一、问题描述

刚把app项目的compileSdkVer 改为 28，buildToolsVer改为"28.0.3"之后，编译失败了，失败错误如下所示：

好吧，提示我proguard-third-party.pro 文件中 51行，关于jackson的混淆出问题了。

Caused by: java.io.IOException: proguard.ParseException: Use of generics not 
allowed for java type at 
'com.fasterxml.jackson.databind.introspect.VisibilityChecker$Std.<clinit>' in line 
51 of file '/data/jenkins/workspace/AP_DevelopGlobal/watch/proguard-third-party.pro'

关于proguard-third-party.pro 文件在

一文中已经有介绍，这个proguard-third-party.pro 文件是通用的第三方AAR库的混淆配置

之前的配置是
在这里插入图片描述

# >>>>>>>>>>>>>>>>>>>>>>>>  Jackson  Start >>>>>>>>>>>>>>>>>>>>>>>>
-dontwarn com.fasterxml.jackson.databind.**
-keep class com.fasterxml.jackson.core.** {*;}
-keep interface com.fasterxml.jackson.core { *; }
-keep public class * extends com.fasterxml.jackson.core.**
-keep class com.fasterxml.jackson.databind.introspect.VisibilityChecker$Std.<clinit>
-keep class com.fasterxml.jackson.databind.ObjectMapper.<clinit>
-keep class com.fasterxml.jackson.databind.** {*;}
-keep class com.fasterxml.jackson.databind.introspect.VisibilityChecker$*{*;}
-keep interface com.fasterxml.jackson.databind { *; }
-keep public class * extends com.fasterxml.jackson.databind.**
# >>>>>>>>>>>>>>>>>>>>>>>>  Jackson  End >>>>>>>>>>>>>>>>>>>>>>>>

好吧，找到了地方，现在怀疑是不是 混淆配置需要升级了？

二、解决问题

2.1 找到jackson的官网关于混淆的说明

先找到jackson的官网，关于jackson的混淆配置的说明

在这里插入图片描述

好吧，看起来这些配置和我的混淆配置有点不一样。我们试着更新一下混淆配置。

2.2 更新jackson的混淆配置

将官网上的混淆配置都更新下来，注释掉之前的混淆配置，如下所示：
在这里插入图片描述


# >>>>>>>>>>>>>>>>>>>>>>>>  Jackson  Start >>>>>>>>>>>>>>>>>>>>>>>>
#-dontwarn com.fasterxml.jackson.databind.**
#-keep class com.fasterxml.jackson.core.** {*;}
#-keep interface com.fasterxml.jackson.core { *; }
#-keep public class * extends com.fasterxml.jackson.core.**
#-keep class com.fasterxml.jackson.databind.introspect.VisibilityChecker$Std.<clinit>
#-keep class com.fasterxml.jackson.databind.ObjectMapper.<clinit>
#-keep class com.fasterxml.jackson.databind.** {*;}
#-keep class com.fasterxml.jackson.databind.introspect.VisibilityChecker$*{*;}
#-keep interface com.fasterxml.jackson.databind { *; }
#-keep public class * extends com.fasterxml.jackson.databind.**

# https://github.com/FasterXML/jackson-docs/wiki/JacksonOnAndroid
# Jackson
-keep @com.fasterxml.jackson.annotation.JsonIgnoreProperties class * { *; }
-keep @com.fasterxml.jackson.annotation.JsonCreator class * { *; }
-keep @com.fasterxml.jackson.annotation.JsonValue class * { *; }
-keep class com.fasterxml.** { *; }
-keep class org.codehaus.** { *; }
-keepnames class com.fasterxml.jackson.** { *; }
-keepclassmembers public final enum com.fasterxml.jackson.annotation.JsonAutoDetect$Visibility {
    public static final com.fasterxml.jackson.annotation.JsonAutoDetect$Visibility *;
}

# General
-keepattributes SourceFile,LineNumberTable,*Annotation*,EnclosingMethod,Signature,Exceptions,InnerClasses

# Proguard configuration for Jackson 2.x
-keep class com.fasterxml.jackson.databind.ObjectMapper {
    public <methods>;
    protected <methods>;
}
-keep class com.fasterxml.jackson.databind.ObjectWriter {
    public ** writeValueAsString(**);
}
-keepnames class com.fasterxml.jackson.** { *; }
-dontwarn com.fasterxml.jackson.databind.**
# Proguard configuration for Jackson 2.x
-dontwarn com.fasterxml.jackson.databind.**
-keepclassmembers class * {
    @com.fasterxml.jackson.annotation.* *;
 }

# Proguard configuration for Jackson 2.x
-dontwarn com.fasterxml.jackson.databind.**
-keepclassmembers class * {
     @com.fasterxml.jackson.annotation.* *;
}

# >>>>>>>>>>>>>>>>>>>>>>>>  Jackson  End >>>>>>>>>>>>>>>>>>>>>>>>

2.3 更新完后，提交代码，重新编译。

更新完混淆配置之后，重新编译不再报这个错误，编译成功了！。
