【问题描述】：

我有一个使用 Java SDK 1.8 成功构建和运行的 JavaFX 应用程序。我正在尝试将其移至 Java 11，最终目标是使用 Java 14，并且无法创建可运行的 jar。为了尝试理解这个过程，我下载了 javafx helloFX 示例，并尝试按照 https://openjfx.io/openjfx-docs/#modular 的 Maven 说明进行操作。当我运行 mvn clean javafx:jlink 时出现错误：

谁能指出我正确的方向，因为我无法理解这个问题。

【解决方案1】：

提供的示例与教程所述的结构不同。 Maven 版本已在 CommandLine 文件夹下更新。如果您转到：..\CommandLine\Modular\Maven\helloFX 并输入命令 mvn clean javafx:run, clean javafx:jlink, target\hellofx\bin\launcher，它将按照教程中的说明运行。
