I have created a sample application in Spring Boot and it is running properly in IDE. I want to package it as a fat JAR and run it through command prompt. How do I do it? I am running it using java -jar JarName.jar. This is my build script:

buildscript {
    ext {
        springBootVersion = '1.1.9.RELEASE'
    }
    repositories {
        mavenCentral()
        jcenter()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
        classpath 'eu.appsatori:gradle-fatjar-plugin:0.3'
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'spring-boot' 
apply plugin: 'eu.appsatori.fatjar'

jar {
    baseName = 'demo'
    version = '0.0.1-SNAPSHOT'
}


fatJar{
    manifest {
     attributes 'Implementation-Title': 'Gradle Jar File Example',
    //      'Implementation-Version': version,
        'Main-Class': 'PachName.Application'
     }

}

sourceCompatibility = 1.7
targetCompatibility = 1.7

repositories {
    mavenCentral()
}


dependencies {
    compile("org.springframework.boot:spring-boot-starter-web")
    testCompile("org.springframework.boot:spring-boot-starter-test")
}

eclipse {
    classpath {
         containers.remove('org.eclipse.jdt.launching.JRE_CONTAINER')
         containers 'org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.7'
    }
}

fatJarPrepareFiles {
    include 'application.properties'

  }

task wrapper(type: Wrapper) {
    gradleVersion = '1.12'
}
