NoClassDefFoundError：龙卷风/视图

问题描述 投票：0回答：1

我已经制作了一个JavaFX / TornadoFX应用程序，用gradle构建了一个jar，它的工作正常。现在，我使用launch4j gui将我的工作jar打包到一个exe中，并且打包过程成功。问题是，当我在Launch4j gui中使用“测试”按钮运行Exe时，得到以下堆栈跟踪：

Executing: C:\Users\xx\Documents\EXEkonfig\xxx.exe

我的mainClass看起来像这样：

  class CreatorMain : App() {
  override val primaryView = CreatorScreen::class
  var decorator: JFXDecorator by singleAssign()
  val view = find(primaryView, scope)

init {
    // reloadStylesheetsOnFocus()
    // reloadViewsOnFocus()

     CreatorUtil.setLocale(Locale.GERMAN)
    importStylesheet("/styles/RootFrame.css")
}

override fun createPrimaryScene(view: UIComponent) = Scene(decorator,      1250.0, 500.0)
        .apply {
            FX.primaryStage.centerOnScreen()
        }

   override fun start(stage: Stage) {
    decorator = JFXDecorator(stage, view.root)
    val logo=ImageView(Image("/img/creatorlogo16.png"))

    decorator.setGraphic(logo)


    stage.icons += Image("/img/creatorlogo16.png")
    stage.icons += Image("/img/creatorlogo32.png")
    stage.icons += Image("/img/creatorlogo64.png")
    super.start(stage)
  }

我缺少明显的东西吗？

您在类中引用了JFoenix（JFXDecorator），但尚未将其包含在launch4j配置中。 TornadoFX还需要在类路径上实现javafx.json，而不仅仅是API。我们使用org.glassfish.javax.json，因此您应该使用相同的名称。

我也建议您将应用程序类放在一个包中，不建议使用默认包。

最后，您可以研究FXLauncher作为launch4j的替代方法。这还使您能够无缝部署应用程序的新版本，并在用户重新启动应用程序时自动更新它：）
