RE: [m2] How to inject values into a bean within a collection definedas a plugin parameter?

["Allison, Bob" <ro...@qwest.com>]

The configuration should look like (assuming that your definition of
parameter directory is actually specified as "private String
directory"):

<options>
  <option>
    <directory>/a/b/c</directory>
  </option>
  <option>
    <directory>/d/e/f</directory>
  </option>
</options>

I don't think that the expressions and default values available in the
Mojo are available in the classes used in this manner.  A workaround
might be to place variables which require an expression as a parameter
in the Mojo itself and have a way to propagate it to the sub-objects.

Subject: [m2] How to inject values into a bean within a collection
definedas a plugin parameter?


I have an array (same question applies to Java Collections) that is 
defined as a parameter of a Mojo:

public class MyMojo extends AbstractMojo {
...
  /**
   * @parameter
   * @required
   */
  private Options[] optionsArray;
...
}

and within the Options bean, I would like to inject properties from
Maven:

public class Options {
...
  /**
   * @parameter expression="${project.build.directory}"
   */
  private directory;
...
}

such that the plugin can be configured like:

      <plugin>
        ...
        <executions>
          <execution>
            ...
            <configuration>
              <optionsArray>
                <options>
                  ...
                </options>
                <options>
                  ...
                </options>
              </compilations>
            </configuration>
            ...
          </execution>
        </executions>
      </plugin>

Is there a way to make this happen? It seems like I should be able to do

this since Maven is creating and populating the bean classes (Options 
class).

Thanks,
Richard Allen

Re: [m2] How to inject values into a bean within a collection definedas a plugin parameter?

[Richard Allen <ri...@gtri.gatech.edu>]

For now, I've added a set method on the Options class for setting a 
default directory, which I get from a parameter in the Mojo. This is 
essentially what you suggested I could do. I just don't think it is very 
clean, and I see how it could be useful (and in this case cleaner) if 
Maven could process annotations on beans in collections that are defined 
as Mojo parameters.

Thanks,
Richard Allen
