How can you package an executable jar with a portable JRE?
提问by Penchant
I want to be able to distribute by executable JAR without having to make the user upgrade to the latest version of the JRE. How can I package a JRE into the JAR so that they can run the jar with no JRE installed on their system?
我希望能够通过可执行 JAR 进行分发，而不必让用户升级到最新版本的 JRE。如何将 JRE 打包到 JAR 中，以便他们可以在系统上未安装 JRE 的情况下运行 jar？

Put Java Portablein a sub-directory and launch your jar using a batch/bash script or Launch4j.
将Java Portable放在子目录中，然后使用批处理/bash 脚本或Launch4j启动您的 jar 。

Ten years later I ran into the same problem, and after several days looking, apparently there is still no solution, this is the best thing I have found:
十年后我遇到了同样的问题，看了几天，显然仍然没有解决方案，这是我发现的最好的事情：

I found another way to do it, based on Inno Setup and NetBeans, it often appears as a result of searches about converting jar to exe. Everything is done using Native Packaging in NetBeans IDE.
我找到了另一种方法，基于 Inno Setup 和 NetBeans，它经常出现在搜索将 jar 转换为 exe 的结果中。一切都是在 NetBeans IDE 中使用本机打包完成的。
The result is a standalone .exe installer (YourProjectName.exe) that creates a folder in AppData\Local\YourProjectName. In that folder you will find the launcher, which is an .exe, and also all the necessary files to run the software without installing Java.
结果是一个独立的 .exe 安装程序 (YourProjectName.exe)，它在AppData\Local\YourProjectName中创建一个文件夹。在该文件夹中，您将找到启动程序，它是一个 .exe，以及无需安装 Java 即可运行该软件的所有必要文件。
You should use exactly the same tools versions that says in the article, otherwise it does not work, at least not for me. The other thing that is not clear is that your project must be a Java with Ant proyect, at least I did not find how to do it with Gradle or Maven.
你应该使用文章中所说的完全相同的工具版本，否则它不起作用，至少对我来说不是。另一件不清楚的是，你的项目必须是带有 Ant 项目的 Java，至少我没有找到如何用 Gradle 或 Maven 来做。
Also, I had to install an old i586version of Java (I tried JDK 1.8 i586 and it worked) because JDK 13 causes errors (missing dll's) when trying to run the software. Although I only tried with JDK 13 x64, maybe architecture is the problem and not the version. Whatever, similar happened to NetBeans 11, the .exe launcher did not work, however when locating and executing the .jar it did work. So I ended up using NetBeans 8.
另外，我必须安装旧的i586版本的 Java（我尝试了 JDK 1.8 i586 并且它工作了），因为 JDK 13 在尝试运行该软件时会导致错误（缺少 dll）。虽然我只尝试过 JDK 13 x64，但也许架构是问题而不是版本。不管怎样，与 NetBeans 11 类似，.exe 启动器不起作用，但是在定位和执行 .jar 时它确实起作用了。所以我最终使用了 NetBeans 8。
