JavaFX 應用程序啟動失敗

Question

我最近使用 Java 11 創建了一個 IntelliJ JavaFX 項目並嘗試啟動模板，但出現此錯誤：

"C:\Program Files\Java\jdk-11.0.6\bin\java.exe" --add-modules javafx.base,javafx.graphics --add-reads javafx.base=ALL-UNNAMED --add-reads javafx.graphics=ALL-UNNAMED "-javaagent:C:\Program Files\JetBrains\IntelliJ IDEA Community Edition 2019.3.1\lib\idea_rt.jar=56068:C:\Program Files\JetBrains\IntelliJ IDEA Community Edition 2019.3.1\bin" -Dfile.encoding=UTF-8 -classpath C:\Users\jan\Desktop\Programmieren\Java\Other\RaspberryShell\out\production\RaspberryShell -p "C:\Program Files\Java\javafx-sdk-14.0.2.1\lib\javafx.base.jar;C:\Program Files\Java\javafx-sdk-14.0.2.1\lib\javafx.graphics.jar" sample.Main

就像我說的那樣，IntelliJ 為我創建了它。 有人有想法嗎？ 編輯：我正在使用 JavaFX 14

Answer 1

好的，我想我自己找到了解決方案。 我安裝了 JavaFX11 並將其選為庫。 然后我將 vm 選項添加到運行配置(C:\Program Files\Java\javafx-sdk-11.0.2\lib) ，但我得到了另一個錯誤。 我通過將 javafx sdk 的路徑更改為不需要管理員權限的文件夾來解決問題。 （例如在 localappdata 中）
