proguard-maven-plugin suggestion

[velo]

Hi,

I'm using proguard-maven-plugin and I made a small change on it that I
wanna to share.

On my application I wanna run the unit tests against the obfuscated
code, to be sure if it will work at runtime. So, I changed proguard-
maven-plugin to allow obfuscation of classes directory (instead of
obfuscating the final jar).

It is a very simple change, but can be very useful to many others.

Hi Velo
I did the requested change differently.

Now you may specify <injar>classes</injar>
The plugin will detect if this is jar(file) or directory and will
produce different result.
The version 2.0.4-SNAPSHOT will support this.

See the test project:
https://pyx4j.com/svn/pyx4me/pyx4me-tests/proguard-maven-plugin-classes-test
