顯示java.lang.NullPointerException:需要位置。
當我使用gradle與javafx插件組裝後運行程序時。如果我從IntelliJ Idea運行它,一切都可以。 Java源文件和.fxml位於某個包中。
的build.gradle
apply plugin: 'java'
apply plugin: 'application'
apply plugin: 'idea'
apply from: 'javafx.plugin'
javafx {
javaRuntime = 'C:\\Program Files\\Java\\jdk1.7.0_45'
appID 'FXMLExample'
appName 'fxml example application'
mainClass 'local.hz.FXMLExample'
}
task "create-dirs" {
sourceSets*.java.srcDirs*.each {it.mkdirs()}
sourceSets*.resources.srcDirs*.each {it.mkdirs()}
}

FXMLExample.java

public class FXMLExample extends Application {
@Override
public void start(Stage stage) throws Exception {
Parent root = FXMLLoader.load(getClass().getResource("fxml_example.fxml"));
Scene scene = new Scene(root,300,275);
stage.setTitle("FXML WELCOME!!");
stage.setScene(scene);
stage.show();
}
public static void main(String[] arguments) {
launch(arguments);

沒有幫助 –
這是相同的路徑。 –
