Description

I have the following in my main pom

<build>
 <pluginManagement>
  <plugins>
   <plugin>
    <groupId>org.apache.servicemix.plugins</groupId>
    <artifactId>maven2-jbi-plugin</artifactId>
    <version>1.0-SNAPSHOT</version>
    <extensions>true</extensions>
   </plugin>
  </plugins>
 </pluginManagement>
</build>

If i try to add it to the modules, the first time, maven complains that it can not download the plugin.
If i remove the <extensions> tag, all works, but i need it

so, how is the pluginManagement item getting triggered? Do you have the plugin referenced in the main part of your build in the main POM or something?

The current Geronimo build has the same problem. Order of build doesn't matter - it just needs to be used somewhere as the extensions are pre-loaded.

Workaround is to deploy a snapshot of the plugin so that Maven downloads the snapshot, uses that to load the extensions, builds the plugin, then reloads the new plugin when it is used.

Any status on when this will make it into a m2 release?

no, i haven't tested this use case with the new build plan. It may work, but I haven't tried yet.

Hi John,

Do you have any news on that?

Flex-mojos is suffering with this too.

This actually works on Maven 2.2.1, but seems to have regressed in 3.0-SNAPSHOT. Attaching the test program (artifacts must not be in the local repository for failure to appear), as I do not currently have time for a full IT/investigation.

Until we extend the POM to allow to distinguish between different types of extensions in order to tell which of them can loaded sometime later during the build, there is no path forward.

putting into 3.1 so that such an extension to the POM can be made so that this can be made to work again

I didn't investigate enough originally, and the attached IT isn't complete to test this. This wasn't fixed in 2.2.1 - it doesn't actually load the extension, as it never ended up in the effective POM. Maven 3 now does that, and attempts to load the extension, which is not built.

The workaround to this, if suitable, is to use an older version of the plugin to use throughout the build.

Does anybody know what the concrete work would be to solve this issue? We struggle with this in NPanday...

We really need this on the xwiki project too. Using an older version is not really a solution since when you make a change you need to use the latest version. We have some automated script to release XWiki which uses the maven release plugin and doing a 2 step release with the release plugin is really difficult (and probably impossible actually).
