FAQ How do I find out what plug-ins have been installed?
One way of finding out is to select Help > About Eclipse Platform >. From this dialog, click Plug-in Details to get a list of all installed plug-ins, along with vendor and version information. If you instead click Configuration Details, you will be rewarded with a full credit report of your current Eclipse installation. The main sections contain information about your system properties, what features and plug-ins have been installed, preferences specified by you, the Update Manager log, and a dump of the error log, which lists problems that have been reported by various plug-ins.
