1. First, download the correct version of Eclipse for your platform which is compatible with the version of JBoss Tools you plan to install. For example, you may choose the Eclipse 3.4.2 Ganymede JEE Bundle in order to install JBoss Tools 3.0. If no bundle is available for your platform, or if you would prefer a smaller download, choose the Eclipse 3.4.2 Platform Runtime Binary - Eclipse will then download only the bare essentials needed for JBoss Tools. Fedora users can simply `yum install eclipse-platform`.

• Eclipse 3.4.2 Ganymede Bundles
• Other Versions, Platforms, Options

2. Next, unpack Eclipse somewhere on your drive, eg., ~/eclipse or c:\eclipse

3. If you do not already have Java 5 or 6 installed and in your path, download and install that. Fedora users, `yum install java-1.6.0-openjdk-devel`. Note that gcj/gij is not supported.

4. Double-click the Eclipse icon, or open a terminal and run `~/eclipse/eclipse -vm /path/to/bin/java`. See also more startup options.

5. When Eclipse starts, go to Help > Software Updates... > Available Software > Manage Sites... > Add...

6. Paste in the URL of the update site you've chosen. See the complete list here or here. On some platforms, you may also be able to drag and drop the link from your browser directly into Eclipse.

7. If installing from an update site zip such as JBossTools-3.0.3.GA.zip, download the zip, then in the above image click the Archive... button to browse for the zip. DO NOT UNZIP IT.

8.Click the Select features to install, then click Install...

9. If you encounter problems resolving dependendies, you can click 'Manage Sites...' and manually add or enable missing sites.

Here are the sites required for JBoss Tools 3.0: 

• BIRT 2.3 Update Site
• AspectJ Development Tools Development Update Site
• Equinox Aspects Development Update Site

10. Install. Restart when prompted.

11. After fetching all the features and plugins for installation, you may be prompted that your selection contains unsigned jars. This is normal, and should not be seen as an "unsafe" installation. Simply accept the warning and continue.
