使用Javafx Maven插件編譯項目後，程序無法找到資源

2015-11-12 90 views

好吧，即時通訊對於javafx和一般編程來說相當新穎。我從來沒有真正打包過一個程序，因爲我從來沒有需要在IDE之外運行它們。我需要打包我的javafx程序，並且必須使用maven來處理所有其他依賴關係。使用Javafx Maven插件編譯項目後，程序無法找到資源

在包含pom文件的目錄中使用命令mvn jfx：jar編譯程序後，構建成功並生成我的jar。當通過WINRar檢查時，它包含以前在根目錄的my/src/main/resource文件夾中的所有文件。

但是，當使用java -jar（nameofjar）.jar運行時，它不會啓動，而是會產生幾個錯誤，這些錯誤都與無法找到特定資源有關，特別是FXML以及其他資源。

Refrences到文件

welcome.fxml

public void start(Stage primaryStage) { 


    try { 
     AnchorPane pane = FXMLLoader.load(MainApp.class.getResource("welcome.fxml")); 
     Scene scene = new Scene(pane); 
     primaryStage.setScene(scene); 
     primaryStage.setTitle("HeelBot Beta "+versionNumber); 

     primaryStage.getIcons().add(new Image("Icon.png")); 
     primaryStage.setResizable(true); 
     primaryStage.show(); 
    } catch (Exception ex) { 
     Logger.getLogger(MainApp.class.getName()).log(Level.SEVERE, null, ex); 
    }

defaultProperties.properties

public class PropertiesManager { 
    public static void editProperty(String key, String value) throws IOException { 
     // create and load default properties 
     Properties defaultProps = new Properties(); 
     FileInputStream in = new FileInputStream("src/main/resources/defaultProperties.properties"); 
     defaultProps.load(in); 
     in.close(); 

// create application properties with default 
     Properties applicationProps = new Properties(defaultProps); 

// now load properties 
// from last invocation 
     in = new FileInputStream("src/main/resources/appProperties.properties"); 
     applicationProps.load(in); 
     in.close(); 
//set properties 
     applicationProps.setProperty(key,value); 
     FileOutputStream out = new FileOutputStream("src/main/resources/appProperties.properties"); 
     applicationProps.store(out, "---No Comment---"); 
     out.close(); 

    }

這將導致它找到FXML文件，但仍然拋出一個錯誤的屬性文件，我將不得不手動添加屬性文件放到項目目錄中。我如何讓打包的jar能夠找到自己的資源，而不是尋找jar之外的資源？

我是JavaFX的Maven的插件的維護者，偶然發現了每次事故這個問題;）

的問題是你讀取文件的「邏輯」中，訪問到內的財產，你的文件JAR以另一種方式完成，但這不是所使用插件的錯誤，這是一個普通的java事物（正如我們所拋出的exxception所指出的那樣）。要知道「當前文件夾」中，只是打印出來new File(".")

只是通知你關於JavaFX的Maven的插件配置：有什麼不對

這裏有一些鏈接，我發現你展示簡單的加載裏面的JAR文件的屬性：

Load properties file in JAR?

Load Properties from resources folder within JAR

編輯：請確保關於有關於「當前窩有點知識國王文件夾「，呼籲java -jar somejar.jar不同於java -jar somefolder/somejar.jar，造成很大的差異
