Plugin dependency not always included to classpath

• Complexity:

  Intermediate

Plugins not always see their dependencies.

For example. I got project with parent project -

• if I run mvn install on child project mvn package runs correctly.
• if i run mvn install on parent project then child project is build with error, plugin doesn't see their dependency and fails with class not found

Example of child project
