There are a number of ways that you can export (or deploy) material from the Wolfram Workbench to use elsewhere. You can copy individual files or folders from your projects (on many systems this can work with drag and drop or cut and paste).
There are also a number of export wizards to do more complicated types of export. Some of these are generally useful, for example, saving a group of files as an archive or creating a Java jar file. In addition, the Workbench has two that are specific to Mathematica projects, for exporting to the file system and for exporting to an archive.
You can open the export wizards from the menu bar with File >
Export.... This looks like the
following.
You need to select the wizard that you want and then click Next.
