I can not exactly answer why your question is off topic. How ever I can answer you what contributes your question get closed. As per the fundamental rule of SE is "Questions that are not a good fit for this site may be voted closed by experienced community members.". Now the question is what makes your question not a good fit for the site
Your question is very vague and too open. You described issue and asking help. Not asking specific question. SE is Question and answer site where you post constructive questions and invite answers for those question. Here what is your specific question? "can any body help" is not constructive question.
Your question is not showing any research effort. For any question that you want help from the community, first do your research and document that research.
Above are the basic things that makes your question not fit into SE. First you fix the above things in your question. Try to do research or Google why that error is coming and how can you fix that. Try to trouble shoot based on your research. If you have still problem then modify your question by specifying what ever research that you have done and ask the specific question. The question would be like the below
I am trying to build application A on platform P as per the specified build process. How ever I am getting the below exception.
I have done following things to trouble shoot and get rid of that exception.
Explain the research that you have done and trouble shoot that you did
No my specific question is, why this error occurring and how to over come this error in order to build application successfully
The above pattern will make your question better than now.
And you modify your question then you can request members who voted for close. Then there are chances that your question gets reopened. Or if they see any other problems with your question they will let you know.
