將 JavaFX 專案建置到 jar 檔案中。

請幫我弄清楚。我在 JavaFX 中建立了一個專案並從 IDE 啟動它，沒有出現錯誤。我為此專案創建了一個 jar 文件，當我從 IDE 啟動該 jar 檔案時，出現錯誤： /usr/lib/jvm/java-8-oracle/bin/java -Dfile.encoding=UTF-8 -jar /home/artem/IdeaProjects/Address_book/out/artifacts/Address_book_jar/Address_book.jar Exception in Application start method java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at com.sun.javafx.application.LauncherImpl.launchApplicationWithArgs(LauncherImpl.java:389) at com.sun.javafx.application.LauncherImpl.launchApplication(LauncherImpl.java:328) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at sun.launcher.LauncherHelper$FXHelper.main(LauncherHelper.java:767) Caused by: java.lang.RuntimeException: Exception in Application start method at com.sun.javafx.application.LauncherImpl.launchApplication1(LauncherImpl.java:917) at com.sun.javafx.application.LauncherImpl.lambda$launchApplication$155(LauncherImpl.java:182) at java.lang.Thread.run(Thread.java:745) Caused by: javafx.fxml.LoadException: file:/home/artem/IdeaProjects/Address_book/out/artifacts/Address_book_jar/Address_book.jar!/fxml/main.fxml at javafx.fxml.FXMLLoader.constructLoadException(FXMLLoader.java:2601) at javafx.fxml.FXMLLoader.loadImpl(FXMLLoader.java:2579) at javafx.fxml.FXMLLoader.loadImpl(FXMLLoader.java:2441) at javafx.fxml.FXMLLoader.load(FXMLLoader.java:2409) at Main.start(Main.java:15) at com.sun.javafx.application.LauncherImpl.lambda$launchApplication1$162(LauncherImpl.java:863) at com.sun.javafx.application.PlatformImpl.lambda$runAndWait$175(PlatformImpl.java:326) at com.sun.javafx.application.PlatformImpl.lambda$null$173(PlatformImpl.java:295) at java.security.AccessController.doPrivileged(Native Method) at com.sun.javafx.application.PlatformImpl.lambda$runLater$174(PlatformImpl.java:294) at com.sun.glass.ui.InvokeLaterDispatcher$Future.run(InvokeLaterDispatcher.java:95) at com.sun.glass.ui.gtk.GtkApplication._runLoop(Native Method) at com.sun.glass.ui.gtk.GtkApplication.lambda$null$49(GtkApplication.java:139) ... 1 more Caused by: java.lang.IllegalStateException: Location is not set. at javafx.fxml.FXMLLoader.loadImpl(FXMLLoader.java:2434) at javafx.fxml.FXMLLoader.load(FXMLLoader.java:2409) at controllers.MainController.initialize(MainController.java:199) at javafx.fxml.FXMLLoader.loadImpl(FXMLLoader.java:2548) ... 12 more Exception running application Main 即 抱怨 fxmlLoader.load()。主類別： import controllers.MainController; import javafx.application.Application; import javafx.fxml.FXMLLoader; import javafx.scene.Parent; import javafx.scene.Scene; import javafx.stage.Stage; public class Main extends Application { @Override public void start(Stage primaryStage) throws Exception { FXMLLoader fxmlLoader = new FXMLLoader(); fxmlLoader.setLocation(getClass().getResource("/fxml/main.fxml")); Parent fxmlMain = fxmlLoader.load(); MainController mainController = fxmlLoader.getController(); mainController.setMainStage(primaryStage); primaryStage.setTitle("Адресная книга"); primaryStage.setMinHeight(315); primaryStage.setMinWidth(290); Scene scene = new Scene(fxmlMain, 315, 290); primaryStage.setScene(scene); primaryStage.show(); } public static void main(String[] args) { launch(args); } } Controller主類別： @Override public void initialize(URL location, ResourceBundle resources) { columnFIO.setCellValueFactory(new PropertyValueFactory ("fio")); columnPhone.setCellValueFactory(new PropertyValueFactory ("phone")); try { fxmlLoader.setLocation(getClass().getResource("../fxml/edit.fxml")); fxmlEdit = fxmlLoader.load(); editDialogController = fxmlLoader.getController(); } catch (IOException e) { e.printStackTrace(); } initListeners(); fillData(); }
