Import local update site.
This action allows you to import the contents of a local Eclipse update site into the database. This way you can import one or more Eclipse update sites into a single, consolidated NSF-based update site. So if you have multiple eclipse update sites you do not need to create a database for each one.
You need all files to import
If you try to import with just the site.xml file the process will work but no plugins or features will be imported unless they are local and in the related directories below the site.xml files location on your system.
To import your site do the following.
1. Click "Import local update site" action button.
2. You will see the following dialog box.
In the dialog boxes "site.xml" field you should enter the full path to the site.xml file on your system.
3. Click OK when correct.
