[jira] Commented: (MSITE-484) Support adding and overriding report
plugins in new maven-site-plugin 3.x reportPlugins configuration format
[ https://jira.codehaus.org/browse/MSITE-484?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=273106#comment-273106 ]
Herve Boutemy commented on MSITE-484:
-------------------------------------
yes, a new mecanism is to be defined in Maven core, since plugin configuration inheritance works at DOM level, without any interpretation of any content.

> Key: MSITE-484

> Project: Maven 2.x and 3.x Site Plugin
> Issue Type: Bug

> Environment: 3.0-beta-1-SNAPSHOT
> Reporter: Michael Pilquist

> When using the new configuration format for reportPlugins, it appears that there's no way to:
> - Add a report plugin to a submodule
> - Override the configuration of a report plugin in a submodule
> Using the old <reporting> section, both of these use cases were supported. For large, multi-module builds, it is problematic having to respecify all reporting plugins in any submodule pom that needs to either add an additional reporting plugin or change the configuration of a reporting plugin.
> Attached is a sample project that has a parent POM configured with project-info-reports and javadoc plugin and a submodule configured with jxr plugin and javadoc plugin. The relevant output is here:

> Looking at the maven-site-plugin code, it appears the the reportPlugins parameter is just a regular array parameter. AFAIK, there's no way to merge list configuration items. Other plugins have worked around this by defining additional mojo parameters (e.g., maven-eclipse-plugin and buildCommands / additionalBuildCommands -- http://maven.apache.org/plugins/maven-eclipse-plugin/eclipse-mojo.html). This isn't the most flexible option though as it only solves 1 level inheritance.
