使用gradle从单个源代码构建多个jar

Question

我正在使用gradle构建项目的Java应用程序。 gradle构建会创建一个模糊的可执行jar。

我在项目中使用过log4j库，我想使用gradle创建两个带有调试日志的jar，一个没有调试日志的jar。

build.gradle

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath "net.sf.proguard:proguard-gradle:6.1.1"
    }
}
plugins {
    id 'java'
    id 'maven-publish'
}

repositories {
    maven {
        url = 'http://repo.maven.apache.org/maven2'
    }
}

dependencies {
    compile 'org.testng:testng:6.14.3'
    compile 'io.appium:java-client:7.0.0'
    compile 'org.apache.poi:poi:3.16'
    compile 'net.sourceforge.tess4j:tess4j:4.3.0'
    compile 'log4j:log4j:1.2.17'
    testCompile 'junit:junit:4.11'
}

group = 'com.mobile'
version = '0.1'
description = 'AppiumTest'
sourceCompatibility = '1.8'

publishing {
    publications {
        maven(MavenPublication) {
            from(components.java)
        }
    }
}

jar{
    duplicatesStrategy = 'exclude'
    from { configurations.compile.collect { zipTree(it) } }
    manifest {
        attributes 'Implementation-Title': 'Jar File with dependencies',  
            'Implementation-Version': version,
            'Main-Class': 'com.mobile.MobileTest.App'
    }
}

task proguardTask(type: proguard.gradle.ProGuardTask,dependsOn: jar) {
    configuration file('proguard.pro')
    injars 'build/libs/MobileTest-0.1.jar'
    outjars 'build/libs/MobileTest-0.1-obfus.jar'
    libraryjars "${System.getProperty('java.home')}/lib/rt.jar" 
}

tasks.withType(JavaCompile) {
    options.encoding = 'UTF-8'
}

test {
    useTestNG()
}

任何帮助将不胜感激。
