为什么java找不到twilio？

如何解决为什么java找不到twilio？

我在 Gradle 中使用 Eclipse。 Twilio 被列为依赖项。所有版本都是最新的。引用 Gradle 的代码不会编译并返回 Twilio 类不存在的错误消息。在线代码令人沮丧地过时了。我希望这里有人可以提供帮助。

我运行的代码非常基础：

    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.
        implementation 'com.google.guava:guava:28.2-jre'
        
        //compile group: "com.twilio.sdk",name: "twilio",version: "7.45.+"
        //compile group: "com.sparkjava",name: "spark-core",version: "2.7.1"

       // implementation 'com.twilio.sdk',version: '8.11.0'
        //runtimeOnly group: 'com.twilio.sdk',version: '8.11.0'
        // Use JUnit test framework
        testImplementation 'junit:junit:4.12'
    }

解决方法

我认为您的项目设置没有任何问题。您可以将其与 this reference project 进行比较。

所以，我怀疑您看到的问题与 Eclipse 导入 Gradle 项目的方式有关。我不是一个普通的 Eclipse 用户，但我确实为这个问题尝试过。当我在上面的 repo 中导入项目时，我看到了与您类似的导入错误。我能够通过首先告诉 Eclipse 这是一个 Gradle 项目（项目上下文菜单 > 配置 > 添加 Gradle Nature）然后刷新来修复它们项目（项目上下文菜单 > Gradle > 刷新Gradle 项目）。我从 this answer 那里得到了这些步骤。然后一切正常。
