Development Guidelines

Building

This project is set up as a maven project, so use maven to build the project.
If you are working with IDE's like eclipse or IntelliJ use the corresponding mavenplugins.
Never check in the IDE specific files

Maven

Depenendcies

Add all dependencies to the dependencyManagement in the main pom.xml
Use a property for version control of the dependency
Never add submodules to the dependency management
Never add dependencies directly to the main pom.xml

New Modules

If you have to add a new module choose the correct parent
If the groupId will not change, do not define it. Maven will set it automatically from the parent.
Do not define a version tag. Maven will set it automatically from the parent.

Testing

Unit Tests

Create always jUnit tests if possible.
Avoid "Integrative" tests with dependency on external services
Testdriven development will be the correct way

Integration Test

If you have to make an integration test use the corresponding integration test project!
