I started getting the following error in RAD 9.1.1(websphere 8.5) since yesterday. Also this error is coming on only one project in my workspace. I do have about 7-8 projects which are clean- no errors. Any help or input on this is appreciated..
The project was not built due to "Internal error - the selected file is a system file that cannot be modified. It will be hidden.". Fix the problem, then try refreshing this project and building it since it may be inconsistent
Issue resolved, goto Target, compiled classes folder of that project and DELETE copyarea.db and refresh your project. The error is because the RAD copies the read only files ".copyarea.db" to the classes folders and during cleanup, RAD fails to delete these files.
