Mashape Unirest Java : java.lang.NoClassDefFoundEr

问题:

I'm building an application using Mashape's Unirest library(unirest-java-1.2.6.jar) . I'm getting NoClassDefFoundError during runtime. I tried CommonsWare's method. But it didn't work. Here is the screenshot of Java Build Path. Anything wrong in this screenshot??

I'm the author of Unirest-Java.

In order to use the library, you need to include the required dependencies into your project:

• Apache HttpComponents Client
• Apache HttpComponents AsyncClient
• Apache HttpComponents Mime
• JSON library

Using Maven is the preferred method: https://github.com/Mashape/unirest-java#installing

Otherwise the libraries can be manually downloaded from http://hc.apache.org/downloads.cgi and http://www.json.org/java/index.html

But again, I would strongly recommend to use Maven. Also please update the Unirest library to the newest version because 1.2.6 is deprecated now.

It's advisable to package everything in one uber jar by using Maven.

Please refer to this post on how to use Unirest in your Java projects.
