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

 1 | # Java Launch Wrapper (v1.4.3)
 2 | 
 3 | ## 有什么用？
 4 | 
 5 | 如果你的 Windows 系统启用了 *Beta 版：使用Unicode UTF-8提供全球语言支持*，Java 可能会在读取命令行参数时使用错误的编码进行解码，导致一系列问题。
 6 | 
 7 | Bug 参考 [JDK-8272352](https://bugs.openjdk.org/browse/JDK-8272352)，已在 Java19 修复
 8 | 
 9 | 使用此 Wrapper 可用于修复 **Class Path**, **-D 参数** 和 **App 参数** 中的乱码，解决大部分因此Bug无法运行的情况。
10 | 
11 | ## 怎么用？
12 | 
13 | 更改 Java 启动命令行，在 JVM 参数和主类之间插入`-jar java_launch_wrapper.jar`即可（需要 Java >= 1.6）。
14 | 
15 | 例如：
16 | 
17 | > 原命令行：
18 | > 
19 | >     java -cp "路径1";"路径2" MainClass 参数1 参数2
20 | > 
21 | > 更改后：
22 | > 
23 | >     java -cp "路径1";"路径2" -jar "java_launch_wrapper.jar" MainClass 参数1 参数2
24 | 
25 | **注意：** 
26 | 
27 | 1. 除`-jar`外原命令中的其他 jvm 选项可以直接保留，若原命令行中使用`-jar`则应该改为 ClassPath + MainClass 的形式。
28 | 2. Wrapper 会将动态链接库释放到系统临时目录，若系统的临时文件路径中也存在特殊字符，可以在 -jar 前添加 `-Doolloo.jlw.tmpdir="<自定义临时文件路径>"` 更改。
29 |    在这种情况下需要保证此路径存在且无特殊字符。
30 | 3. 仅在 Windows 平台可用，因为这个 Bug 是 Windows 独家。

34 | ## 更新记录
35 | 
36 | ### V1.4
37 | 
38 | - 修复未捕获`UnsatisfiedLinkError`未被捕获导致备用方案未被使用的问题
39 | - 支持 arm64 以及其他无法正确加载 native 库的情况（使用 powershell CIM cmdlet）
40 | - 解析 `-D 参数` 并覆盖到 JVM 的 System.Properties
41 | - 使用 zig 编译 native 库，去除无关依赖，减小库体积
42 | - 移除 dll 文件的 crc 校验
43 | - 移除 `-Doolloo.jlw.silent` 选项，改为设置 `-Doolloo.jlw.debug=true` 启用 wrapper 调试信息
44 | 
45 | ### V1.3
46 | 
47 | - 增加修改临时文件路径的启动参数
48 | - 修复 dll 被占用导致无法启动多个进程的问题
49 | - 增加 dll 文件校验
50 | - 增加必要的调试信息输出，可设置 `-Doolloo.jlw.silent=true` 关闭
51 | 
52 | ### V1.2
53 | 
54 | - 修复对std库的依赖问题
55 | - 修复字符编码问题
56 | - 将获取到的classpath写入jvm系统属性`java.class.path`以确保被包装应用能读取到正确的值
57 | 
58 | ### V1.1
59 | 
60 | - 修复对 Java9 - Java15 的支持。
