Well... to answer part of my own question: I noticed that this happens in the
case that I have two different modules which each use the assembly plugin.
Somehow the plugin can't resolve both pre-defined assemblies in the modules.
They're different assemblies which I reference using <descriptorRef>, and as
soon as I comment out one of the plugin configurations, the whole project
builds again.
Does this have anything to do with being only able to defined a plugin once in
a POM and having to define separate executions? How can I solve this?
Any hint, especially from the Assembly developers ;-) is greatly appreciated!
Best regards,
Eric
P.S.
Here are my two POM excerpts:

Betreff: Dependency fails, but only in reactor build
Hi
I'm having problems with a dependency that can't be found, but only in a
reactor build.
We have a project 'activity' with several modules, one of them being the
'activity-client', which uses an assembly 'batch' (a ZIP for a batch client).
We have Hudson as CI server and build every project on commit changes: The
'activity' project builds flawlessly.
[INFO] [jar:jar {execution: default-jar}]

[INFO] ------------------------------------------------------------------------
However, we also have a nightly build which builds the whole system with all
projects in one big reactor build.
Here, for some strange reason, the 'batch' assembly can't be found.
[INFO] [jar:jar {execution: default-jar}]
[INFO] Building jar:
/ige/hudson/work/jobs/esv-projects-tests__development/workspace/activity/activity-client/target/activity-client-2.2.0-SNAPSHOT.jar

[INFO] ------------------------------------------------------------------------
[ERROR] BUILD ERROR
[INFO] ------------------------------------------------------------------------
[INFO] Error reading assemblies: Descriptor with ID 'batch' not found
If within the checked out whole system I go to the directory of
'activity-client' and build it with 'mvn clean package', everything works.
If I do an 'mvn clean package' on the whole system, I get the error above.
So, clearly, the dependency exists in the repository. But sometimes it can't be
found...
How can that be or how can I check in a better way what's going wrong?
Best regards,
Eric
