link in #( /*) app_path=\$link ;; #( *) app_path=\$APP_HOME\$link ;; esac done # This is normally unused # shellcheck disable=SC2034 APP_BASE_NAME=\${0##*/} APP_HOME=\$( cd "\${APP_HOME:-./}${appHomeRelativePath}" && pwd -P ) || exit # Use the maximum available, or set MAX_FD != -1 to use that value.
