> Here's an error
> [reported|https://github.com/brooklyncentral/clocker/issues/345] by a user of
> Clocker:
> {code}
> Remote catalog url classpath://io.brooklyn.clocker.swarm:swarm/swarm.bom
> can't be fetched.: Error getting resource
> 'classpath://io.brooklyn.clocker.swarm:swarm/swarm.bom' for
> classload:[OSGi::0.0.0[[CatalogBundleDto{symbolicName=null, version=null,
> url=https://oss.sonatype.org/service/local/artifact/maven/redirect?r=snapshots&g=io.brooklyn.etcd&a=brooklyn-etcd&v=2.3.0-SNAPSHOT},
> CatalogBundleDto{symbolicName=null, version=null,

> AggregateClassLoader[],
> AggregateClassLoader[AggregateClassLoader[AggregateClassLoader[org.apache.brooklyn.util.javalang.LoadedClassLoader@3d68e54],
> AggregateClassLoader[]]]]]]: IOException: Error accessing
> classpath://io.brooklyn.clocker.swarm:swarm/swarm.bom: java.io.IOException:
> io.brooklyn.clocker.swarm:swarm/swarm.bom not found on classpath
> {code}
> The important information is right at the start: swarm.bom can't be fetched.
> The rest is noise only suitable for a debug log.
> Brooklyn leaks too much Java to end users. For example, if you try to add
> this blueprint to the catalogue:
> {code}
> brooklyn.catalog:
> item:
> - type: org.apache.brooklyn.entity.software.base.VanillaSoftwareProcess
> {code}
> The error you receive is "java.util.ArrayList cannot be cast to
> java.util.Map" (i.e. the hyphen shouldn't be there). There is no indication
> of where in the blueprint the error occurred and what the expected syntax is.
> A third common mistake is typing {{brooklyn.config}} in DSL strings. The
> correct value is {{brooklyn:config}}. It causes problems that are hard to
> trace. We should either permit the former or provide "did you mean this?"
> feedback.
> Lastly, when bundles' dependencies cannot be wired the user is told "cannot
> load catalogue item". Brooklyn would save them a lot of time by telling them
> why this is the case.
