You can attach files (artifacts) to an asset in two ways. If your browser supports Java applets, you can attach multiple files individually, create a folder structure in which to store files, and add links as artifacts. If your browser does not support Java applets, you can upload multiple files by browsing for them one at a time.
To use the Java applet, your browser must use an Java Runtime Environment (JRE) 1.5 Update 6 or later, or 1.6 Build 3 or later.
Asset artifacts can be attached files, references to remote development artifacts in other repositories (a URL), or an Eclipse software update site.
To attach artifacts to the asset:
Next, categorize the asset or add related assets.
When you are ready to submit the asset to the repository, click Save. If you are modifying an existing asset, click Update.
If the artifacts comprise a complete Eclipse update site (a site.xml file, a /features/ folder, and a /plugins/ folder), after you have submitted the asset, users will see a link on the Content page labeled Eclipse Update Site with a URL that they can use in the Eclipse IDE software update tool.
