Docker image building doesn't work out of the box when using project template

There's a problem in building docker image when using project template:

• lein-scm-source creates scm-source.json in target dir. In project.clj target-path is set to target/%s so the location of the file is something like target/base+system+user+dev/scm-source.json
• Dockerfile expects scm-source.json to be in the root of the project

I guess the obvious fix is to change lein-scm-source to generate in project root instead, or make it configurable and preconfigure it in the template. I am happy to provide a PR if you think this is the correct fix.

This is more a ticket for lein-scm-source I think (so it can generate .scm in current dir). Alternatively Dockerfile can be generated on demand but It looks like unnecessarily complex solution.

Another way to fix this (suggested by @dryewo): modify template project.clj to include alias scm-source for lein with-profile uberjar scm-source. Then the file would be generated in target/uberjar and we can change the path in Dockerfile to target/uberjar/scm-source.json.
