Eclipse allows you to export Jars via the Export/Java/Jar File right click option from the package or project explorer on a project.
The export wizard has a number of options. I generally create one jar with the class files in and a second for the sources.
It is obviously somewhat tedious and error prone to select all the options each time, so fortunately on the export wizard, on the Jar Packaging Options page you can select the option to Save the description of this jar in the workspace.
This will then create a .jardesc file with all the options on. Later you can simply right click a previously saved .jardesc and select Create Jar to recreate the jar with the same options that you saved.
