Joerg Schaible commented on MNG-5255:
-------------------------------------
Note that the dependency plugin does not use the dependency resolution
algorithm of M3 and might therefore not show the reality. For M3 you have to
look at the debug output when starting Maven with -X option to be sure.
> Dependency with 'provided' scope has its transitive dependency included in
> final artifact

> Issue Type: Bug
> Components: Dependencies
> Affects Versions: 3.0.4
> Environment: Apache Maven 3.0.4 (r1232337; 2012-01-17 00:44:56-0800)
> Maven home: D:\bin\apache-maven-3.0.4

> Expected: A dependency declared with a scope of 'provided', along with any
> transitive dependencies, should not be included in the final artifact.
> Actual: I have a dependency, jsp-api, declared with 'provided' scope. This
> dependency has a dependency of its own, servlet-api. The servlet-api.jar is
> being included in the web-inf/lib folder of the resultant war file.
> Background: We recently upgraded from Maven 2.2.1 to Maven 3.0.4. The problem
> was not witnessed until after the upgrade.
> Steps to Reproduce: Run mvn install, then have a look at the web-inf/lib
> folder. Notice that the servlet-api.jar has been included.
> Additional Info: It seems that I can only reproduce this behavior when
> declaring a specific dependency in my pom, spring-ldap. Here is the
> dependency tree for the given pared-down project (attached):
> --- maven-dependency-plugin:2.1:tree (default-cli) @
> provided-scope-not-working ---
