In Eclipse (3.6):
- Install Checkstyle plug-in
- Import stylesheet using Windows –> Preferences, General –> Checkstyle –> New. Since you have an external file, choose “external file” as the type.
Right-click on your project in the Package view and select Checkstyle –> Create Formatter-Profile.
Then enable the formatter for your workspace: Windows –> Preferences –> Java –> Code Style –> Formatter. Select formatter: “eclipse-cs [project name]”.
Click OK!
