Launch4J 未获取捆绑的 JRE

Question

我知道有很多类似的问题，但我无法使其与这些解决方案一起工作。

我正在使用Launch4J 3.50，并尝试使用由adoptium提供的捆绑JRE运行exe https://adoptium.net/temurin/releases/?version=11

通过从 bat 文件启动 exe，使用 SET Launch4j=debug 选项，我能够生成此日志文件：

Version:    3.50

Error msg:  This application requires a Java Runtime Environment 11.0.0 - 11.900.900

这是我的根文件夹：

这是我的服务文件夹：

这是我的 Launch4J xml 配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<launch4jConfig>
  <dontWrapJar>false</dontWrapJar>
  <headerType>gui</headerType>
  <jar>C:\Users\jhonnyD\Desktop\launch4j\service\jars\MyApp.jar</jar>

    <minVersion>11.0.0</minVersion>
    <maxVersion>11.900.900</maxVersion>
  </jre>
</launch4jConfig>

当我在安装了 java 的计算机上运行它时，exe 可以运行。显然它正在从系统中获取 jre。当我在缺少 java 的计算机上运行此程序时，我得到：

This application requires a Java Runtime Environment 11.0.0 - 11.900.900

奇怪的是，日志指出发现了捆绑的 javaw.exe：

Check launcher: D:\service\adoptium\bin\javaw.exe (OK)

我在这里错过了什么吗？

Answer 1

似乎您需要将标签

<requiresJdk>

中的选项从

true

更改为

false

。 我刚刚在我的应用程序上使用类似的配置测试了 launch4j 3.50，它在这个最小配置下工作得很好：

<?xml version="1.0" encoding="UTF-8"?>
<launch4jConfig>
  <dontWrapJar>false</dontWrapJar>
  <headerType>gui</headerType>
  <jar>C:\launch4j-3.50-win32\service\jars\dvm.jar</jar>
  <outfile>C:\launch4j-3.50-win32\dvm.exe</outfile>
  <errTitle></errTitle>

    <requiresJdk>false</requiresJdk>
    <requires64Bit>false</requires64Bit>

    <maxVersion></maxVersion>
  </jre>
</launch4jConfig>

Answer 2

Estive como um Problema identico hoje and descobri que Launch4j 3.50 não inseri litermente o jre por ele apenas pede o caminho que semper vai aceder para encontrar o jre, então usei o inosetup para criar um setup and adicionar o jre que possuo, deste jeito so adicionei o nome da Pasta do jre no meuprojecto e funcionou no meu caso
