- click on your model (on the Model Explorer view),
- in the Properties view, choose the Profile tab,
- click on Apply registered profile,
- into the opened pop-up, choose Java

- on Properties View, Profile tab, click on Apply stereotypes,
- on the opened pop-up choose JavaSrcFolder, and add it into Applied Stereotypes, and close the pop-up by clicking on Ok button.
- you now can change the project name into the JavaSrcFolder stereotype
From Eclipse Preferences

- Open Eclipse preferences,
- Search for Papyrus section,
- Choose Java Classes Generation sub-section,
- Change default source folder name value
