If you want to handle a NoMatchingPlugin exception rather than simply exit then the name of the missing plugin is generally more useful than the message. The exception is specific enough that you can know what went wrong, but you cannot determine the name of the missing plugin if you want to do your own logging - only use the message that is generated. We should keep the message but expose the plugin name as well. Closes-Bug: #1410391 Change-Id: Ic93ec6583b8d7797529d36d63995ef0d8db754f1
