为什么java找不到twilio？

Question

我正在使用Eclipse和Gradle。Twilio被列为依赖项。所有版本都是最新的。引用Gradle的代码将无法编译，并返回Twilio类不存在的错误消息。在线代码令人沮丧地过时了。我希望这里有人能帮忙。

我正在运行的代码非常基本：

    package SendAndReceiveSms;
    
    import com.twilio.Twilio;
    import com.twilio.rest.api.v2010.account.Message;
    import com.twilio.type.PhoneNumber;
    
    public class SmsSender {
        public static final String ACCOUNT_SID = "**Redacted**";
        public static final String AUTH_TOKEN = "**Redacted**";
        
        public static void main(String[] args) {
            Twilio.init(ACCOUNT_SID, AUTH_TOKEN);
            Message message = Message.creator(
                    new PhoneNumber("**redacted**"),
                    new PhoneNumber("**redacted**"),
                    "Message testing.")
                    .create();
            System.out.println(message.getSid());
            //sendMessage("**redacted**");
            }
        
        public void sendMessage(String numToSend) {
            String n = numToSend;
            Message message = Message.creator(
                    new PhoneNumber(n),
                    new PhoneNumber("+**(redacted)**"),
                    "Message testing.")
                    .create();
            System.out.println(message.getSid());
            }
        
    }

    dependencies {
        // This dependency is exported to consumers, that is to say found on their compile classpath.
        api 'org.apache.commons:commons-math3:3.6.1'
    
        // This dependency is used internally, and not exposed to consumers on their own compile classpath.

        // Use JUnit test framework
        testImplementation 'junit:junit:4.12'
    }

我看你的项目设置没有任何问题。您可以将其与此参考项目进行比较。

因此，我怀疑您看到的问题与Eclipse如何导入Gradle项目有关。我不是一个普通的Eclipse用户，但我确实尝试过这个问题。当我在上面的报告中导入项目时，我看到了与您类似的导入错误。我首先告诉Eclipse这是一个Gradle项目（项目上下文菜单
