# Getting started

version 2.3.7

## 1. Download

In this download area, you will be able to download the distribution (binary and source), the Windows installer and the documentation for Groovy.

For a quick and effortless start on Mac OSX, Linux or Cygwin, you can use GVM (the Groovy enVironment Manager) to download and configure any Groovy version of your choice. Basic instructions can be found below.

### 1.1. Stable

- Download zip: Binary Release | Source Release

- Download documentation: JavaDoc and zipped online documentation

- Combined binary / source / documentation bundle: Distribution bundle

You can learn more about this version in the release notes or in the JIRA release notes.

If you plan on using invokedynamic support, read those notes.

### 1.2. Snapshots

For those who want to test the very latest versions of Groovy and live on the bleeding edge, you can use our snapshot builds. As soon as a build succeeds on our continuous integration server a snapshot is deployed to Codehaus’ snapshot repository.

## 2. Maven Repository

If you wish to embed Groovy in your application, you may just prefer to point to your favourite maven repositories or the codehaus maven repository.

### 2.1. Stable Release

Gradle | Maven | Explanation
--- | --- | ---
'org.codehaus.groovy:groovy:2.3.7' | <groupId>org.codehaus.groovy</groupId> <artifactId>groovy</artifactId> <version>2.3.7</version> | Just the core of groovy without the modules (see below). Treats Antlr, ASM, etc. as standard dependencies. Only useful if you happen to also use the same versions of these jars yourself as it will save you having two copies of these jars.
'org.codehaus.groovy:groovy-$module:2.3.7' | <groupId>org.codehaus.groovy</groupId> <artifactId>groovy-$module</artifactId> <version>2.3.7</version> | "$module" stands for the different optional groovy modules "ant", "bsf", "console", "docgenerator", "groovydoc", "groovysh", "jmx", "json", "jsr223", "servlet", "sql", "swing", "test", "testng" and "xml". Example: <artifactId>groovy-sql</artifactId>
'org.codehaus.groovy:groovy-all:2.3.7' | <groupId>org.codehaus.groovy</groupId> <artifactId>groovy-all</artifactId> <version>2.3.7</version> | The core plus all the modules. Also includes jar versions of Antlr, ASM, Commons-CLI and Retrotranslator runtime. Allows you or your other dependencies (e.g. Hibernate) to use other versions of these jars. Optional dependencies are marked as optional. You may need to include some of the optional dependencies to use some features of Groovy, e.g. AntBuilder, GroovyMBeans, etc.

To use the InvokeDynamic version of the jars just append ':indy’ for Gradle or <classifier>indy</classifier> for Maven.

### 2.2. Snapshot Releases

In addition to the stable and milestone releases you can find intermediate SNAPSHOT releases at the codehaus snapshot maven repository.

## 3. GVM (the Groovy enVironment Manager)

This tool makes installing Groovy on any Bash platform (Mac OSX, Linux, Cygwin, Solaris or FreeBSD) very easy.

Simply open a new terminal and enter:

    $ curl -s get.gvmtool.net | bash

Follow the instructions on-screen to complete installation.

Open a new terminal or type the command:

    $ source "$HOME/.gvm/bin/gvm-init.sh"

Then install the latest stable Groovy:

    $ gvm install groovy

After installation is complete and you’ve made it your default version, test it with:

    $ groovy -version

That’s all there is to it!

## 4. Other ways to get Groovy

### 4.1. Installation on Mac OS X

#### 4.1.1. MacPorts

If you’re on MacOS and have MacPorts installed, you can run:

    sudo port install groovy

#### 4.1.2. Homebrew

If you’re on MacOS and have Homebrew installed, you can run:

    brew install groovy

### 4.2. Installation on Windows

If you’re on Windows, you can also use the NSIS Windows installer.

### 4.3. Other Distributions

You may download other distributions of Groovy from this site.

### 4.4. Source Code

If you prefer to live on the bleeding edge, you can also grab the source code from GitHub.

### 4.5. IDE plugin

If you are an IDE user, you can just grab the latest IDE plugin and follow the plugin installation instructions.

## 5. Install Binary

These instructions describe how to install a binary distribution of Groovy.

- First, Download a binary distribution of Groovy and unpack it into some file on your local file system.

- Set your `GROOVY_HOME` environment variable to the directory you unpacked the distribution.

- Add `GROOVY_HOME/bin` to your `PATH` environment variable.

- Set your `JAVA_HOME` environment variable to point to your JDK. On OS X this is `/Library/Java/Home`, on other unixes its often `/usr/java` etc. If you’ve already installed tools like Ant or Maven you’ve probably already done this step.

You should now have Groovy installed properly. You can test this by typing the following in a command shell:

    groovysh

Which should create an interactive groovy shell where you can type Groovy statements. Or to run the Swing interactive console type:

    groovyConsole

To run a specific Groovy script type:

    groovy SomeScript
