Hi Patric,
In order to modify the build order of the projects in your workspace please follow these steps:
- Go to menu Window > Preferences

- Click on General > Workspace > Build Order

- Uncheck the option "Use default build order"
- Now you should be able to modify the build order of the projects, once you finish click on "Apply" then "OK"
Hope it helps!
