Hi Mark,
I like your idea that changing the exclude property file. In my mind,
anything to make it clear and easy will be great.
In my original plan, I was just trying to fix the classlib build.xml,
add some new target in that. Yes if we only require some excluded jars we
can use the exclude list.
To use a new folder deploy_select is try to avoid some confliction,
e.g, if someone build full harmony, and then build harmony-select again, he
still has extra jars in the deploy folder.
Both Java5 or Java6 is OK if we make it no side-effect with other build
targets.
Will try the exclude list now.
