Tell where the error lies in izpack.yml

[DavidPerezIngeniero]

A message like this is not very self-explanatory:

[error] (rds/izpack:createXml) org.clapper.sbt.izpack.IzPluginException: null; Can't construct a java object for tag:yaml.org,2002:org.clapper.sbt.izpack.IzPackYamlConfig; exception=Cannot create property=panels for JavaBean=org.clapper.sbt.izpack.IzPackYamlConfig@2a698ad0; Cannot create property=panel for JavaBean=org.clapper.sbt.izpack.Panels@63017af3; Cannot create property=action for JavaBean=org.clapper.sbt.izpack.Panel@11f518d3; Cannot create property=id for JavaBean=org.clapper.sbt.izpack.Action@7552cf3b; Unable to find property 'id' on class: org.clapper.sbt.izpack.Action

I miss at least the line number.

I'm not sure this is fixable. I'm using SnakeYaml to do the parsing, so by the time I see the parsed output, the line numbers are gone.

Another case:

This isn't very informative either! :-(

I lose the information of the original exception.

 catch {
   case e: Throwable =>
     val e2 = findCorrectException(e)
   if (logLevel == LogLevel.Debug)
     e2.printStackTrace()
   izError(e2.getMessage)
 }
