  19. # Gradle start up script for POSIX generated by Gradle.
  20. #
  21. # Important for running:
  22. #
  23. # (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
  24. # noncompliant, but you have some other compliant shell such as ksh or
  25. # bash, then to run this script, type that shell name before the whole
  26. # command line, like:
  27. #
  28. # ksh Gradle
  29. #
  30. # Busybox and similar reduced shells will NOT work, because this script
  31. # requires all of these POSIX shell features:
  32. # * functions;
  33. # * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
  34. # «${var#prefix}», «${var%suffix}», and «$( cmd )»;
  35. # * compound commands having a testable exit status, especially «case»;
  36. # * various built-in commands including «command», «set», and «ulimit».
  37. #
  38. # Important for patching:
  39. #
  40. # (2) This script targets any POSIX shell, so it avoids extensions provided
  41. # by Bash, Ksh, etc; in particular arrays are avoided.
  42. #
  43. # The "traditional" practice of packing multiple parameters into a
  44. # space-separated string is a well documented source of bugs and security
  45. # problems, so this is (mostly) avoided, by progressively accumulating
  46. # options in "$@", and eventually passing that to Java.
  47. #
  48. # Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
  49. # and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
  50. # see the in-line comments for details.
  51. #
  52. # There are tweaks for specific operating systems such as AIX, CygWin,
  53. # Darwin, MinGW, and NonStop.
  54. #
  55. # (3) This script is generated from the Groovy template
  56. # https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
  57. # within the Gradle project.
