Re: [aether-users] Maven Extension Plugins and use of Aether
|
Looks like a bug in maven, it's supposed to filter artifacts present in
the core but apparently doesn't.

So, it seems that plugin realm did load Aether after all.... complete
Aether is present in plugin realm.

Hi there,
I tried to "convert" a Maven Plugin (that is an extension too) to
Maven 3.1.x according to this doco here:
http://wiki.eclipse.org/Aether/Using_Aether_in_Maven_Plugins
But when I applied the changes explained on that page (removed
sonatype aether, added eclipse aether, and other needed POM changes,
and related code changes like package renames), I got following
breakage when given plugin executed with Maven 3.1.1 (just a message):
===
A type incompatibility occured while executing
org.sonatype.nexus:nexus-plugin-bundle-maven-plugin:1.2-SNAPSHOT:generate-metadata:
org.eclipse.aether.internal.impl.ObjectPool cannot be cast to
org.eclipse.aether.internal.impl.ObjectPool
===
This made me think that Eclipse Aether was "lifted" into extension
class loader too... (and the class loaded by Maven Core classloader
and extension classloader conflicted).
I fixed that problem by making all Ecipse Aether (and Maven Core)
related dependencies scoped as "provided".
So, a question: is the POM excerpt on that wiki page actually
missing a "provided" scope for Aether dependencies?
On a side note (a bit off topic for Aether list): I thought that
Maven will "filter out" dependencies that are already in core (like
Aether), and will provide them to plugin from core... Does it mean
that filtering does not work for extensions?
Thanks,
~t~
