1、Download 'Binary' package of the latest official release from the project download page.
There should be 7 jars in total (components marked with (*) include additional features and are optional) on the classpath.
- commons-logging-x.x.x.jar
- commons-codec-x.x.x.jar
- httpcore-x.x.x.jar
- httpclient-x.x.x.jar
- httpmime-x.x.x.jar (*)
- httpclient-cache-x.x.x.jar (*)
- fluent-hc-x.x.x.jar (*)
2、把这几个.jar文件放到 Javajdk1.7.0_17jrelibext目录下面，不同的安装版本可能有差异。
3、引用，右键点击工程名->bulid paths->add external Archives->选择刚才添加的.jar文件即可。
