I think I've got it working well enough using `-Xbootclasspath` to customize
what the router has access to when it starts up. Yeah, I have a handful of xml
files that I use to launch druid processes directly within intellij. Extensions
(and now the web-console) are a bit funny in this model as you have to
externally build them and refer to their location, but works pretty well
otherwise.
Here is my `Router.xml` for example (after fixing):
```
<component name="ProjectRunConfigurationManager">
<configuration default="false" name="Router" type="Application"
factoryName="Application">
<option name="ALTERNATIVE_JRE_PATH" value="1.8" />
<option name="MAIN_CLASS_NAME" value="org.apache.druid.cli.Main" />
<module name="druid-services" />
<option name="PROGRAM_PARAMETERS" value="server router" />
<option name="VM_PARAMETERS" value="-server
-Xbootclasspath/a:$PROJECT_DIR$/conf/router/:$PROJECT_DIR$/web-console/target/web-console-25.0.0-SNAPSHOT.jar
-Duser.timezone=UTC -Dfile.encoding=UTF-8 -Xmx256M -Xmx256M -XX:+UseG1GC
-Djava.util.logging.manager=org.apache.logging.log4j.jul.LogManager
-Dorg.jboss.logging.provider=slf4j
-Dlog4j.configurationFile=$PROJECT_DIR$/core/src/main/resources/log4j2.debug.xml
-Ddruid.host=localhost -Ddruid.zk.service.host=localhost
-Ddruid.emitter=logging -Ddruid.router.managementProxy.enabled=true
-Ddruid.extensions.directory=$PROJECT_DIR$/distribution/target/extensions/
-Ddruid.extensions.loadList=[\"druid-histogram\",\"druid-bloom-filter\",\"druid-datasketches\",\"druid-lookups-cached-global\",\"druid-basic-security\"]
-Ddruid.server.http.numThreads=50
-Ddruid.generic.useDefaultValueForNull=false " />
</configuration>
</component>
```
If you put these xml files in `.idea/runConfigurations/` then you have all
of these options to run various services in the run/debug dropdown menu:

I do this because in my experience its got a faster turn-around than
building a quickstart and attaching, can modify most stuff on the fly and live
reload, etc.
