Copying Eclipse Preferences

If you want to transfer your preferences from one Eclipse installation to another, you can try the following approaches:

Option 1: Export/Import
Export your current preferences to a file and then import them into your new installation.
Go to File > Export and then choose to export General > Preferences to the local filesystem. Then start your second version of Eclipse, go to File > Import and choose to import General > Preferences.

Option 2: Copy runtime setting directory
Copy ${ECLIPSE_WORKSPACE}/.metadata/.plugins/org.eclipse.core.runtime/.settings from the existing installation to the new one.
