-= Vert.x Gradle Starter
+# SmartOS exporter
 
-This project is a template to start your own Vert.x project using Gradle.

-== Prerequisites
-
-* JDK 8+
-
-== Getting started
-
-Create your project with:
-
-[source]
-----
-git clone https://github.com/vert-x3/vertx-gradle-starter.git PROJECT_NAME
-----
-
-Replace `PROJECT_NAME` with the name of your project.
-
-On Linux and MacOSx (or Windows with `bash`), if you want to go faster and generate an already configured project run:
-
-[source]
-----
-curl http://vertx.io/assets/starter-scripts/create-vertx-project-gradle.sh -o vertx-create-gradle-project.sh; bash vertx-create-gradle-project.sh
-----
-
-== Running the project
-
-Once you have retrieved the project, you can check that everything works with:
-
-[source]
-----
-./gradlew test run
-----
-
-The command compiles the project and runs the tests, then  it launches the application, so you can check by yourself. Open your browser to http://localhost:8080. You should see a _Hello World_ message.
-
-== Anatomy of the project
-
-The project contains:
-
-* the Gradle project and its configuration (`build.gradle`)
-* a _main_ verticle file (src/main/java/io/vertx/starter/MainVerticle.java)
-* a unit test (src/main/test/io/vertx/starter/MainVerticleTest.java)
-
-== Start to hack
-
-1. Delete the `.git` directory
-2. Open the `build.gradle` file and customize the `version`. You can also change the `mainVerticleName` variable to use your own package name and verticle class.
-3. Run `./gradlew run`.
-
-This last command relaunches Gradle and the application as soon as you change something in `src/main`.
-
-== Building the project
-
-To build the project, just use:
-
-----
-./gradlew shadowJar
-----
-
-It generates a _fat-jar_ in the `build/libs` directory.
-
-
-
-
------------
-This project shows how to use the Vert.x 3.2 redeploy feature. Vert.x watches for file changes and will then compile these changes. The hello world verticle will be redeployed automatically.
-Simply start the application with:
-
-    ./gradlew run
-
-Now point your browser at http://localhost:8080. Then you can make changes to the hello world verticle and reload the browser.
-
-The whole configuration for this is rather simple:
-
-    mainClassName = 'io.vertx.core.Launcher'
-    def mainVerticleName = 'io.vertx.example.HelloWorldVerticle'
-
-    // Vert.x watches for file changes in all subdirectories
-    // of src/ but only for files with .java extension
-    def watchForChange = 'src/**/*.java'
-
-    // Vert.x will call this task on changes
-    def doOnChange = './gradlew classes'
-
-    run {
-        args = ['run', mainVerticleName, "--redeploy=$watchForChange", "--launcher-class=$mainClassName", "--on-redeploy=$doOnChange"]
-    }
