Javafx 部署失败。在指定位置找不到 JDK 工件 : C:\Program Files\Java\jre1. 8.0

Question

这是我在 JavaFX 上的第一个项目。我正在使用 eclipse 将项目构建为 exe 文件。我快完成了。但我不知道我现在遇到的问题是什么。

我的 ant 构建文件代码在这里。

Answer 1

告诉eclipse使用JDK而不是JRE，因为jre没有所有的库jar文件。

在 Eclipse 中，选择“窗口”菜单->“首选项”。然后选择Java->安装的JRE。然后单击“添加...”，选择“标准 VM”，然后单击“下一步”。在 JRE 主目录中，导航到已安装 JDK 的文件夹 (c:\Program Files\Java\jdk1.6.0_21)。
