[MDEP-234] Make the list and tree mojos support listing transitive dependencies for war artifact types

**[Vincent Massol](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=vmassol)** opened **[MDEP-234](https://issues.apache.org/jira/browse/MDEP-234?redirect=false)** and commented

For example, check out
http://svn.xwiki.org/svnroot/xwiki/enterprise/trunk/web/

(note: you'll need to specify the xwiki remote repo in your settings.xml as mentioned here: http://dev.xwiki.org/xwiki/bin/view/Community/Building#HInstallingMaven )

When you run "mvn dependency:tree" (or dependency:list) you get:

```
[INFO] [dependency:tree {execution: default-cli}]
[INFO] com.xpn.xwiki.products:xwiki-enterprise-web:war:2.1-SNAPSHOT
[INFO] +- com.xpn.xwiki.platform:xwiki-web-standard:war:2.1-SNAPSHOT:compile
[INFO] +- com.xpn.xwiki.platform.plugins:xwiki-plugin-watchlist:jar:1.20-SNAPSHOT:compile
[INFO] +- com.xpn.xwiki.platform.plugins:xwiki-plugin-jodatime:jar:1.4-SNAPSHOT:compile
...
```

As you can see the com.xpn.xwiki.platform:xwiki-web-standard:war dependency doesn't contain any transitive deps but it has several of them
(see http://svn.xwiki.org/svnroot/xwiki/platform/web/trunk/standard/pom.xml )

This is probably because the general artifact resolver stops at WAR packaging types. While this is probably fine when executing a maven project, it isn't when listing all project dependencies.

Thanks

Start by reproducing the reported behavior with the dependency:tree and dependency:list goals against the XWiki web example, then inspect the referenced platform/web standard pom.xml and the attached overlay-example-project.zip. Done means both listing goals include the transitive dependencies of WAR artifacts rather than stopping at the WAR dependency.
