“找不到文件"运行新的 LibGDX 项目时 [英] "File not found" when running new LibGDX project

问题描述

我尝试学习 LibGDX，我安装了列出的所有软件 这里在新格式化的 mac OS X Maverick 上使用新的 Eclipse 4.3.

I trying to learn LibGDX, I install all the software listed here with a new Eclipse 4.3 on a fresh formatted mac OS X Maverick.

一切顺利，重新启动后，我下载并执行 gdx-setup.jar，填写表格，然后导入 Eclipse.

Everything goes smooth, after a reboot, I download, and execute the gdx-setup.jar, fill the form, and import into Eclipse.

当我尝试运行桌面时，没有错误，没有警告.(右键桌面项目，Run As -> Java Application).

No error, no warning, when I try to run the desktop. (Right click the desktop project, Run As -> Java Application).

我收到了这个错误

我在这里发现了很多类似的问题，我都尝试了，但没有任何好的结果...昨晚我发现了 这个，很酷，我有最新的 Java 1.8，一个 mac，和 Eclipse 完美契合...

I found a lot of similar issue here, I try them all without any good result... Last night I found this, very cool I have the latest Java 1.8, a mac, and Eclipse fit perfectly...

但没有成功，我尝试使用 Java 1.6 和 1.7，总是同样的错误(未找到文件，我保留 Java 1.7)

But no success, I try with Java 1.6 and 1.7, Always the same error (No file found, I kept Java 1.7)

我开始做一些debug，这里我只修改导入生成的原始代码.

I begin to do some debug, here my only modification of the original code generated by the importation.

package com.diesel.bugs;

import com.badlogic.gdx.ApplicationAdapter;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.graphics.GL20;
import com.badlogic.gdx.graphics.Texture;
import com.badlogic.gdx.graphics.g2d.SpriteBatch;

public class DieselBugs extends ApplicationAdapter {
    SpriteBatch batch;
    Texture imgExternal,imgLocal;

    @Override
    public void create () {
        batch = new SpriteBatch();
        String pathLocal = Gdx.files.getLocalStoragePath();
        String pathExternal = Gdx.files.getExternalStoragePath();
        Boolean isExternal = Gdx.files.isExternalStorageAvailable();
        Boolean isLocal = Gdx.files.isLocalStorageAvailable();
        imgExternal = new Texture(Gdx.files.external("/Desktop/badlogic.jpg"));
        imgLocal = new Texture(Gdx.files.local("badlogic.jpg")); 
    }

    @Override
    public void render () {
        Gdx.gl.glClearColor(1, 0, 0, 1);
        Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
        batch.begin();
        batch.draw(imgExternal, 0, 0);
        batch.end();
    }
}

奇怪的是 pathLocal 等于 "".Gdx.files.getLocalStoragePath() 什么都不返回(空字符串)正常吗?

The weird thing is pathLocal is equal to "". Is it normal for Gdx.files.getLocalStoragePath() to return nothing (empty string)?

还有

imgExternal = new Texture(Gdx.files.external("/Desktop/badlogic.jpg"));

效果很好.只有本地的会报错，isLocal也是，isExternal返回true.

Works great. only the local one gives the error, also isLocal, and isExternal return true.

我尝试了很多组合，例如 /assets/data/badlogic.jpg、/assets/badlogic.jpg、/data/badlogic.jpg、data/badlogic.jpg 和 badlogic.jpg.

And I try a lots of combinations, like /assets/data/badlogic.jpg, /assets/badlogic.jpg, /data/badlogic.jpg, data/badlogic.jpg, and badlogic.jpg.

图片 badlogic.jpg 在那里，我把它放在多个地方确定.

The image badlogic.jpg is there and I put it in multiple places to be sure.

现在我在这里寻求帮助的原因是我只是在 PC 上尝试所有相同的步骤，一切都很好.

And now the reason why I'm here for help is I just try all the same step on a PC and everything works great.

我的新 Mac 及其设置有什么问题?

What is wrong with my new mac and it's setting?

当您运行桌面项目时

应用程序将在第一次失败.打开刚刚创建的运行配置，将工作目录设置为android/assets/目录！

The application will fail the first time. Open the Run Configuration you just created and set the working directory to the android/assets/ directory!

将您的桌面项目链接到 android assets 文件夹?

link your desktop project to android assets folder?

转到 Run => Run Configurations.. => 选择 DesktopLauncher，Arguments Tab => Working Directory => Others 然后浏览到yourproject-android/assets/并点击 Apply => Run

Go to Run => Run Configurations.. => choose DesktopLauncher, Arguments Tab => Working Directory => Others then browse to yourproject-android/assets/ and click Apply => Run
