How to deploy an Eclipse project referencing a sub-project on Heroku?

Question

I'm working on a Java web project using Heroku as hosting PaaS. As IDE I'm using Eclipse and I'm trying to deploy this project.

In a previous version the project had only Maven dependencies, but now I'm referencing another project as dependency of the main web-app that doesn't reside in the main repository.

Which is the right approach to this case? Should I use a single repository?

Answer 1

The "right" way to do it is making the project you depend on a published artifact in a Maven repository. But that is a pain for small projects.

Here are some other options:

• Build the app locally from your /.m2/repository artifacts and deploy with Heroku Maven plugin
• Check the JAR file dependency in to Git as an unmanaged dependency
• Make the dependency a Maven module in your main project, but also make the module dir a Git submodule . That way it's still a separate project but can be deploy to Heroku as a single app .

If you decide to do it the "right" way, I recommend deploying the artifact to bintray.com , which is a little easier to use in this kind of scenario than, say, Sonatype.
