How to exclude R*.class files from a proguard build
- by Jeremy Bell
I am one step away from making the method described here:
http://stackoverflow.com/questions/2761443/targeting-android-with-scala-2-8-trunk-builds
work with a single project (vs one project for scala and one for android).
I've come across a problem. Using this input file (arguments to) proguard:
-injars bin;lib/scala-library.jar(!META-INF/MANIFEST.MF,!library.properties)
-outjar lib/scandroid.jar
-libraryjars lib/android.jar
-dontwarn
-dontoptimize
-dontobfuscate
-dontskipnonpubliclibraryclasses
-dontskipnonpubliclibraryclassmembers
-keepattributes Exceptions,InnerClasses,Signature,Deprecated,
SourceFile,LineNumberTable,*Annotation*,EnclosingMethod
-keep public class org.scala.jeb.** { public protected *; }
-keep public class org.xml.sax.EntityResolver { public protected *; }
Proguard successfully builds scandroid.jar, however it appears to have included the generated R classes that the android resource builder generates and compiles. In this case, they are located in bin/org/jeb/R*.class. This is not what I want. The android dalvik converter cannot build because it thinks there is a duplicate of the R class (it's in scandroid and also the R*.class files). How can I modify the above proguard arguments to exclude the R*.class files from the scandroid.jar so the dalvik converter is happy?
Edit: I should note that I tried adding ;bin/org/jeb/R.class;etc... to the -libraryjars argument, and that only seemed to cause it to complain about duplicate classes, and in addition proguard decided to exclude my scala class files too.
