Follow these steps to achieve what you want:
- Open the preferences dialog (located in Windows -> Preferences on Windows/Linux or in the Eclipse menu on Mac).
- Go to Java > Code Style > Formatter in the tree on the left
- You see the active formatter profile. You can edit it using the "Edit ..." button. Click that.
- Go to the tab "Line Wrapping", select "Method Declarations" > "Parameters" on the lower left.
- On the bottom left you see the "Settings for parameters" group. Set the Line wrapping policy to "Wrap all elements, except first element if not necessary". Set the Indentation policy to "Indent on column".
- Close all dialogs by clicking ok.
You should now have the behavior you intended. If it fits your needs, you might want to apply the same settings for constructor parameters as well.
