Here is the solution:  
Inside your work space (For me it is D:\m\Automation Project\Tests), Create a folder named "target" containing two subfolders "allure-results" and "allure-reports".  
2. In Post Build Actions of Jenkins Project provide these entries.  
Results: target/allure-results  
Report Path: target/allure-reports

Now run your tests and allure reports will be generated without any issues.

就是说必须要在项目下建target目录，target目录下建allure-results和allure-reports文件夹，名字也必须是这个，然后在jenkins中配置这两个目录。
