Inno Setup - 设置 Java 环境变量 [英] Inno Setup - Setting Java Environment Variable

问题描述

我正在使用 Inno Setup 为我正在处理的项目制作安装程序，我需要它来设置 java 环境变量，这样当他们运行 cmd 时就不会得到 java not found 错误，或类似的东西.

I am using Inno Setup to make an installer for a project I am working on, and I need it to set the java environment variable, so that when they run cmd they don't get a java not found error, or something like that.

我发现了一些与 Inno Setup 和设置环境变量相关的其他帖子，但是有人知道这个实例的特定内容吗?

I have found a few other posts related to Inno Setup and the setting environment variables, but does anyone know something specific to this instance?

推荐答案

假设 Java 安装在其默认位置程序文件/Java 中，这样的情况应该适用于您的情况:

Assuming Java is installed in its default location program files/Java, something like this should work in your case:

[Registry]
; set PATH
Root: HKCU; Subkey: "Environment"; ValueType:string; ValueName:"PATH"; ValueData:"{olddata};{pf}Javain"; Flags: preservestringtype
; set JAVA_HOME
Root: HKCU; Subkey: "Environment"; ValueType:string; ValueName:"JAVA_HOME"; ValueData:"{pf}Java"; Flags: preservestringtype

[Setup]
; Tell Windows Explorer to reload the environment
ChangesEnvironment=yes

我不确定您要设置哪个环境变量——PATH 或 JAVA_HOME——所以我都添加了它们.

I'm not sure which environment variable you want to set -- PATH or JAVA_HOME -- so I've added them both.

不需要更改 PATH，因为 Java 安装程序倾向于将自身添加到路径中；IIRC 它将 java.exe 和 javaw.exe 复制到系统目录之一.

Changing PATH shouldn't be necessary since the Java installer tends to add itself to the path; IIRC it copies java.exe and javaw.exe to one of the system directories.
