If your /bin/sh is 28 # noncompliant, but you have some other compliant shell such as ksh or 29 # bash, then to run this script, type that shell name before the whole 30 # command line, like: 31 # 32 # ksh gradlew 33 # 34 # Busybox and similar reduced shells will NOT work, because this script 35 # requires all of these POSIX shell features: 36 # * functions; 37 # * expansions «$var», «${var}», «${var:-default}», «${var+SET}», 38 # «${var#prefix}», «${var%suffix}», and «$( cmd )»; 39 # * compound commands having a testable exit status, especially «case»; 40 # * various built-in commands including «command», «set», and «ulimit». 41 # 42 # Important for patching: 43 # 44 # (2) This script targets any POSIX shell, so it avoids extensions provided 45 # by Bash, Ksh, etc; in particular arrays are avoided. 46 # 47 # The "traditional" practice of packing multiple parameters into a 48 # space-separated string is a well documented source of bugs and security 49 # problems, so this is (mostly) avoided, by progressively accumulating 50 # options in "$@", and eventually passing that to Java. 51 # 52 # Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS, 53 # and GRADLE_OPTS) rely on word-splitting, this is performed explicitly; 54 # see the in-line comments for details. 55 # 56 # There are tweaks for specific operating systems such as AIX, CygWin, 57 # Darwin, MinGW, and NonStop. 58 # 59 # (3) This script is generated from the Groovy template 60 # https://github.com/gradle/gradle/blob/3d91ce3b8caaf77ad09f381f43615b715b53f72c/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt 61 # within the Gradle project. 62 # 63 # You can find Gradle at https://github.com/gradle/gradle/. 64 # 65 ############################################################################## 66 67 # Attempt to set APP_HOME 68 69 # Resolve links: $0 may be a link 70 app_path=$0 71 72 # Need this for daisy-chained symlinks. 73 while 74 APP_HOME=${app_path%"${app_path##*/}"} # leaves a trailing /; empty if no leading path 75 [ -h "$app_path" ] 76 do 77 ls=$( ls -ld "$app_path" ) 78 link=${ls#*' -> '} 79 case $link in #( 80 /*) app_path=$link ;; #( 81 *) app_path=$APP_HOME$link ;; 82 esac 83 done 84 85 # This is normally unused 86 # shellcheck disable=SC2034 87 APP_BASE_NAME=${0##*/} 88 # Discard cd standard output in case $CDPATH is set (https://github.com/gradle/gradle/issues/25036) 89 APP_HOME=$( cd -P "${APP_HOME:-./}" > /dev/null && printf '%s\n' "$PWD" ) || exit 90 91 # Use the maximum available, or set MAX_FD != -1 to use that value. 92 MAX_FD=maximum 93 94 warn () { 95 echo "$*" 96 } >&2 97 98 die () { 99 echo 100 echo "$*" 101 echo 102 exit 1 103 } >&2 104 105 # OS specific support (must be 'true' or 'false'). 106 cygwin=false 107 msys=false 108 darwin=false 109 nonstop=false 110 case "$( uname )" in #( 111 CYGWIN* ) cygwin=true ;; #( 112 Darwin* ) darwin=true ;; #( 113 MSYS* | MINGW* ) msys=true ;; #( 114 NONSTOP* ) nonstop=true ;; 115 esac 116 117 118 119 # Determine the Java command to use to start the JVM. 120 if [ -n "$JAVA_HOME" ] ; then 121 if [ -x "$JAVA_HOME/jre/sh/java" ] ; then 122 # IBM's JDK on AIX uses strange locations for the executables 123 JAVACMD=$JAVA_HOME/jre/sh/java 124 else 125 JAVACMD=$JAVA_HOME/bin/java 126 fi 127 if [ ! -x "$JAVACMD" ] ; then 128 die "ERROR: JAVA_HOME is set to an invalid directory: $JAVA_HOME 129 130 Please set the JAVA_HOME variable in your environment to match the 131 location of your Java installation." 132 fi 133 else 134 JAVACMD=java 135 if ! command -v java >/dev/null 2>&1 136 then 137 die "ERROR: JAVA_HOME is not set and no 'java' command could be found in your PATH. 138 139 Please set the JAVA_HOME variable in your environment to match the 140 location of your Java installation." 141 fi 142 fi 143 144 # Increase the maximum file descriptors if we can. 145 if !
