android - Lombok注释库导致Proguard构建失败

在Android Studio中使用Gradle编译Lombok库时，Proguard出现问题。我找到了一些配置信息来修复Butterknife，这是我们使用的另一个注释库。

-keepattributes *Annotation*
-dontwarn butterknife.internal.**
-keep class **$$ViewInjector { *; }
-keepnames class * { @butterknife.InjectView *;}

有谁知道添加的标志来使 Lombok 开心。

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.**

最佳答案

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，您可以将jar分解为包含在您的库中的lombok-api.jar。我尝试查找说明，但找不到解释该操作方法的页面(这是一年多以前的，因此可能已更改)。

感谢Roel(如下)，这是要使用的命令行:java -jar lombok.jar publicApi
