Update pom, use maven 3 deps.
Do not include scope, for -compile.pom scope=compile is the default.  For -dependencies.pom, adding scope=provided to DM entries adds downstream complication to fix the scope as needed.
Some clean up.
Update provided-dependencies-maven-plugin to 1.6-SNAPSHOT.
Generate a -dependencies.pom for nexus-plugin-api so we can import it in plugin-parent.
More notes.
nexus-web-utils is provided by nexus-plugin-api
Forgot type=pom on scope=import
Use plugin-parent
