I recently added a couple of new plugins to my default set of Eclipse plugins, which you might like.
Resource bundle editor
The ResourceBundle editor plugin for eclipse allows you to easily edit the resource bundles in your project. It can give you a very nice overview of all the available values for a key in your resource bundles.
Recently Sandro Boehme was so kind to create a version of his JCR Browser plugin to be able to connect with Hippo Repository.
It's a nice Eclipse plugin, which allows you to browse the Hippo JCR repository based on Apache Jackrabbit. It's a view only plugin, but it can be very usefull just to have some insight on what kind of information is in your repository.
The Hudson Eclipse plugin ,created by Joakim Recht, allows you to monitor the build status of your projects from within Eclipse.
This plugin allows you to see the current build status and console output. You can also trigger your builds from within Eclipse, which makes it quite a handy little addition to your development environment.
