<p>For me, that still doesn't discover. The only thing I can think of is that the JAR that includes <span>StringSearchModelInterpolator may have a beans.xml (does it?) Also, what bean are you checking for, producers or <span>ModelInterpolator ?</span></span></p>
<p><span><span><br>
</span></span></p>
<p>Also, I like your idea of explicitly allowing extensions to have producer methods. We treat extensions as app scoped beans, so why not add that support? Do you want to create a JIRA for that?</p>

<div><font face="monospace"> bean-discovery-mode="annotated"></font></div>
<div><font face="monospace"></beans></font></div>
</div>
<div><br>
</div>
<div>…and here is a cut down, won't-compile gist of my extension class:</div>
<div><br>
</div>
<div>
<div><font face="monospace">public class MavenExtension implements Extension {</font></div>
<div><font face="monospace"><br>
</font></div>
<div><font face="monospace"> public MavenExtension() {</font></div>
<div><font face="monospace"> super();</font></div>
<div><font face="monospace"> }</font></div>
</div>
<div><font face="monospace"><br>
</font></div>
<div><font face="monospace"> private final void beforeBeanDiscovery(@Observes final BeforeBeanDiscovery event) {</font></div>
<div><font face="monospace"> if (event != null) {</font></div>
<div><font face="monospace"><br>
</font></div>
<div><font face="monospace"> //</font></div>
<div><font face="monospace"> // Types effectively bound by DefaultServiceLocator</font></div>
<div><font face="monospace"> //</font></div>
<div><font face="monospace"> </font></div>
<div><font face="monospace"> event.addAnnotatedType(DefaultArtifactResolver.class, "maven").add(SingletonLiteral.INSTANCE);</font></div>
<div><font face="monospace"><br>
</font></div>
<div><font face="monospace"> // and so on</font></div>
<div><font face="monospace"> }</font></div>
<div><font face="monospace"><br>
</font></div>
<div><font face="monospace"> private static final class Producers {<br>
</font></div>
<div><font face="monospace"><br>
</font></div>
<div><font face="monospace"> @Produces</font></div>
<div><font face="monospace"> @Singleton</font></div>
<div><font face="monospace"> private static final ModelInterpolator produceModelInterpolator(final UrlNormalizer normalizer, final PathTranslator pathTranslator) {</font></div>
<div><font face="monospace"> return new StringSearchModelInterpolator().setPathTranslator(pathTranslator).setUrlNormalizer(normalizer);</font></div>
<div><font face="monospace"> }</font></div>
<div><font face="monospace"><br>
</font></div>
<div><font face="monospace"> }</font></div>
<div><font face="monospace"><br>
</font></div>
<div><font face="monospace">}</font></div>
<div><br>
</div>
<div>Also if it matters my main loop does nothing. In other words, the test starts the container and closes it—which boots the extension of course, whereupon I notice that my
<font face="monospace">Producers</font> class gets picked up. I would have expected that I would have to programmatically add my
<font face="monospace">Producers</font> class for its producer methods to be "seen", but I don't have to. That seems odd to me.</div>
<div><br>
</div>
<div>(Frankly, what I <i>really</i> want is for those producer methods, all of which are
<font face="monospace">static</font>, to just be members of my extension class, but they are not seen in this case.)</div>
