Me and 2 of my friends been working on a small app. The source code of the app is on a private repository on BitBucket but now we would like to make the code of our app public under the terms of GPL.
The problem is, when we started the application, we did not put in the classes or anywhere for that mater the copyright as stated in the GNU manual on how to apply the terms to your new programs
My question is: Can we annotate the classes now and make a commit with them and the app is under gpl license.(even if our previous commits did not include any of the copyright text. Or we should make a new repository and upload the software with the updated gnu license text.
We would prefer the first method if possible, but if it is a must we can make a new repository.
