getting permission denied on creating manifest.yml file

Hi,

I have created a got project. I pushed to github repository. Jenkins then get the  project from the github and build succesfully  and deployed in to cloudfoundry. I have configured  webhook in github. configured cloud foundry plugin in jenkins and github repository. jenkins built and deplyed successfully to cloud foundry.

The problem is  later I changed in my manifest.yml in my project and then commit yhe code . I pushed the modified file. Modified file is coming to gitgub repository. But while buliding happens  in jenkins  it is giving v=can not create manifest.yml , permission denied.

Can anybody tell me why it is giving permission denied  on later. Is there anything to configure on gitub or jenkins?
