Now as part of the upload of your jar to the maven repository at
ibiblio you can include the sources, making them available to all your
users, helping you to find and solve bugs, hopefully ;).

For instance, to generate the eclipse project for a maven 2 project with the sources attached, you can run

mvn eclipse:eclipse -Declipse.downloadSources=true
 

Read the instructions to make an upload bundle, now with sources!
