maven project: SWT 3.5 dependency: any official public repo?

Well, in short, I may need to grab new SWT version instead of 3.3 we're using for now. The project now has only this dependency and builds fine:

<dependency>
  <groupId>org.eclipse.swt.win32.win32</groupId>
  <artifactId>x86</artifactId>
  <version>3.3.0-v3346</version>
</dependency>

AFAICGoogle, there is no more recent version in the public maven repo: http://repo1.maven.org/maven2/org/eclipse/swt/

So:

1. Is there some public maven repo with recent builds?
2. If not, where do you get the jars you install locally and/or in your corporate Nexus?
3. Any groupId/artifactId suggestions/conventions you know of?

TIA

PS: I am mostly a noob as to Eclipse products site layout and usually get lost in Google search results and/or the Eclipse site itself... so while the answer may be obvious for you it would likely not be so for me, even retrospectively.
