Question

在使用launch4j将我的jar文件转换为exe后，它给了我一个JNI错误，告诉我要检查我的安装，然后再试一次，它给我另一个警告，指出发生了Java异常。

我尝试了不同的方式，例如选择不同的选项，但仍然无法正常工作。

这是日志：

这意味着launch4j用于运行程序的JVM版本比编译类fluidDynamicsProject / FluidDynamicSerial的编译器版本要新。您可以尝试在launchj4配置文件中设置最低版本：

<?xml version="1.0" encoding="UTF-8"?>
<launch4jConfig>
  ...
  <jre>
    ...
    <minVersion>11.0</minVersion>
    ...
  </jre>
</launch4jConfig>

请注意，launch4j可能不支持Java的最新版本。

否则，您可以降低用于编译类的目标版本。
