我刚刚安装了SDK 11，并使用了来自maven的Javafx。我的pom如下。

我正在使用WebView，它可以帮助我查看Facebook数据并下载所需的内容。

请找到以下异常：

我添加了以下虚拟机--module-path /Applications/javafx-sdk-11.0.2/lib --add-modules=javafx.controls,javafx.fxml,javafx.base

似乎我从过去2小时开始尝试使此代码正常工作。代码中没有编译错误。我犯了什么错误？

Answer 1

也许您可以检查此问题https://github.com/GSI-CS-CO/chart-fx/issues/6
帮助我解决了这个问题
只需将这些内容附加到您的配置中

--module-path /path/to/javafx-sdk-11.0.2/lib --add-modules=javafx.swing,javafx.graphics,javafx.fxml,javafx.media,javafx.web --add-reads javafx.graphics=ALL-UNNAMED --add-opens javafx.controls/com.sun.javafx.charts=ALL-UNNAMED --add-opens javafx.graphics/com.sun.javafx.iio=ALL-UNNAMED --add-opens javafx.graphics/com.sun.javafx.iio.common=ALL-UNNAMED --add-opens javafx.graphics/com.sun.javafx.css=ALL-UNNAMED --add-opens javafx.base/com.sun.javafx.runtime=ALL-UNNAMED

也许可行

Answer 2

您必须添加--add-exports javafx.graphics/com.sun.javafx.sg.prism=ALL-UNNAMED，它应该可以工作！

Answer 3

就我而言，问题是在从jdk13转到jdk14之后出现的。因此，最好将其添加到编辑器上的VM中：

--module-path /Applications/javafx-sdk-11.0.2/lib --add-modules=javafx.controls,javafx.fxml,javafx.base --add-exports javafx.graphics/com.sun.javafx.sg.prism=ALL-UNNAMED

或者只需完成--add-exports javafx.graphics/com.sun.javafx.sg.prism=ALL-UNNAMED

超类访问检查失败：com.sun.javafx.sg.prism.web.NGWebView类
