exclude files from jar or war in eclipse

Question

Is there a way to tell Eclipse to not include specified files, directories, or patterns in a JAR or WAR?

Answer 1

to add to what @Rich_Seller said: in Eclipse Indigo:

• Select your package from the package view right click, and choose Export.
• Choose Java -> JAR file from the "select an export destination" tree.

• Click Next to go to the next page of the wizard.

• Under the "Select the resource to export" you are presented with a tree view here you can select and deselect components that will be included and excluded from the JAR.
