To resolve the dependencies of this OSGi or Eclipse Plug-in project you need the Eclipse Plug-in Development Environment (PDE) tooling (which is obviously missing in your IDE):

1. Help > Install New Software
2. In Work with select --All Available Sites--
3. Select Eclipse Plugin Development Tools
4. Click Finish

Similar to Maven dependencies are specified by IDs/names with version ranges in a specific file (Maven: pom.xml; OSGi bundle / Eclipse plug-in: META-INF/MANIFEST.MF). Make sure all required plug-ins are in your target platform: Window > Preferences: Plug-in Development > Target Platform.
