你好我正在尝试用launch4j maven插件包装一个javaFX-jar。

但执行失败：

看起来exe找不到jfxruntime。如果我用“java -jar ...”启动程序，它工作正常。

这是我的 pom.xml 的一部分

我怀疑问题出在您指定的 JRE 版本上。JavaFX（2.2 版）直到 1.7 更新 6 才与 JRE 捆绑在一起。我认为您的 minVersion 设置可能接受更新 5 或更早版本的 JRE，并且未安装（正确）JavaFX 库。尝试指定<minVersion>1.7.0_09</minVersion>并查看是否有效。

我似乎记得，如果您有 64 位更新 6 和 32 位更新 5，那么即使 64 位会更好，launcher4j 也会选择 32 位版本。这可以解释为什么它在您的开发环境中有效，但在构建时无效。

除此之外，您的 POM 配置看起来与我的几乎相同，可以正常工作。
