After some trying, I found a way that works, at least for me.

As noted in the bug report, the latest version of Eclipse JET requires UML2 in a version strictly below 4.0.0. The Version that comes with Juno is 4.0.1., so Eclipse will refuse to install. Similarly, UML2 3.1.2 (the latest version available below 4.0.0) requires EMF in a version below 2.7, while Juno's version is 2.8, so this won't install either.

However, note that UML2, version 3.1.2, is also available in editions other than the update site. You can download the mdt-uml2-SDK-3.1.2.zip, unzip the archive, and simply merge the features and plugins folders into you Eclipse installation, thus circumventing Eclipse being picky about the version numbers.

Step by step:

  1. install Eclipse Juno, install other features (EMF, SVN, etc.), exit Eclipse
  2. (optionally, create a backup, in case something goes wrong)
  3. get mdt-uml2-SDK-3.1.2.zip, and merge its features and plugins into your Eclipse installation
  4. get the JET 1.1.1 Update Site, and install JET via Eclipse's install mechanisms

As far as I've tested, everything seems to work.
