See which plugins are installed by eclipse

To see which plugins are installed, click Help > About Eclipse Platform, and in the dialog box that appears, click Plug-in Details and configuration details to see which plugins are installed. The version number of each plug-in, the provider, and the installation log information. But there is a better way to look at it with manage configuration.
1. Open Update Manager and click Help > Software Updates > Manage configuration, which opens the Product Configuration dialog box.
2. In the Product Configuration dialog box, click on the root node of the left window to find a list of installed plug-ins, select the plugin, click on the Show properties item in the right window to get further information.
3. Click Show Install locations on the toolbar to display the installation directory for each plugin.
4. Click Show Nested features on the toolbar to display the sub-plugins that make up each plugin.
5. Click Show Disabled features on the toolbar to display unused plugins.
6. Click installation History on the toolbar to display the installation log in HTML format.
