我从github下载了一个开源项目后，导入到自己Eclipse之后，遇到了这个烦人的错误消息：
The declared package "com.sap.smartService" does not match the expected package "main.java.com.sap.smartService"
这是我的项目文件目录：
解决方案：对项目点击右键，选择Properties->Build Path, 发现src文件夹被设为build path。
首先右键src文件夹，选择Remove from Build Path将其从build path中移除：
然后选择src/main下面的java文件夹，设置成build path，重启Eclipse：
错误即消失：
