Re: [tycho-dev] [pomless] maven-deploy-plugin configuration

[Christoph Läubrich <laeubi@xxxxxxxxxxxxxx>]

@Hannes I'm glad that this feature is found useful by others :-)

@Dirk: First of all MANY thanks for describing the workflow! I'm not 
very familiar with the maven-deploy-plugin but would it help if pomless 
would generate the following in the "non-artifact-poms":

<build>
  <plugins>
    <plugin>
      <artifactId>maven-deploy-plugin</artifactId>
        <configuration>
          <skip>false</skip>
        </configuration>
    </plugin>
  </plugins>
</build>

or can tycho-pomless do anything else to tell the maven-deploy-plugin 
that some parts are only intermediates?
