java - 导入附加库后 Android Studio gradle 错误 - smack

Question

我有一个奇怪的错误，我找不到答案。

在我的类上做了一些导入之后(下面的代码)

    package info.zajacmp3.servercommunication;

import org.jivesoftware.smack.Connection;
import org.jivesoftware.smack.ConnectionConfiguration;
import org.jivesoftware.smack.XMPPConnection;
import org.jivesoftware.smack.XMPPException;

/**
 * Created by Mateusz on 04.06.13.
 */
public class ServerCommunication {



    public static boolean isSendableOverInternet(){
        return false;
    }
}

我得到了 gradle 错误:

Gradle: 
FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':PPMMessenger:compileDebug'.
> Compilation failed; see the compiler error output for details.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

当我运行堆栈跟踪时，它什么也没告诉我...因为没有跟踪到我的代码。

这是堆栈跟踪:

* Try:
Run gradlew tasks to get a list of available tasks.

* Exception is:
org.gradle.execution.TaskSelectionException: Task 'compileDebug' not found in ro
ot project 'Mateusz'.

感谢任何帮助。我在这里看不到任何可以帮助我自己解决这个问题的东西。

刚遇到这个问题，我需要将自定义 jar 库添加到 build.gradle 文件中:

dependencies {
    compile files('libs/android-support-v4.jar')
    ADD FILE HERE   
}
