Ok, did some further investigation: What I have is an extension
containing a class (C). This class is referenced in the fields of
two different Mojos, the fields are not even initialized by Plexus.
Looking at the new DefaultExtensionManager, I suppose this cannot
work any more, because the newly introduced extension container has
its own ClassRealm. When any of the plugins is instantiated by the
PluginManager, I get a NoClassDefFoundError for class C.
Does this mean that I cannot access classes from extensions in a
plugin any more? And that I cannot share data between plugins,
except by using JDK and Maven core classes?
This would be a major setback for us. We're using maven to build C+
+ projects and wrote a bunch of plugins, which absolutely need to
share data.
Provided they are in the same plugin you can always use the plugin
context.
We also wrote a huge slew of plugins for C development and we created
a facility called the BuildContext for 2.1 because all these other
methods were brittle and we wanted a stated way to do it.
I'll think about a work around, you can probably use the plexus context.

An extension should still work there, as long as the things are
instantiated in the extension itself - sounds like doing it in
the plugin is the problem. Is there a reason it must be there, or
can you use the plexus component lifecycle to do the instantiation?
Other than extensions, you can use plugin dependencies in most
cases (though doesn't sound suitable here). You might also be
able to use the plugin context to share the values instead of an
extension (though not if you are introducing new types, so
probably not the case here also).

Hi,
we use several plugins that need to share data. This as done by
creating an extension containing some "container" classes, and
adding an extension to the project's pom. These container
classes are instantiated in a plugin using Plexus. However,
since 2.0.5, this stopped working, because extensions now have
their own container and the Plugin throws a NoClassDefFoundError.
Is there new way/workaround for this?

Jochen
