Also, in the context of a WAR project, <scope>provided</scope> and <optional>true</optional> have different semantics when it comes to inclusion in the manifest's Class-Path or not.
(See: http://maven.apache.org/plugins/maven-war-plugin/examples/war-manifest-guide.html ) In my experience, it is usually better to mark dependencies in a JAR project as <optional>true</optional>, since provided scope would be a strong assumption about the context that the JAR is going to be used in. YMMV. -Olivier On Fri, 2008-05-09 at 19:45 -0400, Brian E.
