You can configure the plug-in to save the contents of your Multi Clipboard to a file when Eclipse is closed. Contents are then reloaded when Eclipse is opened. You can even configure the plug-in to enable editing the contents of the Multi Clipboard.
Multi-Clipboard is distributed under the Eclipse Public License, v 1.0. You can find the license details online at http://www.eclipse.org/legal/epl-v10.html.
The license is an Open Source license. The source can be found here as a zip-file for download.
I hope the plug-in serves you well. In case you find any problems with using it, have ideas for additional useful features or any other comments, contact me.
If you like the plug-in or you have comments to make: let others know! Multi-Clipboard is listed on eclipse-plugins.info and on eclipseplugincentral.com. Both sites allow commenting and rating plug-ins. On eclipse-plugins.info, you need to be a registered user to rate plugins - register and rate Multi-Clipboard!. On eclipseplugincentral.com, you can rate the plugin anonymously - go here.
Release 2.1.1This is a patch because 2.1.0 was compiled under Java 5 leading to problems with users using JRE 1.4. No functional differences compared to 2.1.0 - Sorry for the trouble!
Click here for help on how to install the feature in Eclipse (for Eclipse-fluent users: you need an update-site with URL http://www.bastian-bergerhoff.com/eclipse/features, everything else is standard).
Alternatively, you may directly download the jar-file from the following links. Unpack it to the plugins-directory of your eclipse-installation into a directory called the same as the jar (without the extension, of course). Note that plugins installed in this way can not be managed using the Eclipse Configuration-Management tools.
