I'm trying to build a Gradle file and getting the error `Build file '.../build.gradle' is not part of the build defined by settings file '.../settings.gradle'. If this is an unrelated build, it must have it's own settings file.`

Here is my build.gradle:

```
buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:2.1.4.RELEASE")
    }
}

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

bootJar {
    baseName = 'gs-securing-web'
    version =  '0.1.0'
}

repositories {
    mavenCentral()
}

sourceCompatibility = 1.8
targetCompatibility = 1.8

dependencies {
    compile("org.springframework.boot:spring-boot-starter-thymeleaf")
    compile("org.springframework.boot:spring-boot-starter-web")
    // tag::security[]
    compile("org.springframework.boot:spring-boot-starter-security")
    // end::security[]
    testCompile("junit:junit")
    testCompile("org.springframework.boot:spring-boot-starter-test")
    testCompile("org.springframework.security:spring-security-test")
}

```

Here is my settings.gradle:

```
/*
 * This settings file was generated by the Gradle 'init' task.
 *
 * The settings file is used to specify which projects to include in your build.
 * In a single project build this file can be empty or even removed.
 *
 * Detailed information about configuring a multi-project build in Gradle can be found
 * in the user guide at https://docs.gradle.org/4.0/userguide/multi_project_builds.html
 */

/*
// To declare projects as part of a multi-project build use the 'include' method
include 'shared'
include 'api'
include 'services:webservice'
*/

rootProject.name = 'gs-securing-web'

```

How do I get this to build?
