I was busy adding logging to a project today and added a logback.xml file to a resource directory under src/main. When running the application the logback.xml file was not being picked up. It turns out the resource directory must be added to the build path. A quick reminder how to do this:

• Right click on the project
• Select Build Path | Configure Build Path…
• Select the Source tab
• Click Add Folder…
• Check the check box of the folder to add
• Click OK
• Click OK

Everything should be working now.
