I've never found that to be perfectly clear either. Would you mind filing a jira with a patch?
-----Original Message----- From: Tim Kettler [mailto:[EMAIL PROTECTED] Sent: Friday, August 24, 2007 2:35 PM To: Maven Users List Subject: Re: provided dependencies Hi, the description of the dependency scope table referenced below would be clearer (at least in my opinion) if it would read: "Each of the scopes affects transitive dependencies in different ways, as is demonstrated in the table below. If a dependency is set to the scope in the left column, __transitive dependencies of that dependency__ with the scope across the top row will result in a dependency in the main project with the scope listed at the intersection. If no scope is listed, it means the dependency will be omitted." So what is most probably happening is that you have declared another non-provided-scoped dependency (to commons-logging for example) which depends on the servlet-api non-transitively (see the pom of commons-logging [1]). Therefore the servlet-api gets pulled in though your direct dependency has scope provided. So as Tommy wrote your best chance is to use the dependency-plugin to print your dependency tree and see which other dependency depends on the servlet-api and then exclude it from that dependency. -Tim [1] http://repo1.maven.org/maven2/commons-logging/commons-logging/1.1/common s-logging-1.1.pom DM schrieb: > Thanks for the reply.
