We have just merged a large project into our main development branch.
Our source repository, on Bitbucket, has the files that we merged

However, our build plan on Bamboo doesn't seem to include these files.
This is the first time we have included changes on our web project. Our other projects, being normal console applications, have new files all the time and they are always built.
I have checked the package that is built, and the files are indeed not there

Is there a way to include these changes in our build? As sated, they do exist on the repository but not on the build. They are there, just not on the finished product.
