How to flatten packages in eclipse?

问题:

I'm trying to create a flattened project hierarchy in eclipse 4.2 Juno - this is the latest version at time of writing.

I've enabled Package Presentation -> Flat in Package Explorer yet this has made no difference, the view is still hierarchical.

I cannot find any plugins which offer an improved package navigation experience. I simply desire the most productive configuration, i.e. a layout with no unnecessary clicking of expand/collapse arrows!

Any suggestions?

Turns out the 'Flat' option wasn't working because the project wasn't a Java project in eclipse's eyes.

I'd just checked out a Maven project from our SCM (svn). I noticed there was no 'J' on the project folder icon in Package Explorer. I then did Right-Click -> Configure -> Convert to Maven Project to fix.
