我如何利用gradle application 插件从gradle执行胖JAR：

thufir@doge:~/NetBeansProjects/selenium$ 
thufir@doge:~/NetBeansProjects/selenium$ gradle clean fatJar;java -jar build/libs/selenium-all.jar

的build.gradle：

plugins {
    id 'com.gradle.build-scan' version '1.8' 
    id 'java'
    id 'application'
}

mainClassName = 'net.bounceme.dur.web.selenium.Main'

buildScan {
    licenseAgreementUrl = 'https://gradle.com/terms-of-service'
    licenseAgree = 'yes'
}

repositories {
    jcenter()
}

jar {
    manifest {
        attributes 'Main-Class': 'net.bounceme.dur.web.selenium.Main'
        attributes 'Class-path': 'selenium-java-3.4.0.jar'
    }
}

task fatJar(type: Jar) {
    baseName = project.name + '-all'
    from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } }
    with jar
    manifest {
        attributes 'Implementation-Title': 'Gradle Quickstart', 'Implementation-Version': '3.4.0'
        attributes 'Main-Class': 'net.bounceme.dur.web.selenium.Main'
    }
}

dependencies {
     compile group: 'org.seleniumhq.selenium', name: 'selenium-java', version: '3.4.0'
     compile group: 'org.seleniumhq.selenium', name: 'selenium-server', version: '3.4.0'

    compile group: 'org.seleniumhq.selenium', name: 'selenium-firefox-driver', version: '3.4.0'
    compile group: 'org.seleniumhq.selenium', name: 'selenium-chrome-driver', version: '3.4.0'
    compile group: 'org.seleniumhq.selenium', name: 'selenium-ie-driver', version: '3.4.0'
    compile group: 'org.seleniumhq.selenium', name: 'selenium-safari-driver', version: '3.4.0'
    compile group: 'org.seleniumhq.selenium', name: 'selenium-edge-driver', version: '3.4.0'

}

条件是我希望胖JAR实际构建并希望自己执行 actual JAR文件 . 在从CLI运行fatJAR的context中 .

    你需要的是添加一个 JavaExec 类型的任务，它将配置类路径以包含使用 fatJar 和主类集构建的jar . 这是我准备的 build.gradle ，它显示了它应该是什么样子：

    plugins {
    id 'java'
}

repositories {
    jcenter()
    mavenCentral()
}

task fatJar(type: Jar) {
    baseName = project.name + '-all'
    from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } }
    with jar
    manifest {
        attributes 'Main-Class': 'org.Lol'
    }
}

dependencies {
    compile 'com.google.guava:guava:22.0'
}

task runFatJar(type: JavaExec) {
    dependsOn fatJar
    classpath = fatJar.outputs.files
    main = 'org.Lol'
}

    和here你可以找到可运行的演示 .
