问题描述

一直在尝试使用 Libgdx 框架，但遇到了一些令人沮丧的问题.我正在学习教程，但无法运行我的项目.我做错了什么?

Been trying to work with the Libgdx framework and have been experiencing some frustrating issues.. I'm following a tutorial and I'm unable to run my project. What am I doing wrong?

package com.mygdx.game.android;

import com.badlogic.gdx.ApplicationListener;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.graphics.Texture;
import com.badlogic.gdx.graphics.g2d.SpriteBatch;

public class AndroidLauncher implements ApplicationListener {

    SpriteBatch batch;
    Texture mario;


    @Override
    public void create() {
        batch = new SpriteBatch();

        mario = new Texture(Gdx.files.internal("mario.png"));
    }

    @Override
    public void resize(int width, int height) {
        // TODO Auto-generated method stub

    }

    @Override
    public void render() {
        Gdx.gl.glClearColor(1,1,1,1);


        batch.begin();
        batch.draw(mario, 50, 50);
        batch.end();



    }

    @Override
    public void pause() {
        // TODO Auto-generated method stub

    }

    @Override
    public void resume() {
        // TODO Auto-generated method stub

    }

    @Override
    public void dispose() {
        // TODO Auto-generated method stub

    }

}

这是我运行项目时控制台显示的内容:

Here's what the console displays when I run the project:

Exception in thread "main" java.lang.NoClassDefFoundError: com/badlogic/gdx/jnigen/NativeCodeGenerator
    at com.badlogic.gdx.utils.GdxBuild.main(GdxBuild.java:34)

推荐答案

我遇到了同样的问题，但意识到我正在运行 GdxBuild.确保您右键单击 DesktopLauncher.java > Run As > Java Application.

I had the same problem, but realised that I was running GdxBuild instead. Ensure that you right click on DesktopLauncher.java > Run As > Java Application.
