Increment Version Automatically

If this option is checked, MTJ will automatically increment the Midlet Version parameter every time the MIDlet suite is repackaged.

Note that, if a version number of the form x.y.z is incremented so that "y" or "z" exceeds 99, this number "rolls" back to zero, and the next number up is incremented. This is done because a significant number of phones generate errors if presented with a JAD file that contains a version number with a three-digit component in it.

Excluded Properties | This area of the packaging preferences allows you to exclude certain of the MIDlet properties from the manifest file that is packaged within the deployed jar as part of the packaging operation. By default, the MIDlet-Jar-URL and MIDlet-Jar-Size entries are excluded.
