You may sometimes want to disable, uninstall or remove some of the features and plugins in Eclipse.
Removing the plugins that you manually installed on top of the Eclipse installation is easy:
Go to Help -> Installation Details. Click the tab Installed Software.
Choose any of the features or plugins here and click on Uninstall at the bottom-right of this dialog to remove it.
Removing the features and plugins that shipped with Eclipse is more tricky, since it cannot be done from the UI. Here is how:
Go to Help -> Installation Details. Click the Features and Plug-ins tabs to find out what you want to remove.
Every feature or plugin has a Feature ID, shown in a column of the same name. This is just the name of its JAR file.
Close Eclipse. Go to the directory where Eclipse is installed. To remove a Feature, go to the
features directory, else for Plugin go to the
plugins directory. Delete the directory or JAR file with the Feature ID you identified in earlier step. Restart Eclipse.
