You cannot run goals for multiple projects using m2e. I suggest the following:
- If projects are related, bundle them into a parent project and run the deploy goal on the parent project. You will need to tweak the goals that need to run as part of the deploy phase
- Use an assembly project that uses artifacts from these 3 projects and creates required assemblies and does the deployment
- Write a script (batch or shell) which executes goals for these projects one after the other. This can be run from eclipse as an external command
