使用maven時無法讀取影像

2021-12-07 02:07:26 .NET開發

我目前正在為我正在制作的游戲進行單元測驗，并且在使用 maven 時遇到了一個我無法弄清楚的奇怪錯誤。

我已經跑了mvn clean，現在我的測驗失敗了。

這是我運行時遇到的錯誤mvn test -X：

這是我收到錯誤的代碼：

package G20;

import java.io.IOException;
/**

 */
public class Player extends AnimateEntity{
    
    /**
     * Constructor calls super constructor, sets sprites
     * @param x_pos
     * @param y_pos
     * @param sprites
     */
    public Player(int x_pos, int y_pos){
        super(x_pos, y_pos);
        //populating the sprite array list
        sprites = new ArrayList<BufferedImage>();
        try{
            sprites.add(ImageIO.read(getClass().getResourceAsStream("Sprites/player_1.png")));
            } catch(IOException e){
                e.printStackTrace();
            }
        try{
            sprites.add(ImageIO.read(getClass().getResourceAsStream("Sprites/player_2.png")));
            } catch(IOException e){
                e.printStackTrace();
            }
        setSprite(sprites.get(0));
        speed = 4;
    }
}

我很確定它與 maven 檔案有關，但我不確定它是什么。也許與我正在使用的影像閱讀庫有關？任何幫助將不勝感激。

uj5u.com熱心網友回復：

您遇到的問題是您的測驗無法實體化 Player（測驗類的第 24 行）。嘗試時將無法找到精靈資源，并且如果它的基類 AnimateEntity 正在執行其他作業，則可能會出現其他故障。

理想情況下，您應該在測驗用例中使用 Mock 物件。這樣它們就不會依賴于可能可用也可能不可用的資源。

如果您絕對需要資源來執行您的測驗，您需要配置 maven 將它們復制到目標檔案夾，以便您的測驗可以訪問它們。

此鏈接提供有關如何設定專案以使用目標目錄中的資源的資訊。

從 JUnit 測驗用例中找不到資源檔案
