我需要支持无法正常构建和运行的旧版 JavaFX 应用程序。该应用程序相当复杂，因此我做了简单的“Hello world”项目，而不是对其进行试验。我也无法编译它。我希望有人能指出我的错误。
我从这个例子开始，JavaFX 文档中提到了这个例子： https://github.com/openjfx/samples
<?php
session_start();
//header("Cache-Control: no-cache");
//header("Pragma: no-cache");
include 'loginClass.php';
$login = new userLogin();
if(isset($_POST['submit'])){
$login->login($_POST);
}
?>

好吧，可能 pom 文件有点过时了，缺少 maven.compiler.source 和 maven.compiler.target。让我们添加它们：

让我们复制粘贴我之前在 stackoverflow 上找到的一些 pom 片段。我的理解是，它会指示 maven-assembly-plugin 制作自定义 jar，除了普通的 JAR 之外，还包含其中的所有依赖项。

我现在已经没有想法了。我做错了什么？
答案 0 :(得分：2)
您试图同时做几件事，这绝不是一个好主意，而且您没有密切关注文档。您是否尝试按照文档中的说明使用 mvn clean javafx:run 运行您的示例？
将遗留应用程序移植到最新的 JDK/JavaFX 时，您应该做的第一件事是编译它并使用 JavaFX Maven 插件运行它。如果它是为 JDK8 编写的旧应用程序，并且它包含 JavaFX，那么这可能已经是一些挑战，因为有一些 API 更改和其他事情。
一旦您解决了这些问题并让您的应用运行起来，您就可以开始考虑打包了。现在的 JavaFX 应用程序不应该只是被扔到一些大的 jar 文件中，因为这只会导致很多其他问题。相反，您应该考虑使用 jpackage 来创建合适的应用程序安装程序。你可能想看看这里：https://github.com/dlemmermann/JPackageScriptFX（注意：我对此有偏见。）
