             Summary: Patch-gen tool should provide users with better error messages
                 Key: WFLY-2104
                 URL: https://issues.jboss.org/browse/WFLY-2104
             Project: WildFly
          Issue Type: Feature Request
          Components: Patching
            Reporter: Vaclav Tunka
            Assignee: Emanuel Muckenhuber


Patch-gen tool should provide better error messages to user. Eg. telling what exactly is wrong, instead of listing the full usage.

[vtunka at voidray tool]$ ./tool.sh --create-template --cumlative 6.2.0
USAGE:
patch-gen.sh --create-template --one-of     [patch-id]
patch-gen.sh --create-template --cumulative [patch-id]
this will create a patch-config-[patch-id].xml
if this is not desired just append --std.out

There is a typo in --cumlative instead of --cumulative, but the tool doesn't say that, and user is left to explore possible sources of error.
