Yeah, the confusing thing here is that even though SwitchYardFacet is in the same module (different resource-root) as the Facet that is requesting it, it cannot find the class. Does that sound possible? Is this maybe a problem with weld not scanning/loading SwitchYardFacet for some reason?

Stuart,

The missing class is SwitchYardFacet.class.      The thing that I don't understand is that it is contained in one of the other resource roots, but not the one that makes this reference.     Shouldn't it be able to find it?

The other strange thing is that this worked in Forge 1.0.0.Beta3.

Actually looking at that stack trace I would say that the missing class is one of:

{ DependencyFacet.class, PackagingFacet.class, SwitchYardFacet.class }

Based on the fact that it is dying inside parseClassArray(). 

Are all these classes in the same module? An easy way to experiment is to set a breakpoint, and then in the watches window do CamelFacet.class.getClassLoader().loadClass("com.blagh.DependencyFacet") and see which ones are not accessible.

Hey Stuart,

I have a favor to ask regarding Weld/JBM. If you have a few seconds, could you take a look at something for me? The steps to reproduce this problem are in the issue (and this email thread,) but I'm pretty much at a loss to why this isn't working. We're getting that lovely sun.reflect.annotation.

TypeNotPresentExceptionProxy again, this time on a class that is in a resource root of the same module, but doesn't seem to be found.

I'd love to hear your thoughts.

I take that back. I'll have to do more digging. After adding log4j to the module.xml, I receive the same error that you did.

Ok well, once I turned on logging I was able to figure out the root cause, but I don't know exactly why yet. I'm assuming that the stack trace is fairly obvious. The question is. "What is the correct way to resolve it?"

Side note: I really need to add a logging toggle in Forge itself, but it would need to go into the launcher, just haven't gotten around to it yet. Currently, one needs to edit the build to enable logging *gulp* (Search for "LOGGING") in the source and you'll see what I mean :/ That might be my tomorrow (in addition to working on this.) I'm going to be cutting a Beta5 very soon because of some issues in the recent Beta4.

Here's the steps to reproduce (there's quite a few, sorry for that, we
should have this down to two in the next release) :

Download
http://downloads.jboss.org/switchyard/releases/v0.3/switchyard-installer-0.3.0.Final.zip
unzip switchyard-installer-0.3.0.Final.zip
cd switchyard-installer-0.3
unzip a jboss-as-7.0.2 somewhere to install into, give that location to
the installer
Answer (y) that you would like to install the SwitchYard Forge plugin
If you have FORGE_HOME set to forge-1.0.0.Beta4 or SNAPSHOT, it may
error out on trying to write to the ~/.forge/plugins/installed.xml
because JARs have moved around - in this case add the following line to
installed.xml :

<installed>
<plugin name="org.switchyard.switchyard-forge-plugin" slot="0.3.0.Final"/>
</installed>

Change FORGE_HOME to forge-1.0.0.Beta4 or SNAPSHOT

Edit
~/.forge/plugins/org/switchyard/switchyard-forge-plugin/0.3.0.Final/module.xml
Change <module name="javax.enterprise.cdi-api"/>
to <module name="javax.enterprise.api"/>
Change <module name="org.jboss.forge.shell-api"/>
to <module name="org.jboss.forge.shell.api"/>
