Unable to resolve the .classpath error

Hello Experts,

While I am creating the project from the Development Configuration Prospective I am getting ".classpath is read-only" error .Enclosed is the error screenshot for your reference.

classpath read-only error comes only for a particular DC. All other DCs are successfully downloaded.

I have deleted the DC from the Local work space and restarted NWDS. Still issue persist.

Any suggestions/experience/documentation with regard to this issue would be highly appreciated. please reply to rashmitap.86@gmail.com

Regards,

Rashmita
