[2012-06-01 14:06:03-geoTest6.3] You should check if you need to specify additional program jars.

[2012-06-01 14:06:03-geoTest6.3] Warning: there were 1773 unresolved references to classes or interfaces.

[2012-06-01 14:06:03-geoTest6.3] You may need to specify additional libraryjars (using'- libraryjars')

[2012-06-01 14:06:03-geoTest6.3] or perhaps the'- dontskipnonpubliclibraryclasses' option.

[2012-06-01 14:06:03-geoTest6.3] Warning: there were 1 instances of library classes depending on program classes.

[2012-06-01 14:06:03-geoTest6.3] You must avoid such dependencies, since the program classes will

[2012-06-01 14:06:03-geoTest6.3] at proguard.Initializer.execute (Initializer.java:308)

[2012-06-01 14:06:03-geoTest6.3] at proguard.ProGuard.initialize (ProGuard.java:210)

[2012-06-01 14:12:33-geoTest6.3] Proguard returned with error code 1. See console

Solution: because of the tripartite jar package, we need to add "- dontwarn" to the proguard.cfg

As follows:

Proguard.cfg all configuration

-dontwarn

-optimizationpasses 5

-dontusemixedcaseclassnames

-dontskipnonpubliclibraryclasses

-dontpreverify

-verbose

-optimizations! codeUniverse simplificationplicationlapse.
