Proguard build error with Lombok annotation library
Proguard is having problems with the Lombok library when using Gradle in Android Studio to process the library. I found some config information to fix butterknife, another annotation library we are using.
-keepattributes *Annotation*
-dontwarn butterknife.internal.**
-keep class **$$ViewInjector { *; }
-keepnames class * { @butterknife.InjectView *;}
Does anyone know flags that need to be added to make Lombok happy.
Proguard configuration file
# This is a configuration file for ProGuard.
# http://proguard.sourceforge.net/index.html#manual/usage.html
# Optimizations: If you don't want to optimize, use the
# proguard-android.txt configuration file instead of this one, which
# turns off the optimization flags. Adding optimization introduces
# certain risks, since for example not all optimizations performed by
# ProGuard works on all versions of Dalvik. The following flags turn
# off various optimizations known to have issues, but the list may not
# be complete or up to date. (The "arithmetic" optimization can be
# used if you are only targeting Android 2.0 or later.) Make sure you
# test thoroughly if you go this route.
#-optimizations !code/simplification/arithmetic,!code/simplification/cast,!field/*,!class/merging/*,!code/allocation/variable
-dontobfuscate
#-optimizationpasses 5
-allowaccessmodification
-dontpreverify
# The remainder of this file is identical to the non-optimized version
# of the Proguard configuration file (except that the other file has
# flags to turn off optimization).
#-dontusemixedcaseclassnames
#-dontskipnonpubliclibraryclasses
-verbose
-keepattributes *Annotation*
-dontwarn butterknife.internal.**
-keep class **$$ViewInjector { *; }
-keepnames class * { @butterknife.InjectView *;}
-keep public class com.google.vending.licensing.ILicensingService
-keep public class com.android.vending.licensing.ILicensingService
# For native methods, see http://proguard.sourceforge.net/manual/examples.html#native
-keepclasseswithmembernames class * {
native <methods>;
}
# keep setters in Views so that animations can still work.
# see http://proguard.sourceforge.net/manual/examples.html#beans
-keepclassmembers public class * extends android.view.View {
void set*(***);
*** get*();
}
# We want to keep methods in Activity that could be used in the XML attribute onClick
-keepclassmembers class * extends android.app.Activity {
public void *(android.view.View);
}
# For enumeration classes, see http://proguard.sourceforge.net/manual/examples.html#enumerations
-keepclassmembers enum * {
public static **[] values();
public static ** valueOf(java.lang.String);
}
-keep class * implements android.os.Parcelable {
public static final android.os.Parcelable$Creator *;
}
-keepclassmembers class **.R$* {
public static <fields>;
}
# The support library contains references to newer platform versions.
# Don't warn about those in case this app is linking against an older
# platform version. We know about them, and they are safe.
-dontwarn android.support.**

If you are using directive compile
in your gradle build file then change it toprovided
There is a similar solution in Eclipse where you can split the jar into lombok-api.jar which you include in your libraries. I've tried looking for instructions, but can't find a page explaining how you would do this (this was over a year ago, so it may have changed).
Thanks to Roel (below), here's the command line used:
java -jar lombok.jar publicApi
