问题
Using Wildfly 8.2.0.Final, which I believe uses Weld 2.2, I've reproduced this issue with 2 simple classes in a Maven multimodule project. One produces a javax.ws.rs.client.Client, another has an injection point for the same. Arquillian deployment fails with WELD-001408: unsatisfied dependencies.
The producer is in a library jar that gets included in the WEB-INF/lib for the consumer. Producer has a beans.xml in the META-INF with discovery-mode=annotation and the consumer has one in WEB-INF with discovery-mode=all.
Steps to reproduce:
Download this project and run mvn clean install from the root directory.
This is a critical bug. There're some other SO posts about Weld unsatisfied dependencies but most of them are because a beans.xml was missing. With CDI 1.2, beans.xml is optional, though my example does have couple. Any ideas?

After days of trying to reproduce the issue in another project, but in vain, I reduced the original project to a CDI produce and a consumer and posted the code in JBoss forum and also opened a JIRA WELD-1921. Martin Kouba found out that the problem was caused by using the wrong Produces annotation! Instead of javax.enterprise.inject.Produces, I had javax.ws.rs.Produces. This obviously wasn't intentional and must've happened when I auto-imported the package in Eclipse and somehow picked the wrong one!
There were some other issues too but nothing I couldn't solve myself. Thanks a ton Martin.
