Hi Joe,
You could try adding
<scope>provided</scope>
to the org.apache.geronimo.configs/jasper/{version}/car dependency in
the pom.xml. I 've seen a similar error like this before and by
adding the scope fixed it.
Thanks Lin. That does indeed solve (more correctly avoid) the problem.
However, adding <provided> means that the dependency will not be
downloaded and must already be available. That's not necessarily a bad
thing, but it could potentially limit the server configurations upon
which the sample or other plugins can be installed. That's something
that we can consider for the samples but in any case I think we also
need to get this scenario working ... where a dependency is not marked
as "provided" but can still be resolved with a different dependency via
the artifact-alias that can be (or already is) installed on the given
server instance.

Thanks,
Lin

Can you check if the plugin installer gbean is using the artifact resolver

Thanks for the help David.
I'm still not sure exactly why this isn't working yet but I did learn a few
things:
- The PluginInstallerGBean is using an ArtifactResolver as it should be and
not accessing the repository directly.
- Checking the ArtifactResolver instance shows that it is actually using the
ExplicitDefaultArtifactResolver class.
- When I install my compatibility plugin I can see the point in the
PluginGBeanInstaller where it calls ExplicitDefaultArtifactResolver to add
the alias entries.
- It appears to be the same instance of the ExplicitDefaultArtifactResolver
for both adding the entries and when we later check to for items like the
jasper 2.1 car file dependency later on.
- When we query the artifact resolver for the jasper configID (via
queryArtifacts()) it does not come back with a match for some reason. It
seems that queryArtifacts() is inherited from DefaultArtifactResolver and
it's not clear to me if this class takes into consideration aliases that
were added.
still looking ...
Joe
thanks

I attempted to create a version compatibility plugin such that plugins
with dependencies on 2.1 artifacts could attempt to be installed in a
2.2-SNAPSHOT server image (mapping 2.1 car artifacts to 2.2-SNAPSHOT car
artifacts). However, thus far I'm not having any success.
The plugin is fairly simple. Just a bunch of entries for artifact
aliases and no other content:
<plugin-artifact>
...
<artifact-alias
key="org.apache.geronimo.configs/jasper//car">org.apache.geronimo.configs/jasper/2.2-SNAPSHOT/car</artifact-alias>
<artifact-alias
key="org.apache.geronimo.configs/jasper/2.1/car">org.apache.geronimo.configs/jasper/2.2-SNAPSHOT/car</artifact-alias>
...
I also verified that after installing the compatibility plugin that the
entries are added to the artifact-aliases.properties file in var/config:
...
org.apache.geronimo.configs/jasper//car=org.apache.geronimo.configs/jasper/2.2-SNAPSHOT/car
org.apache.geronimo.configs/jasper/2.1/car=org.apache.geronimo.configs/jasper/2.2-SNAPSHOT/car
...
Yet, even with these entries, I still get essentially the same error
attempting to install samples created for 2.1 in a 2.2-SNAPSHOT server as I
had without the artifact-alias entries. I showed the jasper entries above
because that is the missing dependency when I attempt to install the Tomcat
JSP example plugin created for 2.1 on 2.2-SNAPSHOT (see error below). I had
similar results on a 2.1.1 server when I attempted to use a another
compatibility plugin mapping 2.1 cars to 2.1.1. Am I missing something
obvious?
