We use Git and Jenkins as our build&release system and each build is assigned a version number which looks like this:
6.0.12345. Here, the
12345 part is a counter which increments with each build. The counter is stored on the build server in a simple text file, which is rewritten every time a build occurs. It's worth noticing that this file is not under version control.
I was thinking about more elegant way to manage build numbers, which will allow for easier portability (say move build server to a new machine) and scalability (adding another build server would be very tricky with the current setup).
The only thing I can think of now is using commit hash instead of number, but this will make it difficult to say which of two builds came first, also, I don't think customers will be willing to accept such a change.
Any ideas are appreciated.
