spring-boot - 如何使用spring-boot gradle插件进行维护

Question

如何使用Spring Boot 2和Gradle构建来设置Proguard模糊处理？

你好。尝试使用其gradle插件和Proguard gradle插件设置Spring Boot应用程序的代码混淆。 Google大多提供了一些针对较早的spring-boot-gradle-plugin版本(即使用不存在的bootRepackage任务的this closest one)或使用maven插件(具有重新打包目标)的方法。

据我了解，我的想法是在jar打包之前混淆类，但是在当前gradle插件版本中看不到任何入口点，并且希望避免手动提取和回退。

有人在使用那个组合吗？ Spring Boot版本> = 2.0.3。

Answer 1

我认为今天是不可能的，您必须手动提取并压缩回去。

手动提取和压缩后的示例可能会有所帮助:

build.gradle

version = '0.1.0'

buildscript {
    dependencies {
        classpath 'net.sf.proguard:proguard-gradle:6.0.3'
        classpath 'net.sf.proguard:proguard-base:6.0.3'
    }
}

apply plugin: 'java'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'

task extractJar(type: Copy) {
    def zipFile = file("${buildDir}/libs/your_project_name-${version}.jar")
    def outputDir = file("${buildDir}/unpacked/")

    from zipTree(zipFile)
    into outputDir
}

task proguard(type: proguard.gradle.ProGuardTask) {
    doFirst {
        tasks.extractJar.execute();
    }
    configuration 'proguard.conf'
    injars  "${buildDir}/unpacked/BOOT-INF/classes"
    outjars "${buildDir}/obfClasses"

    libraryjars "${System.getProperty('java.home')}/lib/rt.jar"
    libraryjars "${buildDir}/unpacked/BOOT-INF/lib"

    doLast {
        tasks.deleteClasses.execute();
    }
}

task deleteClasses(type: Delete) {
    delete "${buildDir}/unpacked/BOOT-INF/classes/"

    doLast {
        tasks.copyObfuscatedClasses.execute()
    }
}

task copyObfuscatedClasses(type: Copy) {
    from "${buildDir}/obfClasses"
    into "${buildDir}/unpacked/BOOT-INF/classes/"
    include 'com/**'
    include '*.properties'

    doLast {
        tasks.copyObfuscatedJars.execute()
    }
}

task copyObfuscatedJars(type: Copy) {
    from "${buildDir}/obfClasses"
    into "${buildDir}/unpacked/BOOT-INF/lib/"
    include '*.jar'

    doLast {
        tasks.deleteObfuscated.execute()
    }
}

task deleteObfuscated(type: Delete) {
    delete 'build/obfClasses'

    doLast {
        tasks.repackage.execute()
    }
}

task repackage(type: Zip) {
    from  "${buildDir}/unpacked"
    entryCompression ZipEntryCompression.STORED
    archiveName "your_project_name-${version}-obf.jar"
    destinationDir(file("${buildDir}/libs"))
}
