Spring boot where is my jar file

Spring boot makes it really easy to setup a simple app. But it takes me longer to actually get a jar file which I can upload to a remote server. I am using IntelliJ, no command line, and I use gradle. The application is running somehow out of Intellij. But where are the created files? Where is my jar from Bootjar?

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:2.0.0.RELEASE")
    }
}

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

bootJar {
    baseName = 'gs-spring-boot'
    version =  '0.1.0'
}

repositories {
    mavenCentral()
}

sourceCompatibility = 1.8
targetCompatibility = 1.8

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

    compile("org.springframework.boot:spring-boot-starter-actuator")

    testCompile("org.springframework.boot:spring-boot-starter-test")

    // add spring data repos
    compile("org.springframework.boot:spring-boot-starter-data-jpa")

    compile("org.postgresql:postgresql:42.2.4")

    // REST interface
    compile("org.springframework.boot:spring-boot-starter-data-rest")

    // Security
    compile("org.springframework.boot:spring-boot-starter-security")
}
