9. Beginning of the screenshot
slides,
which where shown live in
Eclipse

11. We recommend to leave it like in the sreenshot,
because all settings made here are only locally in your Eclipse IDE
and therefore won't be available for others who checkout the Projects
Tip : Rather specify
your settings
in the Gradle build files

12. Gradle automatically chooses
the right version, which is defined
in the build files or
the latest, if no version is defined.
The preview also shows the
project structure of
the overall import

13. Gradle Task View
Shows the tasks of the Gradle projects
Filter options in the
View's menu

14. Gradle Execution View
See all running tasks with options to open test files, see failures and (re-)run tests

15. Jump to test file and see test
summary

16. Gradle Run Configuration

17. The New Wizard uses the
gradle init --type 'java-library'
command to create this Project
