Hudson commented on ANY23-71:
-----------------------------

Integrated in Any23-trunk #160 (See [https://builds.apache.org/job/Any23-trunk/160/])
    Improved CLI support, introduced usage of JCommander. The commandline parsing logic has
been moved into ToolRunner as well as the production of help and version messages. This commit
includes a set of minor fixes on the patch provided by stripodi (Simone Tripodi) and it is
related to issue #ANY23-71. (Revision 1308786)

     Result = UNSTABLE

> Actual CLI - even if nicely working - can be improved in therms of of both internal architecture
and user interface.
> I see two main "issues" on current CLI:
>  * on UI, the CLI exposes internal details, since the {{ToolRunner}} requires the classname
of the tool has to be executed;
>  * on internals, each Tool has to parse the the chunk of the command line, which can
be automated.
> So my proposal is to automate, via the already working plugins discovery, the CLI arguments
parsing AND implementing a svn/git commands-based alike interface.
> My preferred choice for that is [JCommande|http://www.jcommander.org/] because:
>  * it allows binding CLI arguments to Java properties via Annotations - no more manual
parsing;
>  * it already supports a complex syntax to implement [commands|http://jcommander.org/#Complex];
>  * commands aliases can be expressed via annotations - no more needs to expose internals;
> Patch with proposal is coming
