Question

我最近更新了我的kotlin和kotlin扩展插件，并在构建时遇到以下错误。我尝试使用gradle清理构建或同步项目，但没有任何工作

有人可以指出这有什么问题吗？

Answer 1

我通过在终端中构建项目然后在intellij（或android studio）中运行app来解决了这个问题。

gradle clean build - ＆gt;在ide中运行app

Answer 2

对我来说，解决方案是在Android Studio中打开Gradle Console窗口并使用StackTrace运行构建。

然后，通过阅读，我意识到在Kotlin做一些事情的新事物需要我的代码改变，但正常的Gradle构建并没有抓住这些问题。

将视图投射到TextView或其他任何情况下，这些都不再相关，并且必须更改为findVieById格式。 e.g：

val textView = snackbarView.findViewById(R.id.snackbar_text) as TextView

必须改为

val textView = snackbarView.findViewById<TextView>(R.id.snackbar_text)

Answer 3

对于我最近正在从事的项目，我遇到的是相同类型的错误，该错误是由于调用不再存在的静态方法引起的。

MessageService.java

public class MessageService extends FirebaseMessagingService {

    /*
    This method was commented out

    private static String GetReviewTopic(String userId) 
    {
        return "/topics/"+userId+"/review";
    }
    */
}

AppActivity.java

@Override
public void onCreate() {

    ...

    /* 
    No complication error was caused despite the
    method not being defined. 
    */                        
    MessageService.GetReviewTopic(currentUser);

    ...
}

不幸的是，Android Studio并未针对丢失的静态方法报告“语法错误”，也没有任何有意义的复杂错误可以帮助我追踪问题。

希望这个答案能够节省一些人的故障排除时间！
