Java 如何混淆一个胖子和克拉斯马斯特

我有一个胖罐子，它是使用gradle脚本生成的。运行以下命令时发布gradle脚本：-

java-jarfilename.jar

它正在运行主方法，一切正常。然而，当我试图混淆这个jar时，结果jar会抱怨：-

错误：无效或损坏的jarfile ObfusactedTest.jar

我的代码如下：-

build.gradle：-

    buildscript {
    repositories {
        mavenLocal()
        mavenCentral()
    }

    dependencies {
        classpath files("E:\\softs\\ZKM\\ZKMEval\\ZKM.jar") //ZKM_JAR_PATH must be set to point to your ZKM.jar
        classpath 'com.zelix.gradle:plugin:1.0.0'
    }
}

apply plugin: 'java'
apply plugin: 'maven'
apply plugin: 'com.zelix.gradle.plugin'

group = 'com.github.jitpack'

sourceCompatibility = 1.8 // java 8
targetCompatibility = 1.8

repositories {
    mavenLocal()
    mavenCentral()
}

dependencies {
    compile group: 'org.apache.commons', name: 'commons-lang3', version: '3.11'
    compile group: 'org.apache.commons', name: 'commons-collections4', version: '4.4'
}

jar {
    manifest {
        attributes "Main-Class": "com.github.jitpack.Hello"
    }
    zip64 = true
    from {
        configurations.compile.collect { it.isDirectory() ? it : zipTree(it) }
    }
}


zkmSetting {
    scriptName = "Obfuscate.txt" //Must be set to point to the ZKM Script to execute.
}

Obfuscate.txt：-

print "Obfuscating fatJar.....";

classpath
          "C:\Program Files\Java\jdk-10.0.2\lib\jrt-fs.jar"
          ".\obfuscateFatJar.jar";

open ".\obfuscateFatJar.jar" {"*.class"};

exclude org.apache.commons.*.*;
exclude com.github.jitpack.Hello.*;

obfuscate keepInnerClassInfo=false
           keepGenericsInfo=true
           exceptionObfuscation=heavy
           encryptStringLiterals=flowObfuscate;

saveAll archiveCompression=asIs
        deleteEmptyDirectories=true
        deleteXMLComments=false
        "ObfusactedTest.jar";

顺便说一下，Hello.java已经获得了main方法。

您的ZKM脚本“open”语句指定了{“*.class”}文件过滤器。因此，您要过滤掉所有非类文件，包括MANIFEST.MF。看

缺少MANIFEST.MF将导致“无效或损坏的jarfile”错误。请注意，Zelix KlassMaster日志文件将包含如下消息

消息：过滤掉路径'obfuscateFatJar.jar！META-INF/MANIFEST.MF'，因为它与指定的筛选器“{.class”}>”（D）不匹配*

---

您可以通过不使用文件筛选器（本例中最安全的选项）或扩展文件筛选器以包括其他文件类型来解决此问题。例如，{.class“| |“.MF”}

更新类路径中的过滤器。代码现在看起来像这样。工作起来很有魅力

execute "del ObfusactedTest.jar";

classpath
          "C:\Program Files\Java\jdk-10.0.2\lib\jrt-fs.jar"
          ".\obfuscateFatJar.jar";

open ".\obfuscateFatJar.jar" {"*.class" || "*.MF"};

exclude org.apache.commons.*.*;

obfuscate keepInnerClassInfo=false
           keepGenericsInfo=true
           exceptionObfuscation=heavy
           encryptStringLiterals=flowObfuscate;

saveAll archiveCompression=asIs
        deleteEmptyDirectories=true
        deleteXMLComments=false
        "ObfusactedTest.jar";
