404 error when accessing Cucumber Reports

I hit this “404 error when accessing Cucumber Reports” error because my jar was not downloaded by maven , someone change my pom setting , if you meet this error  you should check whether the program has download the cucumber test jars and confirm whether the test cases has run. Because maven ban the snapshot version , so maven could not download the jar and perform the tests , with no testcases and no pom xml file , there is not json result file generated  by cucumber . If you meet this error , pls confirm your maven and jar work fine.
