How to configure Eclipse formatter to not insert blank line between field declarations?

The Eclipse i am using is:

Eclipse Java EE IDE for Web Developers.
Version: Indigo Service Release 2
Build id: 20120216-1857

As the picture above shows, there is a 'Between import groups' under the Blank Lines tab and it works for me. You can check it out.

Strange, I cannot reproduce that behavior with my own formatter profile (eclipse3.5.1).

There was a setting back in 2003 (bug 38523) to "Insert new line after each parameter if line is too long", but this has been integrated into the "Line Wrapping" panel a long time ago.

Are you sure the newlines are not added because of a wrapping issue (due to a maximum line length too short)?

The tab "Blank Lines" does have an "Existing blank lines" section, with a "Number of empty lines to preserve" field which can be set to 1, and should address the later part of your requirements.
In that same tab "Blank Lines", check also the value of the "Before field declarations": "1" could explain the blank lines you see.

The formatter options are in the org.eclipse.jdt.ui.prefs file, which is:

• either in your workspace (.metadata.plugins\org.eclipse.core.runtime.settings)
• or in the .settings of your project.

You can try and empty that file to check if the problem remains. It that clear up the issue, try adding some lines into that file, up to the point where the problem comes back.
