Proguard configuration

[dadouf]

Hi,

I have a lot of trouble using this library in a production environment, that is with Proguard enabled (minifyEnabled true).

If I don't specify any rule, I get these warnings during compilation:

If I try to keep everything in the com.tojc.ormlite package and the javax package with:

-keep class com.tojc.**
-keepclassmembers class com.tojc.** { *; }
-keep enum com.tojc.**
-keepclassmembers enum com.tojc.** { *; }
-keep interface com.tojc.**
-keepclassmembers interface com.tojc.** { *; }

-keep class javax.**

I still get the same errors.

If I simply ignore the warnings, with:

-dontwarn com.tojc.ormlite.android.compiler.**
-dontwarn com.squareup.javawriter.**

It compiles fine, obviously, but it crashes at runtime:

I sense there's a problem with javax being obfuscated by Proguard, but I lack the insight that you have to determine the right rules.

Note: I used version 1.0.4.
Thanks for your help, I'm sure it'll help others in the future!

An update on that: it seems that simply adding that line solved problem...

-libraryjars <java.home>/lib/rt.jar

(With <java.home> written as is, don't replace it by a path to your java home).

So it seems my problem is solved, but could you confirm? And maybe mention this in the README cause plenty of Android projects do use ProGuard...
