Ability to add additional Groovy sources to script execution classpath

This can't be done by simply adding to the binding, I'll need to use a custom classloader. I'm thinking I'll do this by adding a String parameter to the mojo that could be files or URLs.

Hello,
anything new about implementing this enhancement? We are considering migration from gmaven-plugin to gmavenplus-plugin and this is holding us back.

I apologize for the crazy long delay. Thinking about this some more, I think this is actually possible today. Though it's a little clunky. Here's what I used as a test.

<execution>
  <id>pre-execute</id>
  <goals>
    <goal>compile</goal>
  </goals>
  <phase>generate-resources</phase>
</execution>
<execution>
  <id>execute</id>
  <goals>
    <goal>execute</goal>
  </goals>
  <phase>process-resources</phase>
  <configuration>
    <scripts>
      <script>
        import com.github.keeganwitt.tests.SomeProjectClass
        println new SomeProjectClass()
      </script>
    </scripts>
  </configuration>
</execution>

mvn clean gplus:compile@pre-execute gplus:execute@execute

I guess one way to make it cleaner would be if I added parameters to call the other goal(s) for you, though I'll have to think about the cleanest way to structure the parameters.
