我尝试按照 Twilio 教程通过 Java 代码发送短信 此处 但我在 收到 java.lang.NoClassDefFoundError: com/fasterxml/jackson/databind/JsonMappingException第 13 行 在我的代码中，我正在编写 Service service = Service.creator("My First Messaging Service").create();

I am try to send a text message via a Java Code following Twilio tutorial here but i am getting java.lang.NoClassDefFoundError: com/fasterxml/jackson/databind/JsonMappingException at Line 13 in my code where i am writing Service service = Service.creator("My First Messaging Service").create();

我尝试关注此线程并添加了所有必需的依赖项，但我不知道在代码中的何处使用 @JsonIgnore引起:java.lang.NoClassDefFoundError: com/fasterxml/jackson/databind/JsonMappingException$Reference

I tried following this thread and have added all the required dependencies but i don't know where to use @JsonIgnore in my code Caused by: java.lang.NoClassDefFoundError: com/fasterxml/jackson/databind/JsonMappingException$Reference

推荐答案

对于任何来到这里寻找解决方案的人来说，这都是一个严重的依赖问题.我在我的项目中手动添加了 3 个 jackson API(注释、数据绑定和核心)，这就是问题所在.它实际上需要更多.

To anyone who came here looking for a solution, it is seriously a dependency problem. I had 3 jackson APIs' (annotations, databind and core) added manually to my project and that was the issue. It actually required more then that.

所以我所做的是通过遵循 Convert Existing Eclipse Project 切换到 Maven 项目到 Maven 项目 和 pom.xml，在 <builds> 中，我复制粘贴了 twilio 从这里开始工作所需的所有 <plugins>href="https://github.com/twilio/twilio-java/blob/main/pom.xml" rel="nofollow noreferrer">https://github.com/twilio/twilio-java/blob/main/pom.xml

So what i did is switched to Maven project by following Convert Existing Eclipse Project to Maven Project and in pom.xml, in <builds> i copy pasted all the <plugins> that twilio required to work from here https://github.com/twilio/twilio-java/blob/main/pom.xml

感谢@MichałZiober 的建议，它最终奏效了.

Thanks to @MichałZiober for the suggestion, it eventually worked.
