During installation of HibernateSynch plugin on Eclipse Luna from http://hibernatesynch.sourceforge.net/ I getting a “Failed to prepare partial IU” error.

I could solve this error by installing “Eclipse 2.0 Style Plugin Support” from “Eclipse Tests, Examples, and Extras” of “The Eclipse Project Updates – http://download.eclipse.org/eclipse/updates/4.4”.

So go to Help -> Install New Software…, then choose “The Eclipse Project Updates – http://download.eclipse.org/eclipse/updates/4.4” from the “Work with” list and then in the “Eclipse Tests, Examples, and Extras” category check “Eclipse 2.0 Style Plugin Support” and install it. After restarting Eclipse, install HibernateSynch again and this time the installation will succeed.
