在Android Studio中使用Gradle来压缩库时，Proguard遇到了Lombok库的问题。我找到了一些配置信息来修复butterknife，我们使用的另一个注释库。
-keepattributes *Annotation*
-dontwarn butterknife.internal.**
-keep class **$$ViewInjector { *; }
-keepnames class * { @butterknife.InjectView *;}
有没有人知道要添加的标志让Lombok感到高兴。
Proguard配置文件
# This is a configuration file for ProGuard.
# http://proguard.sourceforge.net/index.html#manual/usage.html
# Optimizations: If you don't want to optimize, use the
# proguard-android.txt configuration file instead of this one, which
# turns off the optimization flags. Adding optimization introduces
# certain risks, since for example not all optimizations performed by
# ProGuard works on all versions of Dalvik. The following flags turn
# off various optimizations known to have issues, but the list may not
# be complete or up to date. (The "arithmetic" optimization can be
# used if you are only targeting Android 2.0 or later.) Make sure you
# test thoroughly if you go this route.
#-optimizations !code/simplification/arithmetic,!code/simplification/cast,!field/*,!class/merging/*,!code/allocation/variable
-dontobfuscate
#-optimizationpasses 5
-allowaccessmodification
-dontpreverify
# The remainder of this file is identical to the non-optimized version
# of the Proguard configuration file (except that the other file has
# flags to turn off optimization).
#-dontusemixedcaseclassnames
#-dontskipnonpubliclibraryclasses
-verbose
-keepattributes *Annotation*
-dontwarn butterknife.internal.**
-keep class **$$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.**

Warning: there were 10560 unresolved references to classes or interfaces.
You may need to add missing library jars or update their versions.
If your code works fine without the missing classes, you can suppress
the warnings with '-dontwarn' options.

Warning: there were 128 instances of library classes depending on program classes.
You must avoid such dependencies, since the program classes will
be processed, while the library classes will remain unchanged.

我添加了一些标志来禁止我项目中包含的库的警告，这样就可以了。
-dontwarn javax.**
-dontwarn lombok.**
-dontwarn org.apache.**
-dontwarn com.squareup.**
-dontwarn com.sun.**
-dontwarn **retrofit**
答案 1 :(得分：5)
如果您在gradle构建文件中使用compile指令，请将其更改为provided
在Eclipse中，有一个类似的解决方案，你可以将jar分解为你在libs中包含的lombok-api.jar。我试着寻找指示，但无法找到解释你如何做到这一点的页面（这是一年多以前，所以它可能已经改变了）。
感谢Roel（下方），这里是使用的命令行：
java -jar lombok.jar publicApi
