[swagger-codegen-3.0.0-rc0] Inflector missing gradle support

Description

java -jar swagger-codegen-cli.jar generate \
  -i testing_openapi_3.json \
  -l inflector -o server/

Inflector on the 3.0.0 branch lacks gradle support. A pom.xml file is generated, however there's nobuild.gradle

Swagger-codegen version

3.0.0

Suggest a fix/enhancement

Here's my gradle script.

plugins {
    id 'org.akhikhl.gretty' version '2.0.0'
}

apply plugin: 'java'
apply plugin: 'maven'

group = 'io.swagger'
version = '1.0.0'

description = """swagger-inflector-server"""

sourceCompatibility = 1.8
targetCompatibility = 1.8
tasks.withType(JavaCompile) {
	options.encoding = 'UTF-8'
}

// http://akhikhl.github.io/gretty-doc/Gretty-configuration.html
gretty {
    httpPort = 8080
    contextPath = '/'
    httpIdleTimeout = 60000
    scanInterval = 1
    scanDir 'inflector.yaml'
    scanDir 'src/main/swagger/swagger.yaml'
}

sourceSets {
    main {
        java {
            srcDirs 'src/gen/java'
        }
    }
}

repositories {
    jcenter()
}

dependencies {
    compile 'io.swagger:swagger-inflector:2.0.0-rc1'
}

Why is maven supported? It seems like it'd be less work to standardize on Gradle.
