使用proguard混淆java9代码-码匠的流水账君须怜我
序
本文主要研究一下如何使用proguard混淆java9代码maven
<plugin> <groupId>com.github.wvengen</groupId> <artifactId>proguard-maven-plugin</artifactId> <executions> <execution><phase>package</phase><goals><goal>proguard</goal></goals> </execution> </executions> <configuration> <proguardVersion>6.0.1</proguardVersion> <injar>${project.build.finalName}.jar</injar> <outjar>${project.build.finalName}.jar</outjar> <inFilter>!META-INF/maven/**,!module-info.class</inFilter> <obfuscate>true</obfuscate> <proguardInclude>${project.basedir}/proguard.cfg</proguardInclude> <libs><lib>${java.home}/jmods/java.base.jmod(迸溅的拼音 !**.jar;勇者传说ol !module-info.class)</lib> </libs> </configuration> <dependencies> <dependency><groupId>net.sf.proguard</groupId><artifactId>proguard-base</artifactId><version>6.0.1</version><scope>runtime</scope> </dependency> </dependencies></plugin>
这里使用6.0.1版本的proguard-baseproguard.cfg
-target 9-dontshrink-dontoptimize-useuniqueclassmembernames-adaptclassstrings-dontusemixedcaseclassnames-keepattributes Exceptions,InnerClasses王严化 ,Signature仁德王后 ,Deprecated,SourceFile邪恶内涵漫画 ,LineNumberTable全民绯闻 ,*Annotation*,EnclosingMethod-keepclasseswithmembers public class * { public static void main(java.lang.String[]);}
这里target要指定为9版本问题duplicate class definitions
[proguard] Warning: class [META-INF/versions/9/org/apache/logging/log4j/util/ProcessIdUtil.class] unexpectedly contains class [org.apache.logging.log4j.util.ProcessIdUtil] [proguard] Reading library jar [/Users/demo/.m2/repository/org/apache/logging/log4j/log4j-to-slf4j/2.10.0/log4j-to-slf4j-2.10.0.jar] [proguard] Reading library jar [/Users/demo/.m2/repository/org/apache/logging/log4j/log4j-api/2.10.0/log4j-api-2.10.0.jar] [proguard] Note: duplicate definition of library class [org.apache.logging.log4j.util.ProcessIdUtil] [proguard] Note: duplicate definition of library class [org.apache.logging.log4j.util.StackLocator] [proguard] Reading library jar [/Users/demo/.m2/repository/org/slf4j/jul-to-slf4j/1.7.25/jul-to-slf4j-1.7.25.jar] [proguard] Reading library jar [/Users/demo/.m2/repository/javax/annotation/javax.annotation-api/1.3.2/javax.annotation-api-1.3.2.jar] [proguard] Warning: class [META-INF/versions/9/org/apache/logging/log4j/util/StackLocator.class] unexpectedly contains class [org.apache.logging.log4j.util.StackLocator][proguard] Note: there were 2 duplicate class definitions. [proguard] (http://proguard.sourceforge.net/manual/troubleshooting.html#duplicateclass) [proguard] Warning: there were 2 classes in incorrectly named files. [proguard] You should make sure all file names correspond to their class names. [proguard] The directory hierarchies must correspond to the package hierarchies. [proguard] (http://proguard.sourceforge.net/manual/troubleshooting.html#unexpectedclass) [proguard] If you don't mind the mentioned classes not being written out消灾寺 , [proguard] you could try your luck using the '-ignorewarnings' option. [proguard] Error: Please correct the above warnings first.
如果没有使用到log4j的话，可以在progurard.cfg文件中配置dontwarn忽略can’t find referenced class
[proguard] Warning: cn.example.Demo: can't find referenced class java.io.ByteArrayOutputStream [proguard] Warning: there were 858 unresolved references to classes or interfaces. [proguard] You may need to add missing library jars or update their versions. [proguard] If your code works fine without the missing classes慕璎珞 , you can suppress [proguard] the warnings with '-dontwarn' options. [proguard] (http://proguard.sourceforge.net/manual/troubleshooting.html#unresolvedclass) [proguard] Warning: there were 1 unresolved references to library class members. [proguard] You probably need to update the library versions. [proguard] (http://proguard.sourceforge.net/manual/troubleshooting.html#unresolvedlibraryclassmember) [proguard] Error: Please correct the above warnings first.
这种多半是没有配置好libraryjars的问题，比如这里就是没有配置java.base.jmod的问题官仙笔趣阁 。如果还依赖有其他jmod，可以根据具体日志修改配置酒井朝香 。塔琳托娅Can’t read java.base.jmod
[proguard] Reading library directory [/Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Home/jmods/java.base.jmod(!**.jar;丹尼爱特 !module-info.class)] [proguard] Error: Can't read [/Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Home/jmods/java.base.jmod(!**.jar;!module-info.class)] (No such file or directory: /Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Home/jmods/java.base.jmod(杨佳音 !**.jar;!module-info.class))
这个是在maven的pom文件配置lib引起的
<libs><lib>${java.home}/jmods/java.base.jmod(!**.jar;!module-info.class)</lib> </libs>
可能是该plugin的问题小背篓铃声 ，将其配置移到proguard.cfg就可以
-libraryjars <java.home>/jmods/java.base.jmod(放狠爱 !.jar;!module-info.class)小结
这里的例子仅仅还是jdk是模块化的，但是工程代码还没有模块化。等所有依赖都魔域帝国 模块化了暖床侍妾，可以重新试验一下。doc

Note: duplicate definition of program/library class
