version

Checksum's for each file are generated and are used to create a checksum that is used when publishing to maven central. In order to retry a failed publish without needing to change any functionality, we need a way to generate a different checksum for the source code. We can change the value of this property which will generate a different checksum for publishing and allow us to retry. The value of version doesn't need to be kept up-to-date with the version of the code.
