IDE Setup
Since this is an Xtext project you need an Eclipse IDE to work on it. Download the Eclipse IDE for Java and DSL Developers from here. The latest version of eclipse we worked with is 2018-09.
Before importing the project you need to install the Tycho Configurator m2e connector. This can be done by following these steps:
- Start your Eclipse
- Open the maven preferences page: Window -> Preferences -> Maven
- Under Discovery press the button Open Catalog and search for Tycho. You should find the Tycho Configurator:
- Select the Configurator and press Finish.
- An eclipse installation wizard will appear. Go through the wizard to finish the installation and restart eclipse.
After having installed the Tycho Configurator you can import the project with as an existing maven project:
Choose the directory in which you cloned the project as root directory and select all projects:
After importing the project you will have lots of build errors. This is because you have to generate some Xtext sources first. There exists an eclipse launch configuration called 'GenerateContextMappingDSLInfrastructure' delivered with the project:
Run this launch configuration (yes, even if there exist build errors). As soon this has completed, execute a clean build with Project -> Clean... -> Clean all projects.
That's it. You should have a clean workspace now without build errors.
