NoClassDefFoundError means that the class was available while compiling but not able to find the definition at run time. NoClassDefFoundError表示该类在编译时可用，但在运行时找不到该定义。 Try by upgrading your httpclient depedency, 尝试升级您的httpclient权限，
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.5.3</version>
</dependency>
And then run clean install 然后运行clean install
