Question

我正在搜索将Android设备变成FTP服务器的库。 Java FTP客户端似乎有无数的库，但是我看到了一个问题here.

所以我在这里遵循这个教程：

然而，运行我的应用程序会给我一个NoClassDefFoundError

MainActivity.java

<ul>
    @foreach($users as $user)
        <li>
            <span>{{$user->count}}:</span>

            @foreach($user->names as $index=>$name)
                <span><a href="#">{{$name}}</a> @if($index!=count($user->names)-1) ,@endif </span>
            @endforeach
        </li>
    @endforeach
</ul>

的build.gradle

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        FtpServerFactory serverFactory = new FtpServerFactory();
        FtpServer server = serverFactory.createServer();
        // start the server
        try {
            server.start();
        } catch (FtpException e) {
            e.printStackTrace();
        }
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
}

logcat的：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    defaultConfig {
        applicationId "com.ken.androidftpserver"
        minSdkVersion 15
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    packagingOptions {
        exclude 'META-INF/DEPENDENCIES.txt'
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/notice.txt'
        exclude 'META-INF/license.txt'
        exclude 'META-INF/dependencies.txt'
        exclude 'META-INF/LGPL2.1'
    }
}

那里有libs吗？

问题是我使用的是不同版本的slf4j-simple和slf4j。他们需要是一样的。
