[tycho-user] Tycho build extension not configured when running before pa

[Carsten Reckord <reckord@xxxxxxxx>]

Hi,

I am trying to build an eclipse-repository project and process the 
generated metadata in between build steps.

Since I want to edit the repository's own p2content.xml before the site 
gets assembled (in order do some processing on the categories) as well 
as the final content.xml (in order to add repository references and do 
some more processing), I would like to move the 
tycho-p2-publisher-plugin to an earlier phase to get the execution order 
for my processing right.

But something like

         <plugin>
            <groupId>org.eclipse.tycho</groupId>
            <artifactId>tycho-p2-publisher-plugin</artifactId>
            <executions>
               <execution>
                  <id>publish-categories</id>
                  <phase>process-resources</phase>
                  <goals>
                     <goal>publish-categories</goal>
                  </goals>
               </execution>
            </executions>
         </plugin>

with any phase earlier than package leads to

> LifecycleExecutionException: Failed to execute goal org.eclipse.tycho:tycho-p2-publisher-plugin:0.22.0:publish-categories (publish-metadata):
> Execution publish-metadata of goal 
org.eclipse.tycho:tycho-p2-publisher-plugin:0.22.0:publish-categories 
failed: Tycho build extension not configured for MavenProject

Judging by the exception, it seems the target platform is not available 
at this point:

Is there any way around this?
