21 ## Gradle start up script for UN*X |
23 # Gradle start up script for POSIX generated by Gradle. |
22 ## |
24 # |
|
25 # Important for running: |
|
26 # |
|
27 # (1) You need a POSIX-compliant shell to run this script. 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 Gradle |
|
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 |
