Ate Douma commented on JS2-1227:
--------------------------------
I determined the problem why the jetspeed-mvn:unpack plugin fails with Maven 3.
In the unpack plugin (and the others), it used the Maven
PluginDescriptor.getIntroducedDependencyArtifacts() method to retrieve
dependencies configured for the plugin itself only.
That allowed an convenience usage of the plugin when only a single dependency
(artifact) was defined as it then could determine itself automatically which
artifact that was.
However, although this method is still defined on the Maven PluginDescriptor,
Maven 3 now simply always returns an EMPTY_COLLECTION. So much for backwards
compatibility ...
As result, I had to refactor the plugins who relied on this method to fallback
to the PluginDescriptor.getArtifacts() method. Which does return *all*
dependencies within scope, so not just the one explicitly defined for the
plugin.
And, the convenience usage of not having to specify the artifact to unpack if
only one is defined no longer is possible!
Meaning: every unpack configuration now either has to specify an
<artifact>${groupId}:${artifactId}:${packaging}</artifact> or a <file>[file
location]</file> element.
Other than making the required configuration changes for this, Jetspeed-2
portal trunk then builds with maven 3 just fine.
I've already committed the needed changes.
I'll keep this issue open however as so far I only ensured the jetspeed-2
portal project is now building fine with Maven 3 again.
The other jetspeed-2 applications projects like j2-admin also needs to be
checked and if needed cleaned up/fixed, something which I'll look into later
this week or next week.
