Launch4j:此应用程序需要使用maven的Java Runtime Environment 1.8.0_161

Question

我正在使用launch4j maven插件为我的应用程序生成.exe。我也想嵌入一个捆绑的JRE。我在安装了java 1.8.0_161的电脑上成功地实现了它。我现在的问题是，当我试图从一台没有安装java的虚拟机上执行.exe时，我出现了这个错误

CryptoAlertNews: This application requires a Java Runtime Environment 1.8.0_161

为什么会发生这种事——我做错了什么？这就是我在pom.xml中的内容：

Answer 1

您必须知道Launch4J并没有嵌入JRE，而是在运行时引用JRE。

<path>内容应该是在执行EXE时指向JRE的路由。

您可以使用ZIP分发应用程序，然后将文件夹jre放在根文件夹中，将.EXE放在同一文件夹中。

然后您的ZIP内容如下：

|jre (with the contents of the jre uncompressed, including bin directory)
|app.exe

您可以在这里找到一个与您类似的问题：如何将JRE与Launch4j捆绑在一起？
